Abstract

Spleen cells were treated with TNBS in order to determine if cell surface H-2 antigens are derivatized with TNP. By labeling the cell membrane of the TNP-modified cells with 125I, followed by detergent lysis and immune precipitation with anti-TNP, it was determined that no H-2 antigenic activity remained in the supernatant. Further, by the use of an antibody-induced antigen redistribution assay it was found that previous exposure of TNP-modified cells to anti-TNP in the absence of complement rendered these cells resistant to lysis by anti-H-2 in the presence of complement. Together these data indicate that at the concentration of TNBS used for modification, H-2 antigens are derivatized with TNP. However, in addition to H-2, other proteins including immunoglobulin were also derivatized with TNP. Anti-TNP cytotoxic effector cells were blocked from their cytotoxic activity by anti-TNP antiserum. These data indicate that TNP directly couples to H-2 antigens on the cell surface of TNP-modified cells and that TNP is associated with the antigenic determinant that the cytotoxic T cell recognizes.
