We have utilized cloned T cell reagents and ionizing radiation-induced mutants of an HLA heterozygous lymphoblastoid cell line (LCL) to investigate the determinants detected by the cell-mediated lympholysis (CML) assay. Cells of an LCL clone, 721.501, an HLA haplotype loss mutant expressing the HLA-A2-Cw1-Bw51-DR1-Dw1-DQw1-DPw2-GLO haplotype were used as sensitizing cells for responder cells in vitro. "Cloned" reagents were generated by single-cell deposition of cells of a bulk reagent primed against 721.501 cells. Those clones were screened for cytolytic activity against HLA loss mutant targets (derived from LCL 721) of four different categories; HLA-A2 loss only, A2-Cw1-Bw51 loss, A2-Cw1-Bw51-DR1-DQw1 loss, and the entire HLA haplotype loss. Of 196 clones tested, 36 were cytolytic, including three anti-A2, five anti-Bw51/Cw1, 12 anti-DR1/DQw1, 13 anti-DP region associated with DPw2, and three of undetermined specificity, based on cytolytic patterns against the HLA loss mutant targets. Of 25 anti-HLA class II lytic clones, 23 (92%) fitted the characteristics of helper cell-independent cytolytic T cells (HITc), whereas only two of eight (25%) anti-class I clones were HITc. The 13 anti-DP region clones were divided into three subgroups defined by blocking by anti-FA and not Tü39 monoclonal antibodies (MoAb), by Tü39 and not anti-FA, and by both MoAbs.
