    Natural killer (NK) cells can kill virus-infected cells without prior antigenic exposure, and are therefore important for controlling viral replication prior to the onset of adaptive immune responses. Primate NK cells express activating and inhibitory killer-cell immunoglobulin-like receptors (KIRs) that bind to specific major histocompatibility complex (MHC) class I molecules. The importance of KIR interactions with MHC class I in human immunodeficiency virus (HIV) pathogenesis is demonstrated by the association of select KIR and MHC class I genotypes with delayed progression to acquired immunodeficiency syndrome (AIDS).
