The appearance of specific cytolytic T lymphocytes (CTL) is a prominent feature of cell-mediated immune responses to viral infections and to aliografts. CTL kill their target cells through a process consisting of at least three steps:(1) antigen recognition and celhceil adherence,(2) a Ca^-dependent lethal hit, and (3) target cell death. The highly specific nature of the antigenic recognition observed in T cell-mediated cytolysis indicates that a discriminating antigenreceptor molecule must be Involved, but attempts to identify this T cell receptor have met with only limited success. In addition to an antigen-specific receptor, other cell surface molecules appear to participate in the cytoiytic process. Antisera reactive with cell surface components have been utilized in attempts to define the molecules involved in cytolysis. Several investigators (Nakayama et al. 1979, Shinohara & Sachs 1979) demonstrated that anti-Lyl-2 alloantisera couid inhibit cytolysis mediated by T cells obtained from immunized animals or from mixed lymphocyte cultures (MLC). However, the interpretation of these results was complicated by the fact that such antisera may have contained antibodies which reacted with other antigens. In addition, it was difficult to be
