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 …

Novel Chloroviruses With Unique Glycans On Their Major Capsid Proteins, Cayden J. Homolka

Honors Program: Senior Projects (Public)

Chloroviruses, of the family Phycodnaviridae, are large, dsDNA viruses with a genome of 290 to 410 kb. These virus genomes are so large that they are classified as “giant viruses”. Within this genome, up to 16 tRNAs and 330 to 450 proteins are encoded. Among the massive amounts of genes and proteins are unique carbohydrate synthesis/metabolism genes, which are responsible for the glycosylation of chloroviruses major capsid proteins. In most viruses, these proteins are glycosylated by the host enzymes located in the endoplasmic reticulum. Instead, Chloroviruses encode their own glycosylation machinery; essentially decorating themselves. Furthermore, these chlorovirus glycans are unlike …

Faculty Research 2025

Haematopoietic stem cells maintain blood production throughout life1 . Although extensively characterized using the laboratory mouse, little is known about clonal selection and population dynamics of the haematopoietic stem cell pool during murine ageing. We isolated stem cells and progenitors from young and old mice, identifying 221,890 somatic mutations genome-wide in 1,845 single-cell-derived colonies. Mouse stem cells and progenitors accrue approximately 45 somatic mutations per year, a rate only approximately threefold greater than human progenitors despite the vastly different organismal sizes and lifespans. Phylogenetic patterns show that stem and multipotent progenitor cell pools are established during embryogenesis, after which they …

Faculty Research 2025

Although vaccines are usually given intramuscularly, the intranasal delivery route may lead to better mucosal protection and limit the spread of respiratory virus while easing administration and improving vaccine acceptance. The challenge, however, is to achieve delivery across the selective epithelial cell barrier. Here we report on a subunit vaccine platform, in which the antigen is genetically fused to albumin to facilitate FcRn-mediated transport across the mucosal barrier in the presence of adjuvant. Intranasal delivery in conventional and transgenic mouse models induces both systemic and mucosal antigen-specific antibody responses that protect against challenge with SARS-CoV-2 or influenza A. When benchmarked …

Metachronous Periprosthetic Joint Infection In Patients With Multiple Arthroplasties At Index Infection, Devin Young, Daniel Nikolaidis, Andrew Steffensmeier, Robert Runner, Mark Karadsheh

Posters

Periprosthetic joint infection (PJI) is a devastating complication of one of the most successful surgeries in medicine. About 1% to 2% of patients will develop PJI after primary total hip arthroplasty (THA) or primary total knee arthroplasty (TKA) [1]. The 5-year patient survival rate of THA PJI is estimated to be worse than that of common cancers, such as breast cancer [2]. The burden of this disease is likely to increase exponentially as the population ages and the number of patients undergoing total joint arthroplasties increases in the future [3].

Most devastating is what Murray et al deem as metachronous …
