Pseudomonas Aeruginosa Exoy Enzymatic Activity Inhibits Exos-Induced Caspase-3/7 Activation But Not Cytotoxicity In Pmvecs, Connor Holm

Poster Presentations

Pseudomonas aeruginosa (P. aer.) is the most common cause of ventilator associated pneumonia (VAP) in ICU patients. Different combinations of exoenzymes (S, T, Y, and U) are found in P. aer. strains. ExoY is most often associated with VAP in ICU patients. ExoY infection of pulmonary microvascular endothelial cells (PMVECs) induces cell rounding but does not activate intracellular caspase-3/7 or cause cell death. ExoS and ExoT infection of epithelial cells leads to caspase-3/7 dependent cell death. Previous studies using epithelial cells show that ExoY alleviates the cytotoxic effects of ExoS and ExoT. Here, we sought to determine whether ExoY inhibits …

Frontier Healthscapes: Competing Narratives Of Disease, Environment, And Wellbeing In Early Minnesota, Aidan Reynolds

Geography Honors Projects

Across settler societies, health narratives were shaped by evolving tensions between lay and expert knowledge, frameworks of disease causation, and perceptions of the environment as both a source of health and a threat. In the decades following Euro-American settlement (1860-1900), Minnesota became a focal point for these debates, with its landscape fostering complex and competing narratives on health, wellbeing, and disease.

Investigating Fatty Acid Influence On West Nile Virus In Mosquitoes And Birds, Hayley Moree

Honors Program: Senior Projects (Public)

Vector-borne diseases, including Zika virus (ZIKV), Dengue virus (DENV), and West Nile virus (WNV), pose considerable global health threats, accounting for over 400 million infections and more than 700,000 deaths annually. Many vector-borne diseases are within the Flaviviridae family. Despite this, effective treatments have not been found for some flaviviruses. Flaviviruses exploit host cellular machinery to facilitate their replication and survival, reprogramming metabolic pathways, including lipid metabolism. Lipids play essential roles in the viral life cycle, providing structural components for the viral envelope, enabling membrane rearrangements for replication complexes, and supplying energy resources necessary for particle assembly.

Targeting lipid metabolism …
