Research Abstract
Candida albicans is one of the most frequently isolated fungal pathogens in humans, causing mucosal infections of the oral cavity and reproductive tract in otherwise healthy people, and also causing life-threatening systemic infections in immunocompromised individuals. C. albicans is polymorphic and undergoes reversible morphogenetic transitions between budding yeast, and pseudohyphal and hyphal growth forms. Its ability to switch growth forms is important for the virulence of C. albicans. A major emphasis of our research has been to understand how C. albicans senses host signals and regulates its growth forms and ability to survive and infect at different host sites. Our recent studies focus on identifying yeast and hyphal specific cell surface proteins that modulate the host immune response. Another area of our research is antifungal drug discovery and mechanisms of drug resistance.
