“I’m Calling CPS”: Stigma surrounding postpartum mental health conditions
Presenters
Danielle Cooke, PhD Candidate
Rebecca Henderson, MD-PhD
Mentors
Joseph McNamara, PhD
Peter Collings, PhD
Description
Stigma is commonly cited as a barrier to mental health treatment seeking in the postpartum. However there has been limited research into stigma surrounding postpartum depression, and no studies examining stigma in postpartum psychosis and obsessive-compulsive disorder. The present study examines reported social distance, fear, perceived dangerousness, and danger to a child when presented with a hypothetical mother experiencing a postpartum mental health condition in a nationally representative sample.

Habibeh Khoshbouei, PhD, PharmD
Description
Early clinical trials to treat patients with Parkinson’s Disease via intracranial administration of glial cell-derived neurotrophic factor (GDNF) have led to promising results including improvements in motor symptoms and increases in striatal dopamine storage. However, some patients experienced a plethora of adverse and toxic side-effects that were largely attributed to GDNF diffusion away from the target CNS tissue site. Here we present a strategy to restrict the diffusion of GDNF and improve bioactivity half-life at its intended target by endowing it with binding affinity for carbohydrates that are abundant on the cell surface and matrix via its fusion to the carbohydrate-binding protein galectin-3 (Gal3).

Mentors
Leslie Parker, PhD, APRN, FAAN
Graciela Lorca, PhD
Description
Often an ample supply of recently expressed or frozen mother’s own milk (MOM) is not available due to the logistics of mother’s visits or insufficient milk supply requiring the preterm infant to be supplemented with donor human milk (DHM). DHM is pasteurized, therefore lacking live commensal bacteria. This study explores the personalization of MOM through comparing fresh and frozen mother’s milk over time as an agent to inoculate DHM to obtain enriched commensal microbes similar to MOM.

A TL1 Team Approach to Identify Factors Affecting Rural Tobacco Users’ Participation in Research
Presenters
Rachel Damiani, M.A., PhD Candidate
Neo Gebru, MS, PhD Candidate
Mentors
Janice Krieger, PhD
Robert Leeman, PhD
Description
By interviewing rural tobacco users about their experiences engaging with research, we aim to better understand their unique challenges to ensure future research efforts are generalizable, rigorous, and representative of a diverse geographic population. Initial findings suggest that rural tobacco users have an overall positive perception of research, and many choose to participate in research for altruistic reasons (i.e. they want to help others). Further, participants noted described feeling stigmatized due to their tobacco use. Although most began smoking to fit in with their community, many now feel on the outs. Participants also reported logistical barriers to participating in research, including lack of transportation. Findings can inform the development of recruitment materials to resonate with rural adults, including by emphasizing the collective potential to help by participating. This interdisciplinary study highlights areas for collaboration to enhance the reach of health education and public health messages.

A TL1 Team Approach on Predicting short-term and long-term effects of spinal cord stimulation: implications for clinical practice
Presenters
Rachel Judy, PhD Candidate
Kyle See, PhD Candidate
Mentors
Stephen Coombes, PhD
Ruogu Fang, PhD
Spinal cord stimulation (SCS) is an intervention for patients with chronic back pain. Technological advances have led to renewed optimism in the field, but mechanisms of action in the brain remain poorly understood. Our work will utilize traditional machine learning methods such as support vector machine and more complex models including deep learning to generate interpretable features within resting EEG signals. Through machine learning, we anticipate that SCS will have a significant effect on resting alpha and beta power in the sensorimotor cortex. Our collaborative project seeks to further the application of machine learning in cognitive neuroscience and allow us to better understand how therapies for chronic pain alter resting brain activity.

Longitudinal profiling of the gut microbiome during and after rifamycin-based therapy for latent tuberculosis infection
Presenter
Marie Nancy Séraphin, PhD
Mentors
J. Glenn Morris, Jr., MD
Michael Lauzardo, MD
Description
The anti-TB drug rifampicin (RMP) exhibits highly variable serum concentration curves in different population groups, thus affecting TB treatment efficacy. Annually, 600,000 people develop resistance to RMP. There is a growing list of drugs whose pharmacokinetic properties are modified by the gut microbiota. However, our knowledge of the possible impact of biotransformation by gut microbiota on RMP exposure dose is limited. This KL2 project investigates anti-TB drug-induced changes in the gut microbiota and the effect on RMP exposure dose during latent TB therapy.

Hectd3 promotes pathogenic Th17 lineage through Stat3 activation and Malt1 signaling in neuroinflammation
Presenter
Jonathan Cho, PhD
Mentor
Dorina Avram, PhD
Description
Polyubiquitination promotes proteasomal degradation, or signaling and localization, of targeted proteins. Here we show that the E3 ubiquitin ligase Hectd3 is necessary for pathogenic Th17 cell generation in experimental autoimmune encephalomyelitis (EAE), a mouse model for human multiple sclerosis. Hectd3-deficient mice have lower EAE severity, reduced Th17 program and inefficient Th17 cell differentiation. However, Stat3, but not RORγt, has decreased polyubiquitination, as well as diminished tyrosine-705 activating phosphorylation. Additionally, non-degradative polyubiquitination of Malt1, critical for NF-κB activation and Th17 cell function, is reduced. Mechanistically, Hectd3 promotes K27-linked and K29-linked polyubiquitin chains on Malt1, and K27-linked polyubiquitin chains on Stat3. Moreover, Stat3 K180 and Malt1 K648 are targeted by Hectd3 for non-degradative polyubiquitination to mediate robust generation of RORγt+IL-17Ahi effector CD4+ T cells. Thus, our studies delineate a mechanism connecting signaling related polyubiquitination of Malt1 and Stat3, leading to NF-kB activation and RORγt expression, to pathogenic Th17 cell function in EAE.

Functional Neural Changes in Response to Head-Down Tilt Bedrest with Elevated CO2 During a Sensorimotor Dual Task
Presenter
Aditya Mahadevan, BS
Mentor
Description
Spaceflight and microgravity cause well-characterized changes in sensory weighting processes, central fluid distribution, and musculoskeletal structure and it is important to assess how these changes affect our ability to integrate sensorimotor information. Ground-based spaceflight analogues incorporating 6° head-down tilt bedrest (HDBR) are often used to simulate microgravity and its associated physiological changes but, recently, it has been hypothesized that combining HDBR with elevated carbon dioxide (CO2) might better mimic the conditions of a closed environment like the International Space Station. Dual task cost is a sensitive indicator of change in central motor function, and one that is affected by HDBR. Here, we examine how a 30-day HDBR intervention, including 0.5% ambient CO2, changes human performance and functional brain activity during single and dual task conditions. The task involved three phases in which participants i) counted the number of times an oddball stimulus was presented among distractor stimuli; ii) tapped one of two buttons in response to a visual cue at a rate of 1 Hz; and iii) performed both tasks concurrently. 11 participants (6 males) underwent functional MRI (fMRI) during the task: twice prior to HDBR+CO2, twice during HDBR+CO2, and twice following HDBR+CO2, allowing us to assess changes with HDBR+CO2 as well as subsequent recovery. Behavioral measures included reaction time and tapping accuracy during both the tapping and dual conditions, as well as counting accuracy during the counting and dual conditions. fMRI data were evaluated at an uncorrected p<.001. These exploratory analyses revealed areas following varying patterns of change and recovery, with some regions displaying only an initial change with the intervention while other regions displayed a dose-dependent effect. Across all task conditions, changes were found in the precentral, postcentral, and superior frontal gyri, all areas associated with sensorimotor or cognitive functions. Patterns of activation change as they correlate with behavioral change differed by task condition. The tapping condition showed better accuracy/shorter reaction time with more activation, but the dual task condition showed a more compensatory pattern. When compared to our previous HDBR investigation, we found that the increased ambient CO2 may have altered patterns of activation change seen throughout the brain. Together, these findings provide information about the additional and/or interactive effects of CO2 administration with HDBR and about how spaceflight conditions may impact the brain’s ability to maintain function during sensorimotor interference.

Using a novel neonatal mouse model to identify determinants of norovirus virulence
Presenter
Emily Winesett Helm
Mentor
Description
Norovirus is the leading cause of severe childhood diarrhea globally and a leading cause of acute gastroenteritis for individuals of all ages. Despite its clinical relevance, very little is known about the pathogenic mechanisms underlying norovirus-induced disease. The use of the murine norovirus (MNV) model system has greatly increased our understanding of norovirus biology; however, the absence of symptoms in immunocompetent adult mice limits its utility in understanding mechanisms of disease. We recently discovered that genetically wild-type neonatal mice develop acute, self-resolving diarrhea upon infection with acute MNV-1, a disease course mirroring human norovirus pathogenesis. By using this novel neonatal mouse model, we have now been able to investigate the pathophysiological mechanisms and key cellular targets of norovirus-induced disease.

Hugh Fan, PhD
Description
Osteosarcoma (OS) is the most common primary bone tumor and the third leading cause of pediatric cancer deaths. Approximately, 80% of patients will present with metastasis, however only 20% of these cases are clinically detectable at diagnosis. Current imaging modalities can only detect tumor masses of a significant size. Our group has identified novel biomarkers that can detect circulating tumor cells (CTCs) in patients. Future studies are aimed to monitor CTCs in patients over the course of their treatment and determine if there is a correlation between CTCs present and their clinical outcome.

Hippocampal Transcriptomic Profiles Reflect Strategy Selection During Cognitive Aging
Presenter
Garrett Smith
Mentor
Description
Cognitive impairment is associated with differential regulation of genes linked to specific neural systems. Previous studies, however, have not identified links between behavior and transcription in the dentate gyrus. We employed a behavioral task designed to emphasize dentate function, and correlated performance on the task to transcription in the DG. We confirmed differential regulation of synaptic and neurogenesis genes in the dentate that were related to impaired performance on this putative test of dentate function in middle-age animals. This differential gene regulation may relate to the emergence of impaired hippocampal-dependent cognition with age.

Pglyrp3, a novel critical regulator of breast cancer development and metastasis
Presenter
Mathew Sebastian
Mentor
Description
Though breast cancer mortality has decreased by ~40% over the past several decades, most of this improvement is within treatment of patients diagnosed with stages I-III of breast cancer. The metastatic stage IV breast cancer, however, continues to be a major life-threatening disease with little improvement in overall survival. Thus, a better understanding of the basic processes of cancer progression and eventual metastasis formation is needed with the therapeutic goal of metastasis prevention. However, identifying new targetable factors has proven elusive. Through computational analysis of RNA-Seq data generated using a spontaneous breast tumor forming murine model, peptidoglycan recognition protein 3 (Pglyrp3) was predicted to be a major regulator of breast cancer metastasis; however, it has never been described in the context of breast cancer. To determine the role of Pglyrp3 in breast cancer, we tested the genetic requirement for Pglyrp3 in breast tumor progression using cell line and mouse models of triple negative breast cancer and luminal invasive ductal carcinomas, respectively. Here, we describe the identification of Pglyrp3 as a novel breast cancer factor that plays an essential role in breast cancer progression. Using the 4T1 triple negative breast cell line in an orthotopic model, we found loss of Pglyrp3 leads to decreased tumor volumes (P<.001) and lung metastases (P<.0001) as compared to scrambled control in both immunocompetent and immunocompromised models. We then validated these observations and found that when isolated primary tumors from luminal MMTV-PyMT invasive ductal carcinoma with and without Pglyrp3 were implanted into immunocompromised mice, Pglyrp3-KO tumors were significantly smaller in size (P<.0001) with decreased lung metastases (P<.01). To assess whether the initial stages of metastasis and epithelial-to-mesenchymal transition (EMT) are rate limiting with Pglyrp3 deficient cells, we bypassed the initial stages of EMT by injecting Pglyrp3 deficient cells intravenously and found that they were able to metastasize equally as well as control cells suggesting that Pglyrp3 regulates the initial stages of EMT. Together, these data demonstrate a new role for Pgylrp3 as a novel regulator of breast cancer progression.

Sexual harassment experiences across the academic hierarchy
Presenter

Connie Mulligan, PhD
Environments that fortify power dynamics are more likely to foster and sustain sexual harassment. Current estimates suggest there is little difference in prevalence of experiences in medical students, residents, and faculty. However, it remains unclear how recall bias and differences in time queried impact these numbers. We surveyed trainees and faculty within the same institutional culture about sexual harassment experiences in 2018. We found a consistent trend whereby medical students were most likely and faculty were least likely to experience sexual harassment.

Tau Phosphorylation of Ser208 Promotes Aggregation of Wild Type tau in Alzheimer’s disease and Other Tauopathies
Presenter
Yuxing Xia, BS
Mentor
Description
Tau protein abnormally aggregates in tauopathies, a diverse group of neurologic diseases that includes Alzheimer’s disease (AD). In early stages of disease, tau becomes hyperphosphorylated and mislocalized, which can contribute to its aggregation and toxicity. Supporting the involvement of pSer208 in tau pathology, a novel monoclonal antibody 3G12 specific for tau phosphorylation at Ser208 revealed strong reactivity of tau inclusions in the brains of PS19 and rTg4510 transgenic mouse models of tauopathy. 3G12 also labelled neurofibrillary tangles in brains of patients with AD but revealed differential staining compared to CP13 and 7F2 for other types of tau pathologies such as in neuropil threads and neuritic plaques in AD, tufted astrocytes in progressive supranuclear palsy and astrocytic plaques in corticobasal degeneration. These results support the hypothesis that tau phosphorylation at Ser208 strongly contributes to unique types of tau aggregation and may be a reliable marker for the presence of mature neuronal tangles.

Todd E. Golde, MD, PhD
Description
Central Corticotropin family signalling as well as activation of the HPA-Axis results in significant alterations in metabolic, immune, and gene regulatory function. Targeting these pathways to modulate treatment for chronic disease, either as a monotherapy or as a treatment adjuvant, has emerged as a promising avenue in neurodegenerative, metabolic, and potentially oncologic paradigms. We have developed a monoclonal antibody that targets Corticotropin Relasing Hormone (CRH) for use as both a therepuetic intervention and a research tool to further explore the role of stress metabolism in the progression of chronic disease and behavior.

Visual Mismatch Negativity and Structural Connectivity in Hoarding Disorder
Presenter
Binh Nguyen, BS
Mentor
Description
Hoarding disorder (HD) is a psychiatric illness characterized by difficulty and distress with discarding items of minimal value and accumulation of clutter that reduces quality of life and functional use of living spaces. Because HD was only recently defined as a distinct disorder in the DSM-5, we lack a full understanding of its underlying neurobiology. Thus our group is studying visual mismatch negativity, an EEG waveform reflecting environmental change detection/perceptual accuracy that may be impaired in HD, as well as probing structural brain changes via neuroimaging that could serve as objective biomarkers and correspond to HD symptomatology and severity.
