Abstract:
:A monoclonal antibody, B20.1, was generated by fusing spleen cells from a Lou rat immunized with a soluble alpha/beta T cell receptor (TcR; V alpha 2/V beta 2) to mouse myeloma cells. Analysis of a panel of V alpha 2 mRNA-expressing T cell lines, hybridomas and transfectants revealed that the B20.1 antibody was specific for murine TcR V alpha 2 chains. The V alpha 2+ T cell population was examined in various inbred strains by two-color immunofluorescence using B20.1 and CD4- and CD8-specific antibodies with the following results: (a) the B20.1 antibody detected most members of the TcR V alpha 2 subfamily in the four TcR V alpha haplotypes tested; (b) in most strains examined, TcR V alpha 2 expression was biased to the CD4 subset (7.4%-17.4% V alpha 2+ T cells) as compared to the CD8 compartment (3.8%-13.3%); (c) TcR V alpha 2 expression was not influenced by Mls gene products and (d) increased positive selection of V alpha 2+ CD8+ T cells by H-2k major histocompatibility complex molecules occurred in all murine strains tested of the TcR V alpha a, but not in those bearing the TcR V alpha b haplotype.

杂志文章abstract::The role of TGF-beta1 in the regulation of T cell responses has been perplexing, possibly because it is dependent on the type of T cell being regulated and its cytokine microenvironment. In the present study, we demonstrate that TGF-beta1 has a profound inhibitory effect on naive CD4+ T cell undergoing differentiation...
