  • Title: In vitro studies of the rabbit immune system. VI. Rabbit anti-mouse cytotoxic T effector cells are inhibited by anti-rabbit T cell serum in the absence of complement.
    Author: Redelman D, Trefts PE.
    Journal: J Immunol; 1978 Oct; 121(4):1532-9. PubMed ID: 308967.
    Abstract:
    Xenogeneic rabbit anti-mouse cell-mediated cytotoxic activity could be generated by culturing lymphoid cells from mesenteric lymph nodes (MLN), spleen, or peripheral blood of rabbits primed 2 to 8 weeks earlier with mouse tumor or spleen cells. MLN cells, which provided the best source of activity after being cultured with 5 to 10 X 10(6) mitomycin C-treated mouse spleen cells for 4 to 6 days, produced 30 to 90% specific isotope release after 4 to 7 hr incubation with 15Cr-labeled tumor target cells. Xenogeneic cytotoxic activity was primarily H-2 specific and could not be blocked by immune complexes but was abrogated by treatment with goat anti-rabbit thymocyte serum plus complement (ATS + C) before or after culture. Therefore, the activity appeared to be mediated by cytotoxic T lymphocytes (CTL). Furthermore, ATS without C abrogated cytotoxic activity when included in the CTL assay at concentrations of 5 to 15 microliter/10(7) effector cells. The inhibitory activity of ATS was directed to the rabbit effector population and could be absorbed completely by rabbit thymocytes. Antisera to mouse T cells with comparable cytolytic activity in the presence of C did not inhibit murine allogeneic CTL.
