Our laboratory focuses on entry processes of enveloped viruses and the various ways that the innate and adaptive immune responses inhibit these processes. We also apply our insights toward developing therapeutic strategies that enhance or supplement these immune responses. Our work can be divided into three categories: (1) biochemical studies of the HIV-1 entry process and its inhibition, (2) identification and characterization of obligate factors, including receptors, necessary for the entry of other enveloped viruses, and (3) identification and characterization of host restriction factors that inhibit early steps in the viral life cycle, in particular those of the IFITM family.
