    Abstract:
    The optimal conditions are found for in vivo irradiated lymphocyte induction of high cytotoxic T lymphocytes (CTL) specific to the H-2Kb molecule with a subsequent monoculture differentiation. B10.D2(R101) CTL have a pronounced excess as compared to B10.A (4R) CTL, with respect to lysis intensity of the same target cells (TC), and requires a lower term of the monoculture incubation in spite of their specificity to the same H-2Kb molecule. As the susceptibility of TC for CTL lysis is higher (M phi as compared to EL-4 thymoma cells), CTL are much more inactivated with the monoclonal antibodies to Lyt-2 and Lyt-3 antigens without complement. Anti-H-2Kb CTL differentiated in the monoculture cross react to TC bearing third-party H-2 molecules (Kk, Dq, Dk). Unlike a stable CTL adherence to the donor M phi monolayer, nonspecific CTL adherence to the syngeneic M phi monolayer declines in the presence of EGTA, and as a result of repeated detachment of lymphocytes. The findings give rise to study receptor affinity expressed on the in vivo induced CTL surface, the CTL receptor monoclonal antibody and the CTL differentiation factor.
