title: Role of T-lymphocyte subsets in recovery from herpes simplex virus infection.
abstract: Our investigations probed the nature of different T-lymphocyte subsets effecting clearance of herpes simplex virus after infection of the pinna. Cell populations from animals recently infected subcutaneously or intraperitoneally (acute population) or from animals infected 6 weeks previously (primed population) or the latter cells reimmunized in vitro with virus (memory population) were studied. Viral clearance was a function of the Lyt 1+2- subset in the acute population, but with the memory population both Lyt 1+ and Lyt 2+ cells affected clearance. In primed populations, viral clearance was effected only by the Lyt 2+ subset. The ability of the various cell populations to adoptively transfer delayed-type hypersensitivity was also studied. Only acute population cells from animals infected subcutaneously and memory population cells transferred delayed-type hypersensitivity. In both cases, the cell subtype was Lyt 1+2-. Our results demonstrated that the delayed-type hypersensitivity response does not always correlate with immunity to herpes simplex virus. Multiple subsets of T cells participate in viral clearance, and their respective importances vary according to the stage of the virus-host interaction.
