SSA - Elucidating the role of Endocytosis in Candida survival and proliferation in host cells

Lead Research Organisation: University of Sheffield
Department Name: Biomedical Science

Abstract

Fungi such as Candida species are a major cause of hospital-acquired infections especially in elderly and immuno-compromised patients, and invasive candidiasis is associated with a high mortality rate. Central to Candida albicans virulence is the ability of cells to switch shape between round yeast and filamentous hyphal forms. This capacity is thought to allow the organism to disseminate effectively in blood (as yeast) and through tissues (with hyphae). There is increasing evidence implicating the endocytic pathway in the mechanism for bud to hyphal transition, and in the maintenance of polarised growth in hyphae. This project will allow unprecedented insight into machinery underlying C.albicans environmental fitness and interaction with host cells. Specifically, the student will-
1. investigate the importance of the C.albicans endocytic pathway for survival and proliferation following uptake by macrophages
2. develop tools to investigate surface levels of key proteins following macrophage uptake
3. use a zebrafish model system to determine whether endocytically-compromised Candida can proliferate and be disseminated in vivo
Overall, the successful student will benefit from a multi-disciplinary project to be undertaken within internationally-recognized laboratories. They will gain expertise in in vitro and in vivo cell techniques as well as in a range of advanced microscopy approaches.
