The research of Lena Heung, MD, PhD, focuses on the roles of innate immune cells in the host response to respiratory fungal pathogens, in particular Cryptococcus neoformans. C. neoformans is an environmental fungus that can cause highly fatal lung and central nervous system infections in immunocompromised patients, including those with HIV/AIDS, cancer, solid organ transplantation and autoimmune conditions. The goal of Dr. Heung's research is to define the innate immune mechanisms that determine host outcomes after infection in order to facilitate the development of immunomodulatory therapies for susceptible patients. The Heung Lab has established detrimental roles for inflammatory monocytes and signaling through the DAP12 adapter molecule during cryptococcosis. Currently, the lab is investigating the cellular and molecular mechanisms by which inflammatory monocytes regulate the host response to C. neoformans and further dissecting the DAP12 signaling cascade and its role in integrating fungal sensing and downstream effector functions.
