(MIP-1
)–dependent Pathways
Natural killer (NK) cells mediate defense against early murine cytomegalovirus (MCMV) infections in liver. The chemokine, macrophage inflammatory protein 1
(MIP-1
), can promote inflammatory responses. Our studies evaluated contributions of NK cells to early MCMV-induced liver inflammation and MIP-1
requirements for inflammation and delivery of antiviral defenses. NK cells were shown to be responsible for focal inflammation, and to be induced to migrate at high levels, in MCMV-infected livers. MIP-1
gene expression was elevated at coinciding times, and mice deficient in MIP-1
function were dramatically inhibited in both inflammatory and protective liver responses. The results precisely define MIP-1
–dependent steps required to achieve NK cell inflammation during, and mechanisms promoting defense against, viral infections in tissues.
