Abstract
Antigen-specific I region-restricted, interleukin 2-producing T cell hybridomas were produced by fusing GAT-specific T cell blasts with BW5147. Two antigen-specific phenotypes were identified, one autoreactive and one nonautoreactive. All of the antigen-specific and autoreactive clones were H-2 restricted, mapping to the IA subregion by genetic analysis and monoclonal antibody inhibition. Both the antigen-specific and autoreactive stimulation are the property of a single cell and required no known exogenous antigens.
