Dynamics of Ly49 expressing cytotoxic lymphocyte subsets in response to virus infection

Microbes Infect. 2002 Dec;4(15):1481-90. doi: 10.1016/s1286-4579(02)00031-x.

Abstract

Viral infections induce first a loss and then an increase in natural killer (NK) and CD8(+) T cells. NK cells expressing Ly49G2 were selectively expanded by several viruses and poly I:C. CD8(+) T cells expressing Ly49G2 were selectively expanded by poly I:C and participated in the antigen-specific response to lymphocytic choriomeningitis virus.
