Eating The Fat Of The Land: The Work Of Coxiella Burnetii To Traverse Intracellular Lipid Landscapes, Charlie Porto Apr 2025

Eating The Fat Of The Land: The Work Of Coxiella Burnetii To Traverse Intracellular Lipid Landscapes, Charlie Porto

Theses & Dissertations

Coxiella burnetii is an obligate intracellular pathogen and the causative agent of Q fever in humans. With primary hosts in livestock ruminants, C. burnetii is endemic globally, presenting significant health risks to agricultural workers and herd health at large. Numerous wild animal reservoirs exist, increasingly threatened by expanding livestock ranges. Furthermore, with a low infectious dose through aerosol transmission, the CDC considers C. burnetii a potential bioweapon, though in humans a large amount of infections persist subclinically, occasionally progressing to pneumonia and hepatitis with chronic infections leading to endocarditis.

The parasitic life cycle of C. burnetii is biphasic, a small …

Pgc-1Α Activation To Enhance Macrophage Immune Function In Mycobacterial Infections, Joel R. Frandsen, Zhihong Yuan, Brahmchetna Bedi, Zohra Prasla, Seoung-Ryoung Choi, Prabagaran Narayanasamy, Ruxana Sadikot

Journal Articles: Pathology and Microbiology

Nontuberculous Mycobacteria (NTM) are a heterogeneous group of environmental microorganisms with distinct human pathogenesis. Their incidence and prevalence are rising worldwide, due in part to elevated antimicrobial resistance which complicates treatment and potential successful outcomes. Although information exists on the clinical significance of NTMs, little is known about host immune response to infection. NTM infections alter macrophage mitochondrial capacity and decrease ATP production, efficient immune response, and bacterial clearance. Transcription factor peroxisome proliferator activated receptor (PPAR) γ coactivator-1α (PGC-1α) is a master regulator of mitochondrial biogenesis, influencing metabolism, mitochondrial pathways, and antioxidant response. Mitochondrial transcription factor A (TFAM) is a …

Central Nervous System Antiviral Pharmacology, Sean N. Avedissian Aug 2024

Central Nervous System Antiviral Pharmacology, Sean N. Avedissian

Theses & Dissertations

Soon after viral infection, viruses like Human Immunodeficiency Virus (HIV) and SARS-CoV-2 can disseminate throughout the body and establish reservoirs in the central nervous system (CNS). The persistence of viruses in cells of these reservoirs is a major obstacle to virus eradication. This is due to the abundance of cells/receptors that these viruses utilize to gain entry into cells found at these various reservoir sites. Consequently, these same anatomical sites also may be pharmacologic sanctuaries, as evidenced by concentrations of antiretroviral drugs (ARVs) and antivirals (AVs) that are lower in reservoirs than those in peripheral blood; in some cases, these …


Dying Right: Supporting Anti-Cancer Therapy Through Immunogenic Cell Death, Elizabeth Schmitz Aug 2024

Dying Right: Supporting Anti-Cancer Therapy Through Immunogenic Cell Death, Elizabeth Schmitz

Theses & Dissertations

The primary goal of most anti-cancer therapy is to eradicate neoplastic cells. Simultaneously, neoplastic cell death is the first step of the cancer-immunity cycle, which starts with the release of antigens from cancer cells and ends with T-cell directed killing of cancer cells, in addition to long-standing memory to tumor antigens encountered. Immunogenic damage-associated-molecular patterns (DAMPs) are endogenous cell molecules repurposed in times of insurmountable cell stress (e.g., CALR, ATP, HMGB1) to facilitate communication between dying cells and adaptive immune cells, acting as adjuvants for the cancer-immunity cycle, in a cellular fate termed immunogenic cell death (ICD). It …
