Substance use disorder (SUD) significantly increases the risk of neurotoxicity, inflammation, oxidative stress, and impaired neuroplasticity. The activation of inflammatory pathways by substances may lead to reactive astrogliosis and chronic neuroinflammation, potentially mediated by the release of extracellular particles (EPs), such as extracellular condensates (ECs) and extracellular vesicles (EVs). These particles, which reflect the physiological, pathophysiological, and metabolic states of their cells of origin, might carry molecular signatures indicative of SUD. In particular, our study investigated neuroinflammatory signatures in SUD patients by isolating EVs from the dorsolateral prefrontal cortex (dlPFC) Brodmann's area 9 (BA9) from postmortem subjects. We isolated BA9-derived …

Background: Pulmonary hypertension (PH) is a progressive cardiopulmonary condition associated with increased morbidity and mortality. The extracellular matrix component hyaluronan (HA) is linked to vascular remodelling and interstitial fibrosis in PH. We hypothesised that inhibition of HA synthesis with hymecromone could serve as a reverse-remodelling therapy in PH.

Methods: We performed a proof-of-concept phase IIa randomised, double-blind, placebo-controlled study in adults with pulmonary arterial hypertension and PH associated with interstitial lung disease (PH-ILD). Patients were randomised to a 5:3 ratio and stratified by PH group to receive oral hymecromone or placebo two times per day over 24 weeks. The primary …

A Chronic Acinetobacter Baumannii Pneumonia Model To Study Long-Term Virulence Factors, Antibiotic Treatments, And Polymicrobial Infections, Clay D Jackson-Litteken, Gisela Di Venanzio, Manon Janet-Maitre, Ítalo A Castro, Joseph J Mackel, Leslie D Wilson, David A Rosen, Carolina B López, Mario F Feldman

2020-Current year OA Pubs

Acinetobacter baumannii causes prolonged infections that disproportionately affect immunocompromised populations. Our understanding of A. baumannii respiratory pathogenesis relies on an acute murine infection model with limited clinical relevance that employs an unnaturally high number of bacteria and requires assessment of bacterial load at 24-36 h post-infection. Here, we demonstrate that low intranasal inoculums in tlr4 mutant mice allows for infections lasting at least 3 weeks. Using this "chronic infection model" we determine the adhesin InvL is a virulence factor required during later stages of infection, despite being dispensable in the early phase. We also demonstrate that the chronic model enables …

Beyond Smoking: A Geospatial Investigation Of Factors Associated With Lung And Bronchus Cancer Risk In Pennsylvania, Tesla D. Dubois, Daniel Wiese, Kevin A. Henry, Shannon M. Lynch

Kimmel Cancer Center Faculty Papers

INTRODUCTION: While smoking is the leading cause of lung and bronchus cancer (LBC), additional exposures have been implicated and may explain the rise in LBC among never-smokers. To better understand the spatial distribution of LBC incidence and associated risk factors, this study aims to identify geographic areas with significantly elevated incidence rates in Pennsylvania and investigate the potential underlying risk factors.

METHODS: Using cancer registry data aggregated to the census tract level, spatial scan statistics were applied to detect areas of higher-than-expected LBC incidence across the state. Associations were then tested between census tract inclusion in a high-incidence area and …

Steatotic liver disease (SLD), which is associated with increased risk of cancer-related mortality, needs timely and cost-effective detection. Although liver biopsy remains the diagnostic gold standard, its invasiveness and high-cost limit widespread use. Ultrasound is a practical and affordable alternative. We evaluated inter- and intra-observer agreement for ultrasound-based diagnosis of SLD using images from the Chile Biliary Longitudinal Study (Chile BiLS), a cohort of women with gallstones. These women have a high burden of obesity and related metabolic disorders, putting them at higher risk for SLD. A radiologist (observer 1) reviewed a randomly selected subset of 425 baseline images and …

PURPOSE: Cancer treatment has been revolutionized by immune checkpoint inhibitors (ICI). However, a subset of patients do not respond and/or they experience significant adverse events. Attempts to integrate reliable biomarkers of ICI response as part of standard care have been hampered by limited generalizability. We previously reported our supervised machine learning (ML) model in a retrospective cohort of metastatic melanoma.

EXPERIMENTAL DESIGN: In this study, we expanded our testing to include larger cohorts of patients with melanoma accrued at several sites, including patients enrolled in clinical trials in both adjuvant and metastatic settings. We examined pretreatment hematoxylin and eosin slides …

Cortical Spectral Dynamics Of Vibrotactile Frequency Processing, Nabi Rustamov, Phillip Demarest, Zhuangyu Han, Safia Mohamud, Simon Haroutounian, Eric C Leuthardt

2020-Current year OA Pubs

While scientific research has extensively explored how the brain integrates touch and pain signals, the cerebral processing of specific vibrotactile frequencies remains poorly understood. This gap is particularly significant given clinical evidence that vibrotactile stimulation can reduce pain in both chronic pain patients and experimental settings. Our study investigated the cortical electrophysiological correlates of peripheral vibrotactile stimulation across different frequencies in healthy volunteers, with a focus on frequency-dependent patterns of neuronal activation. While electroencephalogram (EEG) was recorded, healthy participants received vibrotactile stimulation (high-frequency burst stimulation with different inter-burst intervals) to the left index fingertip at frequencies corresponding to established neural …

Male Caregiving Experience Alters Hippocampal Neuroplasticity And Transcription Independent Of Reproduction In A Biparental Species., Maria E Colt, Priyanka Agarwal, Erica R Glasper, Heidi Fisher

Faculty Research 2025

In mammals, measurable changes in brain and behavior accompany the transition to parenthood. In the biparental California mouse, Peromyscus californicus, fathers experience enhanced neuroplasticity, including increased hippocampal dendritic spine density, reduced anxiety, and improved memory. Here, we first investigate whether siring offspring or pup interaction drives structural neuroplasticity in fathers and find that hippocampal spine density is positively associated with caregiving experience, even in the absence of reproduction. Next, we evaluate the transcriptional response to caregiving in the hippocampus of these males and identify 158 differentially expressed genes between fathers and non-fathers, many of which are associated with neurogenesis, neuronal …

Background: Aneurysmal subarachnoid hemorrhage (aSAH) is notoriously known for its high mortality and morbidity. Approximately one-third of the patients who survive aneurysm rupture are reported to develop delayed cerebral ischemia (DCI), which contributes to a poor clinical outcome. Currently, there are no biomarkers for identifying which aSAH patients are at risk of developing DCI. We aimed to determine the feasibility of cerebrospinal fluid (CSF) exosomal microRNAs (miRNAs) for predicting DCI post-aSAH.

Methods: aSAH patients were prospectively enrolled, and CSF samples were collected at two time points (< 24 h and 72 h post-aSAH) from individuals undergoing external ventricular drainage. Exosomal miRNAs were isolated from the CSF for analysis. In the initial group of patients (discovery cohort), an exploratory analysis was conducted using a CSF panel containing 84 miRNAs, assessed by quantitative real-time PCR (RT-qPCR). Based on this analysis, 27 miRNAs were selected for further evaluation in a second group of patients (validation cohort). Among these, 10 miRNAs had previously been reported in SAH-related CSF studies, supporting their relevance for continued investigation.

Results: In this study, RT-qPCR analysis of 84 miRNAs in CSF samples from …

Molecular Inflammatory Expression Profiles Associated With The Frequency Of Pain In Individuals With Sickle Cell Disease, Lana Mucalo Katunaric, Shuang Jia, Ashima Singh, Mark F. Roethle, Julie A. Panepinto, David C. Brousseau, Martin J. Hessner, Amanda M. Brandow

Department of Pediatrics Faculty Papers

Pain is the most common complication of sickle cell disease (SCD). The underlying biology of SCD pain is not well understood, which is a barrier to novel, effective analgesic and preventive therapies. A wide variability in the phenotypic expression of pain exists among individuals with SCD, despite the inheritance of a similar defective hemoglobin gene. This interindividual pain variability further complicates the ability to understand the biology and effectively treat pain. We sought to discover a biological signature comprising differentially expressed genes unique to SCD that could differentiate between individuals with varied pain frequency. We conducted plasma-induced transcription analysis from …

Faculty, Staff and Students Publications

Relapse of acute myeloid leukemia (AML) and myelodysplastic syndrome (MDS) remains the primary source of mortality after allogeneic hematopoietic stem cell transplantation (HCT). Targeting programmed death-1 (PD-1) for reversing T-cell exhaustion and restoring the graft-versus-leukemia (GVL) effect may have logistical advantages over donor lymphocyte infusion. In a prospective phase 1B clinical trial, pembrolizumab was administered every 3 weeks to 16 patients with AML (n = 12) and MDS (n = 4) in relapse after HCT to assess graft-versus-host disease (GVHD), clinical response, and survival. The median time to relapse after HCT was 5.5 months and the median pretreatment bone marrow …

Institute of Emerging Health Professions Faculty Papers

A clinical trial of a multi-strain vaginal synbiotic (NCT05659745, registered 12/19/2022 at clinicaltrials.gov) led to an optimal vaginal microbiome dominated by L. crispatus (CST I). The synbiotic led to a significant increase in L. crispatus compared to placebo (p <  0.05), and conversion to CST I was significantly higher with the vaginal synbiotic than with placebo (90 vs 11%; p <  0.002). Mechanistically, the synbiotic reduced Gardnerella vaginalis and Candida, clinically important microbes.

Vaccination With Acinetobacter Baumannii Adhesin Abp2d Provides Protection Against Catheter-Associated Urinary Tract Infection, Morgan R Timm, Kevin O Tamadonfar, Taylor M Nye, Jesús Bazán Villicaña, Jerome S Pinkner, Karen W Dodson, Ali H Ellebedy, Scott J Hultgren

2020-Current year OA Pubs

Catheter-associated urinary tract infections (CAUTIs) contribute greatly to the burden of healthcare-associated infections. Acinetobacter baumannii is a Gram-negative bacterium with high levels of antibiotic resistance that is of increasing concern as a CAUTI pathogen. A. baumannii expresses fibrinogen-binding adhesins (Abp1D and Abp2D) that mediate biofilm formation on catheters, which become coated with fibrinogen upon insertion. Here we develop a protein subunit vaccine against the Abp1D and Abp2D receptor binding domains (RBD) and show that vaccination significantly reduces bacterial titers in a female mouse model of CAUTI. We further demonstrate that immunity to Abp2D

MHC class I polypeptide-related sequence B (MICB) is a ligand for NKG2D. We have shown NK cells are central to lung transplant acute lung injury (ALI) via NKG2D activation, and increased MICB in bronchoalveolar lavage predicts ALI severity. Separately, we found a MICB polymorphism (MICBG406A) is associated with decreased ALI risk. We hypothesized this polymorphism would protect against severe SARS-CoV-2 respiratory disease. We analyzed 1,036 patients hospitalized with SARS-CoV-2 infection from IMPACC. Associations between MICBG406A and outcomes were determined by linear regression or Cox proportional hazards models. We also measured immune profiles of peripheral blood and the upper and lower …
