Monoclonal antibodies specific for single chain or two chain GAT-specific suppressor factors: production and analysis of in vitro modulating properties.
Fusion of spleen cells from rats hyperimmunized with T cell hybridoma derived GAT-specific TsF1 or TsF2 suppressor T cell factors has resulted in the generation of hybridomas secreting monoclonal antibodies reactive with the appropriate GAT-TsF used for immunization, and in several cases, reactive with other GAT-TsF1 and TsF2. The monoclonal anti-TsF1 antibodies are capable of modulating in vitro GAT-specific PFC response in a GAT-specific manner; some suppress responses to GAT directly, whereas others reverse GAT-TsF1-mediated suppression of responses. The monoclonal anti-TsF2 antibodies all reverse suppression but are reactive with combinatorial determinants, I-J+ chains or antigen-binding chains of the GAT-TsF2. The data are discussed in terms of the nature of the determinants recognized by these antibodies as well as the potential uses of these reagents for studying the suppressor T cell pathway and potential relationships between Ts1, Ts2, and T helper cells.[1]References
