Placental Repository to Improve Infant Lung Outcomes in Preeclampsia 

The BMC PRIME study is a longitudinal prospective study evaluating placental secreted proteins from preeclamptic pregnancies.  Preeclampsia is a hypertensive disorder of pregnancy that is strongly associated with neonatal lung and gut disorders for premature infants.  Through the PRIME study, Dr. Taglauer will seek to identify unique signaling proteins from preeclamptic placentas that are connected with pathways of lung and gut developmental injury. The PRIME study will also be creating a highly valuable biorepository of preeclamptic placental samples that will be available for collaborative studies. 

Dr. Elizabeth Taglauer  is a neonatologist and placental biologist who has developed a unique niche as a physician-scientist to explore how the intrauterine environment can be optimized to improve neonatal outcomes. In her faculty research at Boston Medical Center, Dr. Taglauer is applying her placental expertise to examine how perinatal exposures impact neonatal outcomes.  The main focus of her work is on the antenatal determinants of neonatal lung and gut disease, seeking to understand how human placental dysregulation impacts fetal lung and gut development.  Dr. Taglauer’s research incorporates human placental components with translational human developmental model systems with a long-term goal of optimizing infant development and health outcomes.

Validity, Acceptability, and Utility of Electronic Health Record Household Linking

Although there is common consensus that clinicians and the health system need to focus on providing care for households, there are few tools that facilitate this process, particularly in the electronic health record. Recently, research methods have been developed to link household members together in the electronic health record. These tools afford a promising opportunity to better direct care towards families as a whole, and to study the effects of family-level care. However the validity, effectiveness, and acceptability of these tools haven’t been well-studied, leaving a major gap in our ability to translate these research tools into clinical care. In this project, we plan to evaluate how effective household linkage tools are by interviewing patients about their household membership, and cross-referencing their descriptions of household composition with household membership gathered through electronic health record linking. We will focus on a key disease that clusters within families, but for which there are few family-level care options: latent tuberculosis infection. We will also interview patients and clinicians about the acceptability of existing and anticipated household linking tools to better understand how these tools could be used, and to anticipate potential challenges to implementing them. The steps we’re taking in this project provide necessary groundwork for translating a promising research tool—electronic health record household linking—to the clinic and the bedside.

A soft-foldable Robotic Eetractor with Integrated Pressure Sensing to Reduce Tissue Trauma in Neurosurgery and Skull Base Surgery

Brain retraction systems are frequently required to achieve surgical exposure of deep-seated brain lesions. Retraction, however, can cause localized stress areas and is associated with complications that include brain edema, vascular compromise causing ischemia, and direct damage to the surrounding cortex.

This pilot project will focus on the design, development, and evaluation of a novel soft robotic neurosurgical retractor to tackle current clinical barriers in neurological surgery and skull base surgery. The proposed system is designed to facilitate neurosurgery by creating a minimally invasive surgical workspace in the brain (through expansion and unfolding of pneumatically driven origami-inspired soft robotic actuators) and monitor robot/tissue interaction (via soft capacitive pressure sensors).

This soft robot provides the capability to tune the amount of tissue retraction via actively expanding and contracting its structure by controlling its internal actuation state, and continuously monitor its interaction with the surrounding environment (i.e., brain tissue) while informing the surgeon. The purpose of this device is to address critical unmet needs within the world of brain tumor surgery, such as increasing safety and the depth of access in deep-seated tumor brain locations, improving navigability within the brain, and enabling surgeon awareness during the procedure.

A soft Robotic Catheter for Percutaneous Management of Non-compressible Torso Hemorrhage

In the US, injury accounts for over 150,000 deaths and over 3 million injuries per year. Hemorrhage, secondary to traumatic injury, is the leading cause of death of Americans from one to 46 years of age. Noncompressible torso hemorrhage is a leading cause of mortality in patients with trauma.

Resuscitative endovascular balloon occlusion of the aorta (REBOA) is a minimally invasive intervention for temporary control of non-compressible torso hemorrhage originating below the diaphragm to stabilize the patient until they are brought to a hospital for treatment. While it may be lifesaving, the aortic occlusion, can cause severe long term consequences for patients. This project focuses on developing a novel device to enable controllable occlusion of the aorta to allow stabilization of the hemorrhage without completely cutting off blood flow to the lower extremities. The device will be designed to provide a safer alternative to current devices for management of non-compressible hemorrhage. The device will be designed to be easy to use by enabling automation of the hemorrhage control process via robotic technologies.

Developing a Family-Based Program to Enhance Autonomy in Adults with Down Syndrome

Down syndrome is the most common chromosomal cause of intellectual disability. Longevity in Down syndrome has increased significantly over the past 30 years, largely due to better care of congenital heart conditions. Most research on Down syndrome in adulthood has focused on the genetic effects of trisomy 21, co-occurring medical conditions, and more recently on pharmacological treatments. The current project focuses on improving daily quality of life of adults with Down syndrome. We will use a community-engaged qualitative approach to develop an online family-based program to promote autonomy in adults with Down syndrome. Building on prior work by our multidisciplinary research team, we will develop Project REACH (Ready to Enhance Autonomy in the Community and Home) – a community-based short-term program, delivered via telehealth, individualized for each family, and focused on skill-building. Through qualitative interviews with adults with Down syndrome, family members, and service providers, we will develop and finalize the content and delivery approach for Project REACH. Specifically, the objectives of this research are to: (1) develop Project REACH for adults with Down syndrome and their family members, (2) inform future implementation of Project REACH by identifying possible barriers, facilitators, scale-up potential, and sustainability in a real-world setting (a local service agency), and (3) prepare a Project REACH program manual and materials to support a subsequent grant application for a clinical trial.

Radiation Therapy Resistance Promoted by LSD1 in Oral Cancer

Radiation therapy resistance promoted by LSD1 in oral cancer,”. Radiation therapy (RT) has been extensively used for locally advanced cancer.  The study showed that only 20-30% of tumors respond to RT. Thus, there is an unmet clinical need to identify radiosensitizers.  We have identified an epigenetic regulator, Lysine-specific demethylase 1 (LSD1), which promotes oral and resistance to RT. We expect to evaluate the novel mechanisms that LSD1 promotes DNA damage repair response signaling pathways and inhibition, which could promote sensitivity to RT using a mouse model and pathway analysis. Dr. Truong, who is clinical radiation oncologist and expert in radiation therapy who will provide help in evaluating the doses and relevance of findings for future translation.

Dialysis Modality Education Access for Latinx Individuals with Kidney Disease

Latinx people experience a two times greater risk of kidney failure compared to non-Latinx White individuals yet are less likely to receive adequate preparation for kidney failure- leading to high rates of urgent dialysis initiation and lower rates of home dialysis and transplant. Pre-dialysis kidney disease education is associated with significantly higher odds of patient-centered preparation for dialysis amongst Latinx individuals. However, Latinx people are less likely to receive adequate kidney dialysis education prior to dialysis, and are more likely to report lack of shared decision-making with their clinician. The aim of our study is to 1) qualitatively evaluate the dialysis modality education experience for Latinx people with kidney disease and their clinicians and 2) establish a community research steering committee to co-design culturally tailored dialysis modality educational materials for Latinx individuals with kidney disease.

Dr. Katherine “Katie” Rizzolo is a clinician-investigator and instructor in the Department of Nephrology at Boston Medical Center. Her research interests center on advocacy for underserved communities disproportionately affected by kidney disease, especially Latinx and immigrant populations.

In-depth Profiling of Sickle Cell Disease (SCD) Hematopoietic Stem and Progenitor Cells (HSPCs) to Advance Gene Therapy and Transplantation Approaches

The pilot proposal that was funded by the CTSI complements transformative gene therapy treatments that have recently become available to our sickle cell disease (SCD) patients at BMC. To continue to optimize such treatments and make them safer, more efficacious, and more widely accessible, we will establish a SCD-specific hematopoietic stem and progenitor cell (HSPC) signature. Sickle cell disease is associated with chronic inflammation of the bone marrow, affecting HSPCs residing in that niche. To better understand how this inflammation impacts their function and expression profile, we will perform an in-depth characterization of SCD HSPCs, combining functional, transcriptional and cell surface profiling. This work will form the basis for an updated clinical workflow, enabling more accurate stem cell quantification. This in turn will facilitate further optimizations to gene editing and transplantation procedures in terms of cost, precision and safety profile. Our proposal will also explore ways to expand functional hematopoietic stem cells ex vivo, which will be important to make these emerging cell therapies accessible to SCD patients with advanced disease where mobilizing sufficient stem cells to reach current thresholds for cell therapy can be difficult.

Naltrexone for the Treatment of Cannabis Use Disorder in Pregnancy

The primary objective of their study is to gain pilot data on the relative safety and efficacy of the use of Naltrexone (extended release; trade name: Vivitrol) (NTX) in pregnant persons with cannabis use disorder.  In this 1-year prospective cohort study, 14 pregnant people with cannabis use disorder (CbUD) (DSM-V diagnostic criteria) between 14- and 30-weeks’ gestation will be enrolled through Boston Medical Center’s Project RESPECT prenatal clinic. Cannabis use disorder (CbUD) during pregnancy impacts an estimated 6-10% of pregnant individual in the US.¹ The COVID-19 pandemic and the legalization of cannabis have contributed to increasing cannabis usage ². CbUD disproportionally impacts younger individuals of racial minorities with lower educational status, making this a particular relevant issue at Boston Medical Center (BMC).^2-3 Cannabis use during pregnancy is associated with adverse perinatal outcomes including increased risk for placental abruption, gestational hypertension, low birth weight, preterm birth, NICU admission, lower APGAR scores, and smaller neonatal head circumference.⁴ In addition, in-utero cannabis exposure may be associated with altered neonatal brain development.⁵ Further associations of cannabis use in the perinatal period include challenges in breastfeeding decision making, co-occurrence of CbUD with other substance use disorders (SUDs), and the risk for involvement of child welfare agencies.^6-7 Pregnancy is a highly motivating time for individuals to seek treatment for substance use disorders.⁸ However, there are no well-established pharmacologic treatments for CbUD that are routinely used. One emerging therapy is the medication naltrexone (NTX), which works by blocking the mu-opioid receptors thereby inhibiting the release of dopamine.⁹ This decreased activity in the mesolimbic dopamine reward pathway attenuates the positive effects of substances of abuse and the development of cravings and dependence.⁹ NTX is FDA approved as first-line treatment for alcohol use disorder (AUD), and is used increasingly for the treatment of those with opioid use disorder (OUD) with NIH studies of its use in pregnancy for OUD and AUD being led by our team at BMC.¹⁰ Cannabis acts on the endogenous cannabinoid receptors which are closely linked with the opioid receptor systems.^11-12 Prior studies in non-pregnant individuals utilizing NTX for the treatment of CbUD have hypothesized that NTX acts on both systems, upregulating opioid and cannabinoid receptors. NTX has been trialed for CbUD, demonstrating a decrease in cannabis use in non-pregnant individuals.^11,13-14However, NTX has never been trialed in pregnant individuals with CbUD who arguably have more to gain from cannabis reduction to improve maternal and neonatal outcomes.

The primary outcome measure of this study will be quantity of cannabis use, defined by survey and laboratory data assessing cannabis consumption. All key outcome measures are as follows: 1) participant outcomes [cannabis consumption, retention in care, preterm birth, and side effects / adverse events); 2) fetal outcomes (intrauterine growth, fetal anomalies).

Assessing and Addressing Implicit Bias within Healthcare-acquired Infections (AAIm HI)

Structural racism has resulted in inequities across healthcare. A 2018 report on national healthcare quality and disparities, showed marginalized racial/ethnic groups receive worse care and have worse health outcomes. Healthcare-associated infections (HAIs) are an important measure of quality and a significant cause of morbidity and mortality for hospitalized patients. High-quality studies linking racial bias and HAIs are lacking as are studies of HAI reduction initiatives that specifically target racial inequities. Reducing the incidence of HAIs is a major priority for hospitals and regulatory agencies as federal programs link financial penalties or rewards to achieving HAI benchmark improvement goals. Safety Net Hospitals, which have limited resources to implement improvements, and care for more structurally and medically vulnerable communities than other hospitals, are also more likely to incur financial penalties from those incentive programs and must find ways to improve HAI rates and address inequities. Implicit bias training is becoming more prevalent across healthcare but has not been used to specifically improve a targeted healthcare outcome. This proposal aims to reduce implicit bias in healthcare and innovate the use of implicit bias training to improve specific patient outcomes (i.e.,HAIs) impacted by racial bias.

Association between Hip Shape and Hip Symptoms

Osteoarthritis (OA) of the hip poses a substantial economic and personal burden. Structural variants in hip morphology on both the acetabular side (dysplasia) and the femoral side (cam morphology) contribute to increased risk of hip OA. However, most studies have used radiographic hip OA as the outcome measure and focused on standard measures of bone shape (i.e., center-edge angle and alpha angle). The group proposes to address this gap by capitalizing on hip structure and symptom data previously collected as part of the Multicenter Osteoarthritis (MOST) study. The group will analyze long-limb radiographs using both standard measures and statistical shape modeling (SSM) to quantify femoral and acetabular shape. The group will determine the association between hip symptoms (pain) and standard shape measures (Aim 1) and shape variations (Aim 2). Understanding this relationship is critically important as hip symptoms, not hip OA, are linked with an increased risk of all-cause mortality. The resulting knowledge gained will provide valuable information for clinicians and patients considering shape-normalizing surgery. Future studies will include obtaining three-dimensional imaging (CT or MRI scans) to overcome the present limitation of using only a two-dimensional picture (radiograph) of 3-D bone shape; notably, the outcomes of the work proposed here will be an important indicator of whether the more intensive 3-D imaging is warranted.

Determining Contributions of Hepatocyte Heterogeneity to ZZ AATD-Associated Liver Disease

Alpha-1 antitrypsin deficiency (AATD) is a common inherited cause of chronic liver disease, without any clinically-available therapies beyond organ transplantation. In the US alone, it is estimated that 100,000 individuals are homozygous for the “Z” mutation (referred to as ZZ), the most common liver disease causing variant. While all hepatocytes express SERPINA1, the gene that encodes AAT, misfolded ZAAT protein has long been recognized to differentially accumulate within the ER of specific hepatocytes which has led to the hypothesis that subsets of hepatocytes are disproportionally affected in disease. However, difficulties in accurately modeling human liver disease at single cell resolution have made it challenging to explore this hypothesis. Additionally, the lack of insight into human hepatocyte heterogeneity and the mechanisms contributing to this heterogeneity, may be critical factors limiting the suitability of human AATD-livers to be treated with future cell-based cell therapies. Dr. Kaserman and Dr. Gouon-Evans will address these clinically translatable questions, leveraging a unique set of resources available on the BU Medical Campus: Boston University is one of 3 sites nationally participating in the Alpha-1 Adult Clinical and Genetic Linkage Study and has performed liver biopsies on 23 ZZ patients over the past 2 years that will be utilized for this study. Furthermore, BU has recently invested in MERSCOPE technology that allows the interrogation of gene expression in fixed tissue samples at single cell resolution. Over the next year, this proposal will apply the first ever integrated advanced RNA sequencing approaches to these rare AATD clinical samples using complementary spatial transcriptomics and single nuclear sequencing to facilitate future therapeutic discovery, with an emphasis on improving cell therapy for this large patient population.

Individual and Neighborhood-Level Disparities in Buprenorphine Treatment Among BMC Patients

Opioid overdose deaths continue to accelerate with a disproportionate rise among individuals from racial and ethnic minority groups. In addition, individuals from racial and ethnic minority groups exhibit lower receipt of buprenorphine, a key medication in the treatment of opioid use disorder (OUD), relative to Whites. Similar patterns emerge at the neighborhood-level. For example, research has identified associations between neighborhood-level race, ethnicity and income with rates of treatment with buprenorphine and other medications for OUD (MOUD).
The disproportionate rate of opioid-involved overdose in neighborhoods of lower wealth and greater percentage Black or Latino residents demands urgent attention to the intersection of individual and neighborhood-level disparities in OUD treatment. This proposal leverages the Data 4 Equity (D4E) platform, an effort by the BU CTSI Biomedical Informatics Core to strengthen geo-spatial and health disparities research at BUMC. The proposed research aims to describe individual and neighborhood-level disparities in buprenorphine receipt for BMC patients using D4E. This proposal will generate the preliminary work needed for a larger proposal involving more robust geo-spatial analyses of disparities in buprenorphine treatment at BMC.

Pilot Feasibility Study of an In-Home, Body Weight Harness Mobility System for Infants with Down syndrome

The emergence of crawling and walking is significantly delayed in infants with Down syndrome (DS), but the development of independent mobility provides infants with new opportunities for exploring the environment and interacting with objects and people, which are important foundations for early learning. Increasing infant mobility early in development with body weight supported harness systems may support infant exploration, communication, and social interaction. This project will set the stage for the first clinical trial of a mobility-related intervention specifically tailored for infants with DS by testing the feasibility of harness systems with infants and families and identifying measures that will serve as primary outcome variables.

Risk Assessment of Lung Squamous Premalignant Lesions

Lung cancer is the leading cause of cancer death. To increase survival, therapies are urgently needed to intercept the cancer development process and decrease the rate of patients presenting with advanced disease. Lung squamous cell carcinoma (LUSC), the second most common type of non-small cell lung cancer in the US, arises in the epithelial layer of the bronchial airways and is often preceded by the development of bronchial premalignant lesions (PMLs). Approximately 10-50% of high-grade bronchial dysplasia and cases with multiplicity of bronchial dysplasia are likely to progress to invasive LUSC. Also, the presence of persistent or progressive high-grade dysplasia is a marker of increased lung cancer risk, and lung cancers may develop either at the lesion site or at a separate location. There is currently a lack of biomarkers to predict which lesions will progress to LUSC and to predict the risk of lung cancer development anywhere in the lung in patients with PMLs. Development of these biomarkers may improve lung cancer screening by identifying the optimal screening interval and modality (CT and/or bronchoscopy) as well as identify patients for and suggest effective agents for lung cancer interception. The group is currently developing deep learning frameworks using digitized H&E whole slide images (WSIs) of PMLs to predict histologic features and outcome.  In this proposal, the group will develop deep learning models using PML WSIs and clinical covariates to predict risk of a lesion progressing to LUSC and a patient-level risk of developing lung cancer.

Target Deconvolution Of Host-Directed Antiviral Rocaglates

The continued spread of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) warrants discovery of new antiviral therapeutics. To address this need, a team led by Prof. John Porco (PI, BU Chemistry BU-CMD and co-Investigator Prof. Robert Davey (BU-NEIDL) employed a cell-based screen that identified a number of synthetic rocaglates as potent inhibitors of SARS-CoV-2 infection. Rocaglates are a diverse family of plant metabolites with potent anti-neoplastic and anti-infective activities. In the CTSI Integrated Pilot Grant “Target Deconvolution of Host-Antiviral Rocaglates,” a two-phased approach will be used to identify rocaglate host targets that are important for SARS-CoV-2 infection. The approach involves use of a novel thermal proteome profiling assay to identify candidate targets of antiviral rocaglates, followed by a targeted CRISPR screen to disrupt candidate targets and evaluate impact on infection efficiency.

Benchmarking Intra-tumor Heterogeneity Approaches in Aggressive Breast Cancer

To date, there have been little to no studies to date that have mapped intra-patient tumor heterogeneity and compared how this is effectively maintained in ex vivo models in a statistically rigorous manner. Here, we aim to make usage of operational clinical pipelines and advancements in spatial, single-cell and experimental modeling techniques that we have established in our labs to address this unmet need and to quantitatively describe the levels and modeling reproducibility of intra-tumor heterogeneity in patients with aggressive breast cancer. To evaluate the significance and limitations of current state-of-the-art intra-tumor modeling approaches, we propose the following aims: 1) Map and document intra-tumor breast cancer heterogeneity using an ultra-resolved spatial multiplexing technology (MERFISH); and 2) Determine how existing patient-derived organoid models recapitulate the original TME diversity at the single-cell level. These studies are essential to safeguard our precious patient samples which are limited and can typically only be used once. Hence, a thorough understanding of the limitations on which future research conclusions or preclinical screening results are based on will be of crucial importance.

Defining a Molecular Signature of Cardiac Dysfunction in Systemic Immunoglobulin Light Chain Amyloidosis

Systemic immunoglobulin light chain (AL) amyloidosis features misfolding of destabilized light chains (LCs) produced by malignant plasma cells in bone marrow. Misfolded LCs become amyloid fibrils that deposit in target organs. Organ dysfunction leads to poorer prognosis of AL amyloidosis than other plasma cell dyscrasias. Specifically, advanced cardiac dysfunction limits treatment options and causes early mortality. Cardiac dysfunction is directly precipitated by: 1) direct effects of destabilized LCs and eventually 2) structural damage from amyloid fibril deposits. Understanding early mechanisms of cardiac dysfunction is key to developing screening methods and treatments critical to improving these outcomes. Therefore, the team seeks to identify and validate a molecular signature for early mechanisms of LC-mediated cardiac dysfunction using patient-derived LCs in a novel disease model of induced pluripotent stem cells.

Dr. Camille Edwards is an Assistant Professor of Medicine at Chobanian and Avedisian School of Medicine (BUSM) at Boston University.

The Relationship of Intra-articular Mineralization to Synovitis in Knee Osteoarthritis

Knee osteoarthritis (OA) affects a large number of adults in the United States and is a major cause of disability. Current treatments for Knee OA are limited in their ability to prevent disease progression and alleviate symptoms. The failure of OA therapies to date is partly due to not targeting the appropriate at-risk populations. Focusing on a Knee OA subtype, those with intra-articular (IA) mineralization, may lead to more effective treatment through the development of targeted mechanistic approaches. This proposal aims to investigate the relationship between IA mineralization and inflammation (synovitis on MRI) in Knee OA. The study will provide valuable insights into how IA mineralization contributes to inflammation, potentially leading to improved therapies, such as anti-inflammatory treatments, for specific groups of people with Knee OA.

Profiling of Vulnerable Neurons During the Prodromal Stage of Alzheimer’s Disease

During the early presymptomatic stages of Alzheimer’s disease, only a very specific type of neurons involved in new memory formation starts to dysfunction and form proteinaceous aggregates before degenerating. By the time the first clinical symptoms appear, a substantial number of these neurons have already died. State-of-the-art genomics technologies, such as Single-Nucleus RNA-sequencing, have revealed the molecular changes occurring in neurons at advanced stages of the disease. However, previous studies have utilized the brains of individuals who were diagnosed with Alzheimer’s and had already passed away. Dr. Roussarie, Dr. Stein, and Dr. Zhang propose obtaining brain samples from the BU Alzheimer’s disease research center, specifically from individuals with Alzheimer’s lesions who passed away before experiencing any symptoms. These samples will be analyzed using single-nucleus RNA-sequencing to identify very early disease-associated molecular events.

Improve Language Diversity in Clinical Trials

Even though many patients with limited English proficiency (LEP) can be helped through clinical trials, they are often excluded due to a lack of diverse research teams that are able to effectively engage with them. This gap in trial representation translates to a gap in treatment. Boston University School of Social Work (BUSSW) Dr. Martinez will help close this gap by testing and assessing promising engagement strategies with a grant from the Boston University Clinical and Translational Science Institute (CTSI). The CTSI Integrated Pilot Grant Program has awarded funds to study CTSI sites including Boston Medical Center, where 31% of patients report a first language other than English.

Advancing language justice in clinical trials requires an investment in systems-level change to support the intentional inclusion of LEP patients. “The enrollment and retention of LEP patients in research requires diverse research teams who are able to communicate, engage, and build trust with limited-English speaking populations,” Sprague Martinez explains. “Solutions that lead to fully representing LEP patients in research may provide increased access to specialized novel treatments only available through trials, and thus serve to bridge racial and ethnic disparities in health.” These steps will create a collection of best practices for medical institutions to adopt.

A Patient-Specific Induced Pluripotent Stem Cell (iPSC)-based Organoid Model of Pulmonary Fibrosis 

The incompletely understood pathogenesis of pulmonary fibrosis and lack of reliable preclinical disease models have been major hurdles in developing effective therapies. Emerging literature now implicates alveolar type 2 (AT2) cell dysfunction as an initiating pathogenic event in the onset of a variety of pulmonary fibrosis syndromes, including adult idiopathic pulmonary fibrosis (IPF) and childhood interstitial lung disease (chILD). However, the inability to access primary AT2 cells from patients, particularly at early disease stages, has impeded the identification of disease-initiating mechanisms. The goal of this proposal is to provide a patient-specific in vitro model system, based on induced pluripotent stem cell-derived AT2 cells that we have engineered in vitro from patients with pulmonary fibrosis associated with the most common disease-associated SFTPC variant (SFTPC^I73T), in order to uncover the mechanisms leading to human AT2 cell dysfunction, at the moment of disease inception.

HIV-1 RNA Modification as a Driver of Innate Immune Activation

HIV-1⁺ individuals on successful anti-retroviral therapy still suffer from various complications caused by chronic inflammation, but the mechanism underlying persistent inflammation is currently unclear. We have shown that expression of HIV intron-containing RNA (icRNA) in infected macrophages induces pro-inflammatory responses, however, what makes HIV icRNA immunostimulatory remains unclear. Epitranscriptional modifications in viral RNAs have been linked to various biological processes including innate immune sensing and induction of type I interferon and pro-inflammatory responses. We, therefore, hypothesize that HIV icRNAs are marked by unique base modifications, which confers immune-stimulatory capacity to HIV icRNA. To test this hypothesis, in collaboration with Dr. Daniel Cifuentes, Assistant Professor in the Department of Biochemistry, we will use two complementary approaches to quantify RNA modifications in HIV icRNA:  2D thin-layer chromatography (TLC) and nanopore sequencing (Oxford Nanopore Technologies). We will determine the quantity and position of RNA modifications in HIV icRNAs. We hope that the successful completion of this proposal will serve as a basis for a future NIH R01 grant that will focus on the roles of HIV RNA modification in innate immune responses. Ultimately, identification of HIV RNA modifications responsible for immune activation could lead to the development of novel therapeutic strategies to manage inflammation-associated complications in HIV⁺ individuals on anti-retroviral therapy.

Highly Multiplexed Immunophenotyping of Aggressive Histologic Patterns of Early-Stage Lung Adenocarcinomas

Lung cancer remains the leading cause of cancer death, in large part due to our inability to intercept the disease process prior to progression to an advanced and lethal state. We lack an understanding of the earliest targetable molecular events in lung carcinogenesis and effective strategies to identify and treat aggressive cancers. Using single-cell proteomics, via imaging mass cytometry (IMC) we will study immune cell marker expression and localization in normal tissue and adjacent LUAD with either aggressive or indolent histologic patterns that may identify biomarkers to predict the presence of aggressive cancers. The proposed study leverages a unique set of early-stage LUAD tumors with extensive pathologic characterization that may start to unravel aggressive LUAD immune changes, which has implications for lung cancer diagnosis and interception. The results of this work may suggest new lung cancer interception strategies for early-stage invasive LUAD as well as improve current clinical management and outcomes.  Our findings will serve as pilot data for a planned NIH R01 proposal.

Liver-dependent Lung Remodeling and Pneumonia Susceptibility During Sepsis

It has long been known that systemic inflammatory events, such as those inherent to sepsis, tremendously predispose patients to hospital-acquired lung infections. Yet, the biological pathways influencing lung immunity during sepsis are poorly understood. Dr. Lee Quinton’s research has now established that liver responses to systemic inflammation calibrate the immunological tone of lung tissue, increasing its capacity to respond to subsequent infections. This study will leverage liver-specific mutant mouse models and single-cell sequencing to delineate cell-specific changes within the lung that rely on intact liver function, pursuing the hypothesis that during sepsis, liver activity dictates the transcriptional fingerprint of lung cells, including alveolar macrophages, to limit pneumonia susceptibility.

Dr. Lee Quinton is an Associate Professor of Medicine, Microbiology, and Pathology. He joined the faculty in the Pulmonary Center in 2008 after completing his post-doctoral fellowship at the Harvard School of Public Health.  Dr. Quinton’s research program focuses on molecular mechanisms governing immunity and tissue protection during pneumonia. In particular, his laboratory has identified liver activation as a conduit through which early response cytokines promote local and systemic defense in response to lung infections. Additional investigations in Dr. Quinton’s laboratory are focused on deciphering signals controlling epithelial barrier integrity in the pneumonic lung, with the specific goal of determining when, where, and how lung cells collaborate to limit inflammatory injury.

Modeling the Anemia Elicited by Chronic Kidney Disease in Zebrafish

The goal of this research is to uncover how the interplay between microRNAs and uremic solutes orchestrate the responsiveness to erythropoiesis-stimulating agents (ESA) in chronic kidney disease (CKD). To this end, this project will model the anemia of CKD using zebrafish embryos as a model system. Preliminary data suggest a protective role of miR-451 in front of the oxidative stress induced by the uremic milieu. The findings from this project will have the potential to be developed into biomarkers and drug targets to enhance the precision of ESA therapeutics.

At the intersection of uremic toxicity and microRNAs, this proposal is innovative because it probes, for the first time, the effect of a set of uremic solutes on microRNA biogenesis, examines zebrafish as a model of uremic toxicity and the mechanism of ESA-responsiveness in end-stage renal disease patients. The novelty of the proposal is driven by an interdisciplinary team experienced in microRNAs and zebrafish (Dr. Cifuentes), and uremic toxicity (Dr. Chitalia).

Multimodal Microscopic Characterization of Novel Humanized Mouse Models of COVID-19

Improved animal models that faithfully recapitulate histologic phenotypes of severe COVID-19 are needed to enhance our understanding of host and viral determinants affiliated with SARS-CoV-2 pathogenesis. Current animal models fall short in that they either result in mild subclinical disease reflective of most COVID-19 cases or result in fatal neuroinvasion that is not documented in humans. In collaboration with Drs. Florian Douam (Boston University), Alex Ploss (Princeton), and Alejandro Balazs (Ragon Institute), we will microscopically characterize humanized mice engrafted with human lung xenografts in the absence and presence on concurrent human hematopoietic stem cells (dual engrafted). We will utilize a broad array of microscopic techniques including histomorphology, transmission electron microscopy, and multiplexed immunofluorescent immunohistochemistry to systemically characterize the immunopathologic landscape of these humanized mouse models. Because of the ability of our mouse model to integrate a multi-layer functional human immune response, we hypothesize this project will provide unprecedented insights into the cellular and molecular mechanisms that define SARS-CoV-2 immunopathogenesis and severe COVID-19 disease. Importantly, our findings will be integrated with transcriptomics and proteomics datasets to elucidate specific biological pathways driving morphomolecular findings. Through a better understanding of these mechanisms, this work will open significant opportunities for the development of better-targeted therapeutics and immunotherapies against COVID-19.

Patient Perspectives on Disrespect and Abuse in Maternity Care

Experiences of disrespect and abuse during childbirth in healthcare facilities have been associated with subsequent PTSD, avoidance of maternal health services, and increased risk of maternal morbidity and mortality. This global human rights issue has largely been reported in low and middle-income countries but is under-investigated in the United States and Europe. Limited data on women’s experiences in the United States indicate meaningful rates of disrespect and abuse, with significant racial and ethnic disparities. Given the disproportionately increasing rates of pregnancy-related mortality and severe morbidity among minoritized racial groups in the United States, it is imperative that we understand the factors and specific behaviors that contribute to these experiences of disrespect and abuse during maternity care. This study will use mixed methods to assess the prevalence and experiences of disrespect and abuse among women delivering at Boston Medical Center (BMC). Our findings will serve as pilot data for a planned March of Dimes grant.

Role of ZEB2 in Pericytes Development and Renal Fibrosis

The goal of this pilot grant is to elucidate the role of ZEB2 in kidney fibrosis. ZEB2 is a SMAD-interacting transcriptional factor and is expressed in Foxd1⁺ stromal cells that are progenitors for pericytes and fibroblasts during kidney development. Pericytes and fibroblasts are the key cell types contributing to the myofibroblasts during kidney fibrosis. We will analyze the histopathological changes in the kidneys of Zeb2 stromal-specific conditional knockout mice (Zeb2^flox/flox; Foxd1^Cre+) which developed kidney fibrosis. The outcome of this project will help understand the cellular and molecular mechanisms of kidney fibrosis and pericyte/fibroblast development.

SARS-CoV-2 Diversity and Transmission Among Healthcare Personnel

Healthcare personnel (HCP) have been disproportionately affected by severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), however little is currently known about where and under what conditions SARS-CoV-2 transmission occurs in clinical settings. This study will combine viral whole-genome sequencing with rich epidemiological and contact tracing data on a unique cohort of healthcare workers and nosocomial patient cases spanning the initial COVID-19 surge in Boston. With a team of experts from Boston Medical Center, Boston University School of Public Health, and the Boston University National Emerging Infectious Diseases Laboratory, we aim to uncover how SARS-CoV-2 transmission in the hospital setting was successfully extinguished and identify circumstances where outbreaks persisted. A better understanding of SARS-CoV-2 transmission dynamics among healthcare workers and their patients will provide essential information for limiting hospital transmission in the ongoing pandemic.

Soft Robotic Technologies Enabling Safe Laparoscopic Bowel Manipulation

Laparoscopy is a minimally invasive technique to perform abdominal surgery through multiple small incisions in the abdomen. While this technique provides considerable advantages to the patient, it introduces several challenges to the surgeon that needs to carry out complex procedures with simple surgical tools, consisting of a long shaft with a distal end effector.
This becomes critical when manipulating delicate anatomical structures and can negatively affect the outcome of a procedure as well as the range of tasks that can be performed. Issues in laparoscopically manipulating delicate organs are caused by: 1) the inadequacy of tools in terms of dexterity and lack of compliance; and 2) the inability to sense applied mechanical stress.
This project’s endpoint will be the development of a soft atraumatic tissue manipulator for laparoscopic retraction of the bowel by exploiting soft robotic technologies. Safe and effective endoluminal tissue manipulation will be guaranteed by the design and constituent materials used for the construction of the manipulator, and through integrated pressure sensing elements that will monitor the interaction with tissues.
The proposed work will be carried out in collaboration with Donald Hess, MD, (Co-PI) Assistant Professor of Surgery, Boston University School of Medicine, Chief, Section of Bariatric Surgery, and Director of the Bariatric Surgery Program.

Validating the Role of Extracellular Matrix Molecules in Parkinson’s Disease Using Mass Spectrometry Glycomics and Proteomics

Brain extracellular matrix (ECM) consists of hyaluronan, glycosaminoglycans (GAGs), proteoglycans (PGs), glycoproteins, and a variety of post-translational remodeling proteases. GAGs and PGs play intricate roles in neuronal processes, including axonal growth/degeneration, synaptic plasticity, and neurite outgrowth in neurodegenerative disorders, including schizophrenia, Alzheimer’s disease, and Parkinson’s disease (PD). Importantly, ECM networks modulate axonal growth/degeneration and synaptic dysfunction that contribute to PD.  Thus, ECM abnormalities may denominate the dysregulation of these processes in PD. However, despite the apparent importance of the ECM molecules to neurodegeneration, little information is available on the levels and structural alterations of these molecules in ECM of PD brains. A relatively low number of mass spectrometry-based proteomics and glycomics studies have been reported for PD. Thus, this modality for identifying PD-associated targets and pathways remains under-explored for understanding underlying PD pathophysiology.

We assessed the structural alterations of GAGs and proteins in the human PD brain prefrontal cortex relative to controls in two separate cohorts using ultra-high-performance mass spectrometry proteomics and glycomics technology. We identified alterations to GAG structure and enrichment of ECM constituents in the PD brain. This is the most extensive glycomics and proteomics study on PD to date. For any cohort-based study, the only way to eliminate all possible sources of bias related to tissue procurement and processing is to repeat the work using separate biospecimen cohorts in future studies. Thus, we will validate these findings using two new cohorts similar to our previous work, consisting of 12×12 PD and age-matched non-neurological disease controls, instead of one large validation cohort, because of various challenges associated with increasing sample size, including degrading quantitative quality, snowballing missing data and false‐positive discovery of altered proteins. For this study, we will refine our data quality control and acquisition to enhance our ability to assess the findings of our previous study. Our unbiased and nuanced view of alterations of ECM glycans, proteins, and genes will solidify our knowledge of PD pathology and uncover targets for more effective and preventive therapeutic strategies.

We will conduct this work at the BU Center for Biomedical Mass Spectrometry, where Dr. Sethi (PI of the project) works as an Instructor. The biospecimens will be provided by Dr. Thor D. Stein, a neuropathologist at the BU-VA-CLF Brain bank, who will serve as a Co-PI on the project.

Lionoleic Acid Promotes Pathogenic T Cells in Type 1 Diabetes 

Type 1 Diabetes is an autoimmune disease caused by T cells that destroy the insulin-producing beta-cells in the pancreas. The incidence of Type 1 Diabetes is rapidly rising worldwide due to currently unknown environmental factors that promote the autoimmune response in genetically susceptible individuals. There is growing evidence that specific metabolites derived from the diet or microbiome have the capacity to influence the functions of T cells and may promote pathogenic T cells in autoimmune diseases. We discovered that addition of the dietary fatty acid linoleic acid to in vitro T cell cultures altered the balance between pathogenic IL-21-producing and protective IL-10-producing T cell subsets in favor of the cells with pro-diabetic activities. The goals of this CTSI pilot grant are to test whether autoreactive T cells exposed to linoleic acid have an increased capacity to cause diabetes in vivo, and whether feeding diabetes-susceptible NOD mice a linoleic acid-rich diet will accelerate diabetes development. Our study has the potential to identify a dietary factor that is increasingly present in Western diets as a driver for increased Type 1 Diabetes susceptibility. This finding may form the basis to develop preventative dietary interventions in susceptible individuals and/or to target the metabolic and signaling pathways that underlie linoleic acid-based induction of diabetes-causing T cells.

Primary Care Connection in Maine

Millions of Americans have gained health insurance under the Affordable Care Act’s Medicaid expansion. However, health insurance is only a first step toward the goal of improving population health; receipt of primary care is a critical follow-up step. Despite the array of known benefits of primary care, little empirical work has examined how states can encourage uptake of primary care among new Medicaid enrollees. To address this gap in the evidence, we propose to design and pilot test an intervention to increase engagement with primary care services among newly enrolled Medicaid beneficiaries in the state of Maine, in partnership with the Office of Member Services (OMS) at the Maine Department of Health and Human Services. The pilot study will be a single blinded, randomized, controlled trial of a behavioral intervention to increase the PCP visit rate within the first six months of new Medicaid enrollment. The treatment arm will receive a one to two page letter that encourages new enrollees to get a free checkup and recommends a single provider, located within 30 miles of the enrollee’s home address. Clinics will be notified of newly assigned patients and encouraged to reach out to schedule initial appointments. The control arm will receive the current MaineCare enrollee packet of 23-pages, including a comprehensive provider directory. We will assess acceptability and feasibility of our intervention to MaineCare members, providers, and our partners at OMS. If the pilot trial proves acceptable and feasible, we will plan to implement a larger scale trial within 6 months of the pilot’s end.

A Tool to Identify PrEP Eligible Youth in Primary Care

Pediatricians are the most common provider of primary care for youth, and frequently provide care to individuals through their early-to-mid 20s. Thus, pediatric primary care offers an opportune setting for identifying youth who are eligible for pre-exposure prophylaxis (PrEP). To successfully identify PrEP-eligible youth, it is essential that pediatricians ask valid, developmentally appropriate screening questions that resonate with youth and elicit accurate information. The objective of this proposal is to conduct mixed methods, translational research to develop (Aim 1), and conduct a pilot study (Aim 2) of a HIV risk assessment tool that pediatricians can integrate into their current primary care practice to identify PrEP-eligible youth. Data from the pilot study will directly inform a subsequent clinical trial of a comprehensive PrEP service delivery model for pediatric primary care.

Influenza Induced Lymphangiogenesis 

The overall objective of this proposal is to identify lymphatic-centered strategies to contain viral lung  infections. To achieve this goal, the PIs use a mouse influenza model that allows for deciphering the functional therapeutic properties and origins of the markedly expanded pulmonary lymphatic system that the PIs found accompanies influenza.  Based on preliminary data, the central hypothesis is that new lymphatic growth facilitates immunomodulatory events and alterations in lymphatic cell function that are central to virus containment.  The PIs propose to use the CTSI pilot grant to perform a detailed transcriptional analysis of lymphatic cells as the lung responds to influenza.

The PIs driving this project are Dr. Matthew Jones and Dr. Alan Fine. Together, they have a successful history of collaboration on various projects, grants, and papers.

Dr. Matthew Jones is a lung molecular biologist with an extensive history of studying the lung’s response to infection.  Dr. Jones also brings a deep knowledge of gene expression analytical methodology to this project.

Single-Cell Analysis of AL Amyloidosis Plasma Cells

Since starting at BUSM in 2018, Gareth has established a program to study the aberrant plasma cells that underlie AL amyloidosis, which is a rare but often fatal form of systemic amyloidosis. These plasma cells normally secrete antibodies as part of the adaptive immune system. Aberrant proliferation in bone marrow causes overproduction of antibodies and, in some cases, amyloidosis. Comparing the gene expression of these cells to that of healthy plasma cells and those from a related disease, multiple myeloma, should reveal specific vulnerabilities that can be targeted for therapy. The CTSI pilot grant will enable researchers from the Amyloidosis Center to measure single-cell gene expression profiles of primary cells isolated from patient bone marrow aspirates. This project brings together the clinical work of the BU Amyloidosis Center with the cutting-edge instrumentation in the Department of Medicine Single Cell Sequencing Core Facility. These experiments will enable larger-scale studies to identify therapeutic targets and prognostic markers that could help to optimize treatments and benefit patients.

Gareth Morgan is a Research Assistant Professor in the Section of Hematology and Medical Oncology at the Boston University School of Medicine, and a member of the BU Amyloidosis Center. Originally from the United Kingdom, Gareth completed his B.Sc. in Biochemistry from Imperial College, London.

Gareth worked as a postdoctoral research associate with Professor Sheena Radford at the University of Leeds, and then with Professor Jeff Kelly at the Scripps Research Institute in San Diego, CA. Throughout his career, Gareth has studied how proteins fold, misfold and aggregate. He is especially interested in understanding how cells and organisms manage and maintain their proteomes, and why these processes break down to cause systemic amyloidosis diseases, where accumulation of protein aggregates leads to progressive organ failure. A major research focus is on developing small molecule drugs that can prevent protein aggregation, which could benefit patients with these diseases.

Machine Learning Risk Stratification of Stroke in Patients with AF

We aim to develop a clinically-oriented risk prediction model of stroke in patients with non-valvular atrial fibrillation using novel, clinically-oriented machine learning methods and data from Boston Medical Center and the UK Biobank

Non-valvular atrial fibrillation (NVAF) is associated with a five-fold increased risk of stroke.¹ The most widely used prediction scales to risk stratify patients include the CHADS₂²,CHA₂DS₂-VASc³, and Framingham Risk scales.^1,4 These are commonly used to guide management decisions (anticoagulation or antiplatelet therapy) for primary or secondary stroke prevention. However, like many risk prediction scales, they assume that the addition of risk factors is cumulative and linear,⁵ which limits their discrimination (C statistics of 0.68-0.7 in large validated studies)^6,7 and generalizability. Advances in machine learning (ML) methods allow us to model non-linear risk in large datasets, improving performance, making individualized risk stratification possible. Moreover, our group has developed a novel and interpretable tree-based ML method specifically tailored for clinical applications. Optimal classification trees (OCTs) is an ML method that improves accurate classification compared to traditional statistical methods, while allowing practitioners to easily identify risk factors that contribute to outcomes.⁸ Such interpretability resolves the “black-box” or opaque classification disadvantage intrinsic to using many ML techniques. Our group has used these methods to stratify patients at high risk for emergent surgery, to predict 10-year cardiovascular risk, and to make treatment recommendations in diabetic patients.^5,9,10 ML methods have not yet been used to develop clinically-oriented risk prediction models in cerebrovascular diseases like stroke risk in patients with atrial fibrillation (AF). We propose an innovative approach using a variety of novel, OCT-based methods to improve personalized stroke risk stratification in patients with non-valvular AF. Improved risk stratification would profoundly impact the population’s cardiovascular health, as it can inform management for approximately 5.3 million Americans with AF.¹¹

Soft Robotic Platform for Restoring Haptic Feedback in Robotic Surgery

Robotic surgery has improved minimally invasive surgical procedures and shortened learning curves for surgeons. However, during robot-assisted procedures, haptic feedback is not available to the surgeon, resulting in uncontrolled force application which can lead to intraoperative complications. Absent haptic feedback is reputed to be among the reasons that impede further spread of surgical robots.
The capability to sense and touch the anatomy realistically has the potential to increase safety and precision during robotic surgery, with better patient outcomes. In this proposal, we will focus on restoring haptic feedback in minimally invasive robotic surgery by developing a soft robotic platform consisting  of a soft sensing unit, to monitor forces exerted during surgical tasks and transduce this information to a soft actuation unit, that will map tactile information back to the surgeon.

Pre-Clinical Validation of Novel Gene Editing Approaches for Sickle Cell Disease

With the support of the CTSI pilot grant, Dr. Vanuytsel will further develop the sickle cell disease (SCD)-specific iPSC platform as a pre-clinical tool to validate the efficacy of novel therapeutic gene editing strategies across a diverse SCD patient population.

Although SCD patients all share the same point mutation in the beta globin gene, the surrounding genetic background determines the severity of their disease course and response to therapy. Currently, several gene editing strategies are being explored as potentially curative approaches in clinical and pre-clinical trials. While these developments are truly exciting, their safety and efficacy will require thorough validation across a variety of SCD backgrounds to make sure that an effective treatment can be assured for every patient. iPSCs present an unlimited source of material that can be differentiated into erythroblasts that capture the exact genetic background of a patient, and thus make an excellent screening tool that could help predict the safety and efficacy of a particular therapeutic approach in a given genetic background prior to engaging in costly and invasive treatments.

Kim Vanuytsel is a Research Assistant Professor in the Division of Hematology and Medical Oncology at Boston University School of Medicine and the Center for Regenerative Medicine (CReM). She obtained a PhD in Stem Cell and Molecular Medicine from the Katholieke Universiteit Leuven (KULeuven) in Belgium. As a postdoc in Dr. George J Murphy’s lab, she developed novel resources and tools to better understand and treat blood disorders. Her current research focuses on finding better solutions for sickle cell disease (SCD) patients by using patient-specific induced pluripotent stem cells (iPSCs) as a versatile platform to study the disease, screen for compounds that can ameliorate the condition, and explore potential curative gene editing approaches.
