In response to MCMV infection, NK cells undergo three distinct phases of proliferation: the non-specific phase mediated by pro-proliferative cytokines; the specific phase mediated by recognition of an MCMV-encoded protein by an NK cell activating receptor, Ly49H; and the resolution phase, whose mechanism is unknown. MCMV infection of RAG mice, which lack all adaptive immune cells, results in prolonged proliferation of NK cells despite similar viral titers compared to wildtype mice. Interestingly, there are different kinetics for Ly49H+ and Ly49H- NK cells. We have identified several additional markers that may distinguish NK cells that have been specifically activated through their …
