  • Title: [Production of heterologous antibodies to T-killers of mice immunized against H-2 antigens].
    Author: Egorova SG, Gritsman AIu, Brondz BD.
    Journal: Biull Eksp Biol Med; 1980 Jul; 89(7):62-4. PubMed ID: 6157432.
    Abstract:
    Rabbit antisera were obtained against cytotoxic small peritoneal lymphocytes (IPEL) of CBA (H-2k) mice immune to alloantigens C57BL/6 (H-2b) and to the enriched 5-day MLC cytotoxic blast lymphocytes (MLC--CL). After appropriate absorption by cells and tissues of intact mice the cytotoxicity of the sera was lost relative to normal lymphoid cells. The absorbed anti-CPL serum inhibited, in the presence of complement, the cytotoxic effect of CPL but not that of MLC--CL on 51Cr-labeled allogeneic macrophages. This inhibition was restricted by idiotypic and strain specificity. Conversely, the absorbed anti-MLC--CL serum inhibited the cytotoxic effect of both CPL and MLC--CL of various mouse strains, irrespective of their immunologic specificity. It is supposed that the effect of the anti-CPL serum is mainly caused by antibodies againts idiotypic determinants of the killer T receptors, whereas the effect of the anti-MLC--CL serum is due to antibodies against differentiation antigens of the proliferating lymphocytes.
