Interferon protects primary macrophages against HIV infection

Interferon (IFN) is a unique type I IFN that is not induced by pattern-recognition response elements. IFN is constitutively expressed in mucosal tissues including the female genital mucosa. We show here that IFN induces an antiviral state in human macrophages that blocks HIV-1 replication.
