The interferon-inducible transmembrane protein (IFITM) family inhibits a growing number of pathogenic viruses, among them influenza A virus, dengue virus, hepatitis C virus, and Ebola virus. This review covers recent developments in our understanding of the IFITM's molecular determinants, potential mechanisms of action, and impact on pathogenesis. IFITMs are host intramembrane proteins that block viral fusion resulting in virus degradation. IFITMs inhibit a growing number of pathogenic viruses, including influenza A virus, dengue virus, and Ebola virus. Mice null for Ifitm3 exhibit increased disease severity when infected with the influenza A virus. Patients expressing a variant allele of IFITM3 are more likely to develop severe influenza infection. Recent work suggests that IFITMs may toughen the host membrane, thus preventing viral membrane fusion.
