In contrast to general findings that mouse and human cytotoxic T lymphocytes (CTL) are restricted in cytotoxic activity by major histocompatibility complex (MHC) class I antigens, we previously found that some herpes simplex virus (HSV) type I-infected cells that shared no HLA class I antigens with the HSV-1-stimulated lymphocytes were lysed. In this study, we addressed the question of the role of HLA antigens in human T cell-mediated lysis of HSV-1-infected cells by generating clones of HSV-1-directed CTL from two HSV-1-seropositive individuals. CTL clones that lysed autologous HSV-1-infected lymphoblastoid cell lines (LCL), but not natural killer-sensitive K562 cells or uninfected or influenza virus-infected LCL, were tested for cytotoxicity against a panel of allogeneic HSV-1-infected LCL. Clone KL-35 from individual KL lysed only HSV-1-infected LCL sharing the HLA class II MB1 antigen with KL. With all four CTL clones isolated from individual PM, only HSV-1-infected LCL sharing DR1 with PM were lysed. Monoclonal antibody s3/4 (directed against MB1 ), but not TS1/16 or B33 .1 (directed against a DR framework determinant), blocked lysis of autologous HSV-1-infected cells by KL-35. In contrast, B33 .1, but not s3/4, blocked lysis of autologous HSV-1-infected cells by the PM CTL clones but not by KL-35. Together, these results indicate that our five human CTL clones which are directed against HSV-1-infected cells, and which are all OKT3+, OKT4+, OKT8-, are restricted in lytic activity by HLA class II MB and DR antigens. These results suggest that the HLA D region-encoded class II antigens may be important in the recognition and destruction of virus-infected cells by human CTL.
