Interferon ε protects primary macrophages against HIV infection


ABSTRACT: Interferon ε (IFNε) is a unique type I IFN that is not induced by pattern-recognition response elements. IFNε is constitutively expressed in mucosal tissues including the female genital mucosa. We show here that IFNε induces an antiviral state in human macrophages that blocks HIV-1 replication. In this work, we examined effects and underlying mechanisms of IFNε in HIV infection of monocyte-derived macrophages (MDMs). We found that IFNε blocked HIV replication in macrophages. It acted on early stages of the HIV life cycle including entry and reverse transcription. It did not appear to operate through known IFN-induced HIV host restriction factors. IFNε induced immune responses in primary macrophages distinct from those induced by IFNα. Importantly, we discovered a novel protective effect of IFNε in primary macrophages against HIV by surging reactive oxygen species (ROS).
