Early Immune Dysregulation In Mtb/Siv Co-Infection Resists Cart Treatment At The Single-Cell Level, Riti Sharan, Yi Zou, Zhao Lai, Korri Weldon, Todd Bradley, Xi Luo, Hulin Wu, Shabaana A Khader, Deepak Kaushal

Faculty, Staff and Student Publications

Using single-cell transcriptomics of bronchoalveolar lavage cells from Mtb/SIV co-infected rhesus macaques on cART, we reveal profound immune dysregulation during early SIV co-infection of latent tuberculosis. SIV induces a sharp decline in CD4+ T cells, NK, and NKT cells, with incomplete recovery of Mtb-specific TH1 effector responses despite viral suppression. Instead, a persistent TH17-skewed environment emerges, alongside sustained myeloid inflammation driven by Type I interferon signaling and pro-inflammatory regulators such as KLF6 and NFKB1. Ligand-receptor network analyses demonstrate expanded CD4+ T cell-macrophage crosstalk and loss of immune homeostasis that cART fails to fully restore. These findings expose …

Quantifying Black Carbon Concentrations in Georgia and Analyzing Associated Public Health Risks

One of the most daunting challenges of the industrial world is air pollution. Within this broad spectrum, there is an inhalable particle group named PM2.5, which contains black carbon. Black carbon has evidence that supports the generation and worsening of adverse health impacts, which may include birth complications, cognitive deficits in children, pulmonary aggravation, asthma, cardiovascular issues, neurological degenerative patterns, and cancer risk. This is especially seen in vulnerable populations, like children, elderly, and those who already suffer from weakened health, many of which reside in the southern …

Bio 340 Final Project: Rural Population Structure And Food Production Interact To Shape Global Undernourishment, Ava Ripanti

Biology Student Scholarship

Ava Ripanti - Environmental Biology '27

Undernourishment remains a major global public health challenge, reflecting the proportion of a population lacking sufficient dietary energy intake. While food availability is central to food security, undernourishment is also shaped by structural and socioeconomic factors such as population distribution and access to resources. Although rural populations are closely tied to agriculture, they often experience higher food insecurity due to limited infrastructure, market access, and healthcare. Prior research emphasizes that broader determinants, particularly inequality and development, are stronger predictors of undernourishment than agricultural output alone, that food insecurity exists in both rural and urban …

Validation Of A Real-Time Pcr Laboratory Developed Test For The Detection Of Pneumocystis Jirovecii In Bronchoalveolar Lavage Samples, Caitlyn Moon

Honors Scholar Theses

Pneumocystis jirovecii is an opportunistic, host-obligate fungal pathogen responsible for causing P. jirovecii pneumonia (PJP) in humans. PJP is treated with trimethoprim-sulfamethoxazole (TMP-SMX), a strong broad-spectrum antibiotic that carries risk of renal and hepatotoxicity. Therefore, rapid diagnosis or exclusion of PJP is crucial to ensure PJP-positive patients receive effective treatment and PJP-negative patients avoid unnecessary antibiotics. Unlike most microorganisms, P. jirovecii cannot be cultured, presenting complications for the typical methods of diagnosing fungal pathogens. Historically, the gold standard for diagnosis was direct microscopic examination with stains such as methenamine silver and calcofluor white, but this diagnostic technique requires highly skilled …

We used NHANES 2011-2014 data to fit a survey-weighted logistic regression model predicting psoriasis diagnosis based on sex, age group, race/ethnicity, education, and poverty level. These demographic coefficients were applied to U.S. Census-derived county populations …

Food Insecurity As A Primary Driver Of Cardiometabolic Disease Across Georgia Census Tracts, Jordan R. Howard, Thomas Last, Winston Price

Research Day

Introduction: Cardiometabolic diseases including diabetes, hypertension, and obesity remain leading causes of morbidity and mortality in the United States and disproportionately affect communities across the southeastern region. In Georgia, disease burden is concentrated in rural counties and economically disadvantaged urban areas. Public health frameworks have traditionally attributed these disparities to limited physical access to healthy food, commonly described as “food deserts,” where distance to grocery stores is presumed to constrain dietary quality and worsen metabolic health. However, growing evidence suggests that economic food insecurity may play a larger role in cardiometabolic risk than geographic food access. Few studies have evaluated …
