Monoclonal antibody to SV40 T-antigen blocks lysis of cloned cytotoxic T-cell line specific for SV40 TASA
Abstract
The lysis of SV40-transformed target cells by a cloned cytotoxic T cell line (CTB6) that is SV40 TASA-specific and H-2Kb-restricted is blocked by a monoclonal antibody reactive with the SV40 T-antigen. The blocking is maximized at high antibody concentrations and low effector-to-target cell ratios. These data indicate that at least one antigenic determinant of the SV40 T-antigen molecule is expressed at the cell surface and is either recognized by this cytotoxic T lymphocyte or is proximate to that determinant recognized by this cytotoxic T lymphocyte.
