Abstract

B cell hybridomas expressing class I and II MHC molecules and producing antibodies directed against hemagglutinin protein of Rinderpest virus and human Mucin-1 have been used as surrogate B cells to study T cell responses against the antigens. The observed CTL and lymphoproliferative response indicates that anti-idiotypic B cells termed Jerne cells stimulate both T helper and T cytotoxic cells by virtue of their ability to present recycled or regurgitated peptido-mimics of antigen to T helper cells through class II MHC and de novo synthesized peptido-mimics of antigens to CTLs. Thus, T cell memory response can be perpetuated by anti-idiotypic Jerne B cells and these findings lend support to the earlier proposed relay hypothesis for perpetuation of immunological memory (IM).
