Ultraviolet light-induced murine skin tumors were analyzed for their ability to induce tumor-specific and cross-protective transplantation immunity in immunocompetent syngeneic mice. These studies revealed that progressor UV-tumors, like regressor UV-tumors, possess tumor-specific transplantation antigens. Cross-protective transplantation immunity to UV-tumors, however, was associated with sensitization to the serum used to culture the tumor lines rather than to cross-reactive or common determinants on UV-tumors. An analysis of the cytolytic activity of lymphocytes from the spleens of mice immunized with either regressor or progressor UV-tumors revealed a striking difference between the two immune splenocyte populations. From regressor tumor-immune animals, cytolytic T (Tc) lymphocytes with specificity for the immunizing tumor were found. However, the analysis of splenic lymphocytes from progressor tumor immune animals revealed no such effector cells. To more effectively examine those lymphocytes exhibiting cytolytic activity in vitro, T lymphocyte cloning technology was used as a means of isolating homogeneous lymphocyte populations with the effector activities described above. The mechanisms where NK cells and other nonspecific effector cells could be induced in tumor-immune animals are discussed in the context of class II restricted immune responses.
