The ability of highly lytic herpes simplex virus (HSV) cytolytic T lymphocytes to modulate the interaction between the murine host (adult C57BL/6 [H-2b] mice) and HSV type 1 Patton resulting in acute infection in the footpad and latent infection in the sensory lumbosacral dorsal root ganglia (L6, L5, L4, and L3) innervating the footpad was investigated. Results indicated that a critical threshold level of infectious HSV was required to establish infection. The adoptive transfer of cytolytic T lymphocytes derived from in vitro cultures after restimulation with HSV-infected, syngeneic stimulator cells exhibiting class I H-2-restricted, L3T4- Lyt-2+ HSV-specific cytolytic activity immediately before infection with a high dose of HSV reduced the levels of infectious HSV recovered from the footpad tissue during acute infection and the levels of latent HSV reactivated from the dorsal root ganglia to levels expected from mice infected with a low dose. Depletion of Lyt-2+ cells from the transferred population abrogated the protective ability, while depletion of L3T4+ cells had little effect. These results suggest that functionally lytic HSV-specific cytolytic T lymphocytes present at the time of HSV infection have the potential to participate in the control of the acute infection and in the subsequent establishment of latent infection.
