ScRNA-Seq of negatively enriched NK cells 4 days post MCMV infection

ABSTRACT: Ly49G2+ NK cells mediate essential control of murine cytomegalovirus (MCMV) infection in mice which express the H-2Dk class I molecule. As a cognate ligand for specific Ly49G2 inhibitory receptor allotypes, H-2Dk also licenses Ly49G2+ NK cells in naïve and MCMV-infected mice. These findings suggest Ly49G2 may promote antiviral NK cell activities during MCMV infection. Indeed, in mice lacking the Ly49G2 receptor, MCMV resistance is fully abrogated. Additionally, NK cells expressing Ly49R, an NK cell associated activation receptor that also recognizes H-2Dk, have their function augmented by Ly49G2 and are required for MCMV resistance.
