Research Summary:

Our research objective is to contribute to a comprehensive understanding of the innate immune control of viral infections, and help create novel therapies for viral diseases based on this understanding. Recently, we identified a family of interferon-inducible transmembrane (IFITM) proteins critical to the intrinsic and innate immune control of several highly pathogenic viruses, including SARS coronavirus, influenza A viruses, dengue virus, West Nile virus, Ebola virus, and Marburg viruses. The IFITM protein family has four human paralogs, IFITM1, 2, 3, and 5. As their names indicate, expression of IFITM proteins is strongly induced by both type I and type II interferons. Our studies demonstrated that IFITM proteins restrict viral replication at the early stage of their lifecycles. We also showed that IFITM proteins differentially restrict influenza A viruses and filoviruses. In vivo, IFITM-mediated restriction plays a pivotal role in control of influenza A virus replication. We observed that Ifitm knockout mice developed more severe clinical presentations than wild type mice after challenged with influenza A viruses.  

Based on previous IFITM work, our current research focuses on (1) understanding the mechanisms of IFITM-mediated viral restriction, (2) investigating the role of IFITM proteins in modulation of adaptive immunity, (3) determining the importance of human IFITM polymorphisms in control of viral infections, and (4) identifying compounds which upregulate the expression of IFITM proteins. Several approaches are used in our lab, including flow cytometry, confocal microscopy, immunoprecipitation, siRNA and drug screens, and animal experiments. These studies may (1) deepen our knowledge of how innate immunity controls viral infection and modulates adaptive immunity, (2) identify populations which are sensitive to specific viral infections, (3) help define and limit the use of antivirals, and (4) provide new approaches for the treatment of viral diseases..
