Human noroviruses (HuNoVs) are the leading cause of acute gastroenteritis worldwide. Currently, there are no targeted antivirals for the treatment of HuNoV infection. Histo-blood group antigens (HBGAs) on the intestinal epithelium are cellular attachment factors for HuNoVs; molecules that block the binding of HuNoVs to HBGAs thus have the potential to be developed as antivirals. Human milk oligosaccharides (HMOs) are glycans in human milk with structures analogous to HBGAs. HMOs have been shown to act as decoy receptors to prevent the attachment of multiple enteric pathogens to host cells. Previous X-ray crystallography studies have demonstrated the binding of HMO 2′-fucosyllactose …

Post-surgical spinal infection occurs in up to 20 % of patients, despite aggressive peri-operative antibiotic treatments. To improve prophylaxis, we have designed and evaluated an ultrasound-activated prophylactic antibiotic release system to combat post-surgical bacterial survival. Polylactic acid (PLA) clips (1 cm3) were 3D-printed with an interior reservoir (0.8 cm3) for carrying drug payload, specifically vancomycin (VAN). Under IACUC approval, clips were surgically implanted into the spines of sheep (n = 9) and swine (n = 2) by removing the spinous process at several levels of the lumbar spine. In the sheep, clips were insonated and the …

Enteric pathogen rotavirus (RV) primarily infects mature enterocytes at the tips of the intestinal villi; however, the role of secretory Paneth and goblet cells in RV pathogenesis remains unappreciated. Atoh1 knockout mice (Atoh1cKO) were used to conditionally delete Paneth, goblet, and enteroendocrine cells in the epithelium to investigate the role of secretory cells in RV infection. Unexpectedly, the number of infected enterocytes and the amount of RV shedding in the stool were greatly decreased following secretory cell deletion. Resistance to RV infection persisted for 7 days after virus inoculation, and Atoh1 knockout mice co-housed with infected wild-type mice were uninfected, …

Bloom: Behavioral Learning And Outcome Observation In Microbes, Sean Sarwar Haque, Luke Compton Wharton, Ming Lin, Razvan Voicu

Symposium of Student Scholars

Understanding how pathogens respond to physical changes in their environment is crucial for developing effective treatments and preventative measures. Current research often relies on static models or experimental data that either fail to capture the dynamic interactions within cellular environments or are not generalizable to other types of pathogens. This project aims to address this gap by creating a comprehensive cell simulation that models pathogens and their response to chemical, physical, and physiological changes. The proposed solution is a simulation that integrates biological data and computational modeling to replicate the behavior of pathogens in real time as they are affected …

The Impact Of Diabetes On Neurovascular Integrity: A Special Focus On Pericytes And Endothelin-1, Mia Edgerton Feb 2025

The Impact Of Diabetes On Neurovascular Integrity: A Special Focus On Pericytes And Endothelin-1, Mia Edgerton

MUSC Theses and Dissertations

Diabetes increases the risk of stroke and Vascular Contributions to Cognitive Impairment and Dementia (VCID). Diabetes also dysregulates the endothelin (ET) system. ET-1-mediated constriction of brain microvascular pericytes (BMVPCs) has been shown to contribute to brain hypoperfusion. However, there is a loss of BMVPCs in VCID, but underlying mechanisms of pericyte degeneration are poorly studied. ETA receptor activation can instigate phenotypical changes and cellular senescence in endothelial cells. . There is also emerging evidence that ETB receptor agonism improves outcomes in patients with cerebral ischemic stroke, but long-term effects, especially in diabetes, are unknown. Therefore, this study aimed to determine …

School of Medicine Faculty Publications

Cutaneous lupus erythematosus (CLE) encompasses a broad range of clinical and histopathologic variants that can overlap with other dermatologic entities, complicating accurate diagnosis. We report the case of a 42-year-old male patient who initially presented with a diffuse pruritic eruption presumed to be atopic dermatitis, for which dupilumab was initiated. Within the following weeks, the patient developed a fever of unknown origin and diarrhea, raising concern for an atypical drug-related reaction or an unmasked autoimmune process. Subsequent biopsies demonstrated evolving histopathologic features, including superficial and deep perivascular dermatitis suggestive of drug eruption. In addition, a dermal mucin deposition with mixed …

Leukapheresis is a potentially life-saving therapy for children with symptomatic hyperleukocytosis. However, the standard centrifugation-based approach exposes pediatric patients to significant complications due to its large extracorporeal volume, high flow rates, and considerable platelet loss. Here, we tested whether performing cell separation with a high-throughput microfluidic technology could alleviate these limitations. In vitro, our microfluidic devices removed ~85% of large leukocytes and ~90% of spiked leukemic blasts from undiluted human whole blood, while minimizing platelet losses. Multiplexed devices connected in parallel allowed for faster, clinically relevant flow rates in vitro with no difference in leukocyte collection efficiency. When connected to …

Purpose: Current treatment guidelines strongly support the use of antiresorptive therapy in patients with newly diagnosed multiple myeloma (NDMM) with the goal of preventing skeletal related events (SRE). Despite these concrete, data-driven recommendations, the impact of delays in antiresorptive initiation in NDMM patients is understudied. Through a multicenter retrospective study, we examined the impact of delays in antiresorptive initiation on the rates of SREs. We furthered our exploration of this topic in a separate retrospective analysis with a focus on reasons for delays in antiresorptive therapy initiation. Methods: Electronic health records from two large academic institutions were used to identify …

Faculty, Staff and Students Publications

Zika virus (ZIKV) is unique among orthoflaviviruses in its vertical transmission capacity in humans, yet the underlying mechanisms remain incompletely understood. Here, we show that ZIKV induces tunneling nanotubes (TNTs) in placental trophoblasts which facilitate transfer of viral particles, proteins, mitochondria, and RNA to neighboring uninfected cells. TNT formation is driven exclusively via ZIKV non-structural protein 1 (NS1). Specifically, the N-terminal 1-50 amino acids of membrane-bound ZIKV NS1 are necessary for triggering TNT formation in host cells. Trophoblasts infected with TNT-deficient ZIKV

Takotsubo Cardiomyopathy: A Case Of The Broken Heart, Lilian Huynh, Kaylee Putney Feb 2025

Takotsubo Cardiomyopathy: A Case Of The Broken Heart, Lilian Huynh, Kaylee Putney

Annual Research Symposium

Takotsubo cardiomyopathy (TC), or "broken heart syndrome," is a rare cardiac condition causing temporary left ventricular dysfunction due to severe stress. Though the exact cause is unclear, it mimics myocardial infarction and can lead to cardiogenic shock. Current treatment lacks specific guidelines and relies on heart failure protocols. We report a case of a patient with TC-induced cardiogenic shock, likely triggered by emotional stress. She required vasopressors, a percutaneous intervention, an Impella device, and guideline-directed medication therapies. This case underscores the significance of establishing guideline optimizations for managing TC and cardiogenic shock.

BACKGROUND: Chronic alcohol consumption leads to lipid accumulation, oxidative stress, cellular damage, and inflammation in the liver, collectively referred to as alcohol-associated liver disease (ALD). FAF2/UBXD8/ETEA (Fas-associated factor 2) is a ubiquitin ligase adaptor protein that plays a crucial role in the ubiquitin-mediated degradation of misfolded proteins in the endoplasmic reticulum. A recent genome-wide association study indicated an association between FAF2 and ALD; however, the exact contribution of FAF2 to ALD pathogenesis remains unclear. METHODS: FAF2 was knocked down using AAV-delivered shRNA in C57/BL6 mice. Mice were subjected to a chronic-plus-single binge ethanol feeding (NIAAA) model. Nine hours after gavage, …

In-Silico Modeling And Characterization Of Kcc2 Protein Interaction With A Small Molecule Direct Agonist Identifies Potential Binding Sites For Modulating Behaviors Associated With Substances Of Abuse, William Hai Dang Ho, Alfred Amendolara, Kenyon Mitchell, Jaden Miner, Ruth Northcott, Braxton Bingham, Andrew J. Payne

Annual Research Symposium

Purpose

KCC2 is a potassium-chloride cotransporter that plays a critical role in neuronal function by regulating GABAergic signaling via chloride gradients. Maintaining this concentration gradient is crucial for balancing excitation and inhibition in the brain. While KCC2 dysregulation has been implicated in epilepsy and seizures, recent studies suggest that KCC2 inhibition results in phenotypes mirroring those seen in chronic opioid dependence. As such, increasing evidence support KCC2 being a potential therapeutic target for modulating behaviors associated with substances of abuse. Currently, only a few direct small molecule agonists against KCC2 have been reported, and no definitive active site on the …

BACKGROUND: Histotripsy is a novel, noninvasive, nonionizing, and nonthermal approach that uses focused ultrasound waves to treat liver tumors. This technology received a de novo Food and Drug Administration grant in late 2023. This study aimed to provide the first report on post-trial real-world clinical safety data. METHODS: Safety outcomes within 30 days of histotripsy were collected after obtaining Food and Drug Administration clearance (December 22, 2023 to July 26, 2024). All centers that performed histotripsy were invited to participate in this study. Complications requiring treatment were graded using the Clavien-Dindo classification and Comprehensive Complication Index (CCI). RESULTS: A total …

Annual Research Symposium

The bidirectional relationship between the oral and gut microbiomes has gained attention for its role in systemic and oral diseases. Dysbiosis, or microbial imbalance, disrupts these ecosystems, leading to inflammatory conditions. This research investigates the connection between these microbiomes, focusing on microbial translocation, disease correlation, and targeted interventions such as probiotics or dietary modifications to restore microbial homeostasis and reduce disease incidence.

Human growth hormone (hGH) has been in clinical use for children with GH deficiency (GHD) since the late 1950s. The original formulations were considered very safe with few adverse events reported. That changed remarkably in 1985 when the first patients with GHD, who had been treated with cadaveric hGH, were diagnosed with Creutzfeldt-Jakob disease (CJD). Fortunately, that same year a robust supply of recombinant hGH was released to the market whose adverse event profile did not include CJD. Patients who had received National Hormone and Pituitary Program hGH have been continuously followed since 1985. It is clear that prions are …
