Lung tumor-reactive cytotoxic lymphocytes generated in mixed lymphocyte reaction between C3HfeB/HeN (H-2kb) and C3H/HeN (H-2k) strain mice.
The tumor-associated transplantation antigen expressed by several transplacentally induced lung tumors of C3HfeB/HeN mice (H-2kb haplotype) has previously been shown to exist as a normal tissue alloantigen in mice of known H-2k and H-2a haplotypes. This antigen is not expressed in normal tissues of C3HfeB/HeN mice but is expressed in C3H/HeN mice, the strain from which the C3HfeB/HeN mice were originally derived. The present study indicates that spleen cells from C3HfeB/HeN and C3H/HeN mice respond reciprocally in the mixed lymphocyte reaction. Cytotoxic T lymphocytes specific for the tumor-associated alloantigen can be readily generated in mixed lymphocyte reactions in which spleen cells from C3HfeB/HeN mice are reacted with x-irradiated spleen cells from C3H/HeN or A strain mice. These cells are effective in suppressing the growth of the C3HfeB/HeN-derived lung tumor 85 in x-irradiated syngeneic recipients.
