Monica Alvarez is looking at the functional intersect of human genetic variation and susceptibility to Typhoid fever. Specifically, she studies how human genetic variation that decreases expression of VAC14, a host phosphoinositide scaffolding protein, modulates membrane lipids and subsequently increases Salmonella Typhi invasion. This association is not only seen in tissue culture but was also confirmed in a Typhoid Susceptibility study in Vietnam. Additionally, Monica has created a Zebrafish model to study early Salmonella infection. This model has shown that pretreating the Zebrafish with lipid-modifying drugs has a protective effect against Salmonella Typhi infection. This project has added to our understanding of basic host-pathogen interactions and may also have implications for prophylactic therapeutics against Typhoid Fever.
