The COVID-19 pandemic highlights the necessity of emergency response and pandemic preparedness, especially for emerging viral threats. Currently, virus-specific vaccines and antivirals are the primary tools to combat viral diseases; however, broad-spectrum antivirals that target more than one virus species could provide additional protection from emerging and re-emerging viral diseases (Andersen et al. 2020; Zhu et al. 2015; Hickman et al. 2022).
Clustered regulatory interspaced short palindromic repeat (CRISPR)-associated endonucleases have become recently utilized as potential antiviral strategies due to their high specificity, efficacy, and versatility (Najafi et al. 2022). While CRISPR-based antivirals have previously been used to target specific …
Role And Regulation Of Staphylococcal Cell Death, Abdulelah Ahmed Alqarzaee S
Role And Regulation Of Staphylococcal Cell Death, Abdulelah Ahmed Alqarzaee S
Theses & Dissertations
The transition from growth to stationary phase is a natural response of bacteria to starvation and stress. When stress is alleviated and more favorable growth conditions return, bacteria resume proliferation without a significant loss in fitness. Although specific adaptations that enhance persistence and survival of bacteria in stationary phase have been identified, mechanisms that help maintain the competitive fitness potential of non-dividing bacterial populations have remained obscure. This dissertation demonstrates that staphylococci entering stationary phase following growth in excess glucose undergo regulated cell death to maintain the competitive fitness potential of the population. Upon a decrease in extracellular pH, the …
Insights Into The Chlamydial Niche: The Dynamic Roles Of Inclusion Membrane (Inc) Proteins In Chlamydia Trachomatis Development, Macy G. Wood
Theses & Dissertations
Chlamydia trachomatis (Ctr) is the leading cause of bacterial sexually transmitted infections. Ctr, an obligate intracellular bacterium, develops within a membrane-bound vacuole called an inclusion. The inclusion membrane is modified by chlamydial inclusion membrane (Inc) proteins, the functions of which are poorly characterized. Bacterial two-hybrid analyses found some Incs (e.g., IncF) interacted with numerous Incs while others (e.g., IncA) did not. We hypothesize that some Incs organize the inclusion through Inc-Inc interactions whereas other Incs promote chlamydial-host interactions by binding eukaryotic proteins. To test our hypothesis, we implemented the ascorbate peroxidase proximity labeling system (APEX2), which labels proximal proteins with …
