A Noncanonical Role Of T Follicular Helper Cells In Promoting Peripheral Tolerance By Supporting T Regulatory Cells, Shivangi Dave Sep 2025

A Noncanonical Role Of T Follicular Helper Cells In Promoting Peripheral Tolerance By Supporting T Regulatory Cells, Shivangi Dave

All ETDs from UAB

T follicular helper (Tfh) cells are a specialized subset of CD4+ T cells that sup-port germinal center (GC) B cells and promote antibody (Ab)-mediated immunity. There is growing recognition of the heterogeneity and functional diversity of Tfh cells, supported by accumulating evidence that highlights their context-specific roles across a range of disease settings. While their contribution to B cell responses is well-established, our data demonstrate that Tfh cells have a broader and more dynamic function. In this study, we uncover a novel function of Tfh cells in maintaining immune homeostasis by supporting T regulatory cell (Treg) responses under normal physiological …

Air Pollution And Environmental Injustice Are Related To Respiratory Complications In Individuals With Sickle Cell Disease, Kelsey M. Maclin Sep 2025

Air Pollution And Environmental Injustice Are Related To Respiratory Complications In Individuals With Sickle Cell Disease, Kelsey M. Maclin

All ETDs from UAB

Sickle cell disease (SCD) is a genetically inherited blood disorder affecting people of African descent. SCD is characterized by painful episodes and an acute lung injury known as acute chest syndrome (ACS). Patients with SCD have a life expectancy <19 years compared to Blacks without SCD. There is minimal research investigating air pollution and health complications in SCD. The aims of this research were to investigate whether pulmonary function is affected by exposure to ambient air pollution, whether higher air pollution concentrations are associated with hospitalizations for ACS, and whether environmental injustice impacts the respiratory health of children and young adults with SCD. Air pollution data on the criteria air pollutants (CAPs) was obtained from the US Environmental Protection Agency (EPA). Patient health data were obtained from Children’s Hospital of Alabama electronic medical records. Logistic regression, distributed lag non-linear regression, Granger Causality, and Getis-Ord Gi* hot spot analysis were used to analyze our data. The EPA’s EJScreen tool was used as a measure of exposure to environmental injustice. ArcGIS was used to map the EJScreen data. Exposure to short-term air pollution is significantly associated with a reduction in pulmonary function in children and young adults with SCD. Children and young adults exposed to a one-unit increase in the monthly average concentrations of sulfur dioxide (SO2) experienced an increase in the odds of having abnormal pulmonary function. We observed the trends of each criteria air pollutant in our study to be closely aligned with the trends in the hospitalizations for ACS. Most of our study participants with a history of ACS lived in areas burdened by greater environmental injustices. Specifically, the hot spots for ACS overlapped with the hot spots for PM2.5. Unequal exposure to environmental injustices leads to increases in hospitalizations for respiratory complications in individuals with SCD. Reductions in air pollution could be greatly beneficial to the pulmonary function and overall respiratory health of individuals with SCD. Further research is needed to examine associations between air pollution and hospitalizations for ACS in individuals with SCD.

Probiotic Biogeography In The Neonatal Intestine, Sierra Hansen Sep 2025

Probiotic Biogeography In The Neonatal Intestine, Sierra Hansen

All ETDs from UAB

Neonatal infection remains a leading cause of both neonatal morbidity and mortality worldwide, particularly in preterm infants. Probiotic bacteria have been demonstrated to protect against the development of neonatal intestinal dysbiosis, however, formulations and efficacy vary substantially, highlighting a critical gap in the current understanding of the mechanisms governing probiotic efficacy in this population. This gap is exacerbated by regulatory standards which favor economic expansion over scientific rigor. Furthermore, current studies on probiotic efficacy largely rely on indirect or relative readouts of intestinal bacterial burden. Herein, we directly quantify the probiotic effects of Ligilactobacillus murinus V10 and Escherichia coli Nissle …

Targeting Streptococcus Mutans Diadenylate Cyclase For The Prevention Of Dental Caries, Edwin Miguel Rojas Jan 2025

Targeting Streptococcus Mutans Diadenylate Cyclase For The Prevention Of Dental Caries, Edwin Miguel Rojas

All ETDs from UAB

Streptococcus mutans (S. mutans) is the primary etiological agent involved in the initiation and progression of dental caries. S. mutans forms robust biofilms on the tooth surface, and current preventative treatments, such as oral rinses, eliminate both pathogenic and commensal oral species. Therefore, there is an urgent need for therapeutics which selectively inhibit S. mutans biofilms while keeping the oral microbiome intact. The diadenylate cyclase (DAC) enzyme in S. mutans plays a key role in biofilm formation. DAC converts adenosine triphosphate (ATP) into cyclic di-AMP (c-di-AMP), a secondary messenger involved in several cellular pathways. Increased levels of c-di-AMP have shown …

Chronic Inflammation Compromises Natural Killer Cell Phenotype And Function In Myeloid Leukemia, Valeriya Kuznetsova

All ETDs from UAB

Chronic myeloid leukemia (CML) and acute myeloid leukemia (AML) are blood malignancies characterized by clonal expansion and a compromised immune system. Tyrosine kinase inhibitors (TKI) revolutionized CML treatment; however, TKI discontinuation leads to relapses in half of the cases. Further, up to 10% of patients are TKI-resistant and develop a blast crisis resembling AML. Natural killer (NK) cells can clear malignant cells, representing a promising immunotherapy. However, NK cell activity is suppressed in leukemia, and the microenvironmental drivers of this impairment remain understudied. Despite this, the existing mouse models have not been tested to assess the effect of CML on …

Uncovering The Role Of Heparanase-Armed Extracellular Vesicles In Sepsis-Associated Vascular Endotheliopathy, Robert Patrick Richter

All ETDs from UAB

Sepsis remains one of the most frequent causes of mortality and life-altering morbidity in humans of all ages globally. Though sepsis pathobiology is incompletely understood, it is clear that a unifying feature of all sepsis phenotypes is systemic vascular endotheliopathy and damage to the luminal glycocalyx of endothelial cells, or eGC, that leads to organ injury. While prior work has established that heparan sulfate (HS) is an especially important eGC constituent that helps regulate a host of endothelial cell (EC) functions, its role in promoting endotheliopathy during sepsis has not been fully characterized. Additionally, previous studies in the context of …

Evaluation Of In Vitro Cardiac Models For Characterizing The Role Of Autophagy In Streptococcus Pneumoniae Infection, Georgianna Khong Jan 2025

Evaluation Of In Vitro Cardiac Models For Characterizing The Role Of Autophagy In Streptococcus Pneumoniae Infection, Georgianna Khong

All ETDs from UAB

Streptococcus pneumoniae (Spn) is a gram-positive bacterium that causes community-acquired pneumonia, the most prevalent type of pneumonia and a predominant infectious disease. There is evidence linking Spn infection to cardiovascular damage through the ability of Spn to invade and replicate in the myocardium, inducing cardiomyocyte death and disrupting cardiac function. Spn infects cardiomyocytes intracellularly through clathrin-mediated endocytosis, with demonstrated evidence of inhibitory mechanisms including clathrin-mediated endocytosis inhibitors and antioxidants. As a result, autophagy is being investigated as a potential pathway for cardiomyocyte self-defense against Spn, as it may protect cardiomyocytes intracellularly. The primary objective of this study was to evaluate …

The Role Of Altered Cell-Cell Communication Between Glia And Neurons In Alzheimer’S Disease, Tabea Marga Soelter

All ETDs from UAB

Alzheimer’s disease is the most prevalent neurodegenerative disease and is characterized by progressive memory loss and cognitive decline, affecting behavior, speech, and motor abilities. The neuropathology includes the formation of extracellular amyloid-β plaques and intracellular neurofibrillary tangles of phosphorylated tau. Additionally, neurons become functionally impaired before degenerating and dying. While neuronal loss is a disease hallmark, glia maintain neuronal health and homeostasis through cell-cell communication with neurons. Cellular crosstalk is mediated through the release of chemical intermediates (i.e., ligands), which are taken up by cell surface membrane receptors. Previous studies have shown dysregulation of global cell-cell communication patterns and communication …
