Structural Basis Of Panx1 Permeation And Positive Modulation By Mefloquine, Yangyang Li, Zheng Ruan, Junuk Lee, Ian Orozco, Edward Zhou, Juan Du, Wei Lü

Department of Biochemistry and Molecular Biology Faculty Papers

Purinergic signaling relies on ATP release through exocytosis and large-pore channels. Large-pore channels permeate both small anions like chloride and large signaling molecules like ATP, but how this broad cargo selectivity is structurally controlled remains elusive. Here we investigate PANX1, a prototypical large-pore channel, and uncover structural plasticity at the extracellular entrance formed by seven tryptophan (W74) residues. The W74 sidechains are flexible, sampling conformations that range from a constricted state permissive only to chloride to a dilated state compatible with ATP. These states are coupled to variable cation-π interactions between W74 and arginine 75 (R75), suggesting a mechanism for …


Role Of Cellular Stress Responses In Innate Immune Defense Against Acute Respiratory Infections, Amit Sharma Dec 2025

Role Of Cellular Stress Responses In Innate Immune Defense Against Acute Respiratory Infections, Amit Sharma

LSU Doctoral Dissertations

The endoplasmic reticulum (ER) stress sensor inositol-requiring enzyme 1α (IRE1α) is an important regulator of innate immune cells. However, its role in pulmonary innate host defenses remains poorly understood. This dissertation elucidates the dual, context-dependent role of IRE1α in host defense against methicillin-resistant Staphylococcus aureus (MRSA) pneumonia. We demonstrate IRE1α’s function as both a detrimental mediator of acute pathology and an essential facilitator of innate immune memory. Our work revealed that acute IRE1α activation during primary MRSA infection is detrimental. In lungs and alveolar macrophages (AMs), IRE1α is activated in response to MRSA infection. Consequently, IRE1α activation triggers a hyperinflammatory …

Variable expressivity of disease-associated variants implies a role for secondary variants that modify clinical features. We assessed the effects of modifier variants on the clinical outcomes of 2,455 individuals with primary variants. Among 124 families with the 16p12.1 deletion, distinct rare and common variant classes conferred risks for specific developmental features, including short tandem repeats for neurological defects. Network analysis suggested distinct mechanisms involving 16p12.1 genes and secondary variants specific to each proband. Within disease and population cohorts of 976 individuals with the 16p12.1 deletion, we found opposing effects of secondary variants on clinical features across ascertainments. Additional analysis of …

Kinesiology and Health Science Student Research

Falls are a leading cause of injury and loss of independence in older adults, often linked to deficits in lower-limb muscle function and gait mechanics. Eccentric exercise can improve muscular resilience, while aquatic walking offers a safe, supportive environment to retrain gait; however, little is known about how these modalities interact at the neuromuscular level. This study compared lower-limb muscle activation during gait on land and in water, before and after an acute bout of eccentric exercise, in healthy young adults. Surface electromyography was collected from the tibialis anterior (TA), gastrocnemius medialis (GM), vastus lateralis (VL), and biceps femoris (BF) …

Predicting, Culturing, And Characterizing Beneficial And Detrimental Strains Associated With Plant Phenotypes., Anastasiia Onyshchenko

Arts & Sciences Graduate Student Theses and Dissertations

Modern agriculture’s reliance on chemical fertilizers has greatly increased crop yields but has also contributed to soil degradation, environmental pollution, and unsustainable resource use. Plant growth–promoting rhizobacteria offer a sustainable alternative, enhancing plant growth through mechanisms such as nitrogen fixation, phosphate solubilization, siderophore production, and phytohormone modulation, while also protecting plants against pathogens and abiotic stresses. However, soil microbial communities are highly diverse and structurally complex, making the isolation of individual beneficial strains challenging. Traditional approaches rely on selective media and labor-intensive phenotypic screening, which often capture only a small fraction of soil diversity. To overcome these limitations, we combined …


Microplastic Exposure Alters Tubulin Leading To Alterations In Insulin Secretion By Pancreatic Beta Cells, Anakaren Garcia Dec 2025

Microplastic Exposure Alters Tubulin Leading To Alterations In Insulin Secretion By Pancreatic Beta Cells, Anakaren Garcia

Honors Program Theses and Research Projects

Abstract

Diabetes mellitus is a metabolic disorder characterized by elevated blood glucose levels due to impaired insulin secretion or diminished cellular response to insulin (resistance). Pancreatic β-cells depend on a well-organized cytoskeleton, particularly microtubules composed of α- and β-tubulin heterodimers, to transport insulin granules to the plasma membrane during glucose-stimulated insulin secretion (GSIS). Disruption of microtubule organization can impair granule trafficking and reduce insulin release. However, emerging environmental toxicants such as microplastics that interfere with β-cell cytoskeletal function remains largely unexplored.

Microplastics (MPs) are small plastic particles (< 5 mm) that have become widespread environmental contaminants and can enter biological systems. Previous studies have shown that MPs can induce cellular stress and protein misfolding, but their effects on microtubules in pancreatic β-cells are not well characterized. This study investigates whether exposure to fluorescent polystyrene microplastics alters microtubule organization and insulin secretion in βTC-6 cells.

βTC-6 cells were treated with 10 µg/mL of fluorescent polystyrene microplastics for …


High School Science Experience For Students With Cognitive Disabilities: A Pilot Study, Cassandra Wychers Dec 2025

High School Science Experience For Students With Cognitive Disabilities: A Pilot Study, Cassandra Wychers

Honors Theses

Although education has become more adaptive, inclusive of all students who learn differently including for people with cognitive disabilities, closer examination may reveal that high school science classrooms are still challenging learning spaces. Science is an important part of the school curriculum as it teaches students about engaging in the world around them while also encouraging skills involving evidence, inquiries, and critical thinking. All students are entitled to learn science in their classrooms even if they have a cognitive disability (Apanasionok, et al. 2019). Although there are many complexities to defining disability in the world and in education, this study …


White Nose Syndrome In Bats And Infant Mortality In Georgia, Rhys Medcalfe, Sean Medcalfe, Simon Medcalfe Dec 2025

White Nose Syndrome In Bats And Infant Mortality In Georgia, Rhys Medcalfe, Sean Medcalfe, Simon Medcalfe

Journal of the Georgia Public Health Association

Background: White nose syndrome (WNS) is a disease in bats caused by the fungus Pseudogymnoascus destructans that can result in bat mortality rates of over 90%. WNS was discovered in Georgia in 2012 in 3 counties but has continued to spread to 14 counties as of 2023, with P. destructans detected in a further seven. Biodiversity loss has been linked to human health outcomes including infant mortality. Understanding the link between WNS, biodiversity loss, and infant mortality in Georgia is important because Georgia ranks 42nd out of the 50 states for infant mortality rate.

Methods: Using panel data from …

Parkinson's disease (PD), Dementia with Lewy bodies (DLB), and multiple system atrophy (MSA), are characterized by the misfolding and aggregation of alpha-synuclein (αSyn). Compelling evidence showed that αSyn aggregates exist as distinct conformational strains in different synucleinopathies. Recently, we reported that the αSyn Seed Amplification Assay (αSyn-SAA) can amplify and distinguish αSyn strains from PD and MSA. In this study, we investigate whether MSA-seeded, SAA-amplified αSyn fibrils retain the biological and structural properties of the αSyn seeds present in MSA brains. We study the biological activities of both brain-derived and SAA-amplified αSyn aggregates using an αSyn "biosensor" cell model and …

Ifnγ-Driven Skewing Towards Th1 Over Th17 Differentiation Underlies Crs And Neutropenia In Car-T Therapy, Payal Goala

USF Tampa Graduate Theses and Dissertations

CAR-T therapy has improved overall and complete response rates, andprolonged progression free survival of patients with relapsed/refractory hematological malignancies. The short-term and long-term impacts of anti-CD19 CAR-T products on the immune landscape of B cell malignancies has garnered considerable attention in recent years. Most notably, a subset of patients experience high-grade cytokine toxicities, including cytokine release syndrome and immune cell-associated hematologic toxicity that manifest as prolonged cytopenia. Whereas etiology of CRS is more well established, the mechanisms leading to CAR-T associated cytopenia remains elusive. Rejeski et. al. showed that severe cytopenia in patients post CAR-T treatment led to frequent infections …

Kimmel Cancer Center Faculty Papers

Cold atmospheric pressure plasma (CAP) is emerging as a clinically relevant therapy for dermatological conditions such as actinic keratosis, warts, and chronic wounds. However, these therapies lack strategies to monitor CAP delivery in situ and to ensure delivery of an effective CAP dose without unwanted toxicity. CAP acts as a therapeutic agent in these biomedical applications primarily (but not solely) through reactive oxygen and nitrogen species (RONS) generated at transiently high local concentrations. Here we demonstrate the use of bio-electrochemical sensors capable of real-time measurements of key CAP RONS: hydrogen peroxide and oxidation-reduction-potential (ORP). In in vitro scratch assays and …


The Effectiveness Of Telemedicine As A Pivotal Tool In Providing Accessible Medical Care, Peyton Wilt Dec 2025

Critical evaluation and refinement of animal models is essential for neuroscientists to understand complex physiological and pathological processes related to psychiatric diseases. In general, preclinical studies modeling drug dependence and problematic substance use have been limited to the administration of a single substance; however, there is a growing appreciation that this approach has failed to capture the complexities of humans and has stifled translational efforts. Polysubstance use represents the overwhelmingly common patterns of alcohol and drug use in humans. For example, epidemiological studies generally determine that between 70–95 % of individuals with alcohol use disorder use tobacco daily, and upwards …

Early-stage breast cancers resistant to neoadjuvant therapy (NAT), characterized by high residual cancer burden (RCB) after treatment, have an increased risk of metastatic recurrence. Here, we show that circulating tumor DNA (ctDNA) detected using a tumor-informed test (1) can improve risk stratification of patients with NAT-resistant tumors (RCB-II/RCB-III) and (2) predict response to NAT. Stratification using ctDNA status at pretreatment or post-NAT and ctDNA dynamics identified NAT-resistant tumors with a significantly decreased risk of metastatic recurrence. ctDNA clearance as early as week 3 across receptor subtypes predicted favorable responses to NAT, including immunotherapies. Interestingly, less than a fifth of patients …

The human brain contains a milieu of extracellular matrix (ECM) components that promote normal development and physiology. ECM signaling pathways are often dysregulated in brain pathologies including the malignant cancer glioblastoma (GBM). Here, we used single-cell spatial transcriptomic platforms to map the expression of nearly 400 ECM genes in matching non-cancerous brain and GBM samples. At least four different GBM cell populations have been identified that show unique ECM expression profiles and spatial enrichment in distinct intratumor regions. Spatial mapping demonstrates largely non-overlapping expression signatures of ECM components in GBM stromal cell types, particularly in vascular endothelial cells and microglia/macrophages. …

Mitochondrial Insoluble Aggregates In Aging And Alzheimer’S Disease Models: Cross-Species Proteomic Integration, Identification Of Conserved Candidates, And Pharmacological Disruption Of Eef-2 Interactions, Sonu Pahal

Theses and Dissertations

Protein aggregation within mitochondria emerges early in both aging and Alzheimer’s disease (AD) and contributes to progressive loss of proteostasis. Insoluble mitochondrial aggregate fractions from Caenorhabditis elegans revealed extensive enrichment of metabolic and translational proteins that also appear in human Alzheimer hippocampal aggregates. Comparative analysis across age and genotype identified a conserved subset of aggregation-prone proteins, several of which cluster around elongation factor 2 (eEF-2), a regulator of ribosomal translocation and energy coupling. Cross-species integration defined a network in which eEF-2 links chaperones, metabolic enzymes, and RNA-binding proteins that co-aggregate in both human Alzheimer material and nematode models. Functional tests …
