RESUMO
A function(s) involved in the altered susceptibility of herpes simplex virus type 2 (HSV-2)-infected cells to specific lysis by cytotoxic T lymphocytes was mapped in the S component of HSV-2 DNA by using HSV-1 X HSV-2 intertypic recombinants (RH1G44, RS1G25, R50BG10, A7D, and C4D) and HSV-1 MP. Target cells infected with R50BG10, A7D, and C4D exhibited reduced levels of cytolysis, as did HSV-2-infected cells, whereas RH1G44 and RS1G25 recombinant-infected and HSV-1 MP-infected cells showed levels of lysis equal to that of HSV-1 KOS-infected cells. The intertypic recombinants R50BG10, RS1G25, RH1G44, and HSV-1 MP induced cross-reactive cytotoxic T lymphocytes. Coinfection of cells with HSV-1 KOS and either HSV-2 186 or R50BG10 recombinant also resulted in a decrease in the level of specific lysis by anti-HSV cytotoxic T lymphocytes.
