Importance of interferon inducible trans-membrane proteins and retinoic acid inducible gene I for influenza virus replication: A review

Abstract

Understanding the interplay between Influenza viruses and host cells is key to elucidating the pathogenesis of these viruses. Several host factors have been identified that exert antiviral functions; however, influenza viruses continue to replicate utilizing host cell machinery. Herein, we review the mechanisms of action of two host-derived proteins on conferring cellular resistance to the influenza virus; (1) the interferon inducible trans-membrane proteins, 1, 2 and 3, a recently identified family of early restriction factors; and (2) retinoic acid inducible gene I, a key mediator of antiviral immunity. These data may contribute to the design of novel and efficient anti-influenza treatments.
