Mansour Laboratory

The Michael K. Mansour, MD, PhD Laboratory at Massachusetts General Hospital focuses on developing novel cellular diagnostics and therapies for invasive fungal infections.

About Us

The Mansour lab investigates the critical molecular mechanisms responsible for host immune responses to life-threatening fungal pathogens. Our studies focus on neutrophils, the first line of defense against bacteria and fungi, and the role of fungal carbohydrates in innate immunity. We also perform patient-oriented research by using predictive modeling to assess risk of fungal infection in susceptible patients. Together, these investigations provide the foundation for the development of cellular therapies for infectious diseases as well as improved vaccine strategies. We hope that our research will enhance our understanding of the innate immune mechanisms against fungal pathogens that exist in our everyday environment.
