  • Title: T cell hybrids with arsonate specificity. I. Initial characterization of antigen-specific T cell products that bear a cross-reactive idiotype and determinants encoded by the murine major histocompatibility complex.
    Author: Pacifico A, Capra JD.
    Journal: J Exp Med; 1980 Nov 01; 152(5):1289-301. PubMed ID: 6159448.
    Abstract:
    T cell hybrids have been constructed between the BW5147 thymoma cell line and A/J splenocytes from mice suppressed with the p-azophenylarsonte hapten. Three independently derived cloned lines have been chracterized. Each secretes or sheds a 62,000-dalton antigen-specific product bound by rabbit antisera directed against the arsonate cross-reactive idiotype. In addition, each of the antien-specific molecules contains determinants encoded within the I region of the murine major histocompatibility complex. Peptide mapping analysis indictes that, whereas these molecules are remarkably similar, each is individually distinct in primary structure. The availability of cloned T cell lines that produce antigen-specific idiotype-positive I region-containing products should facilitate a more thorough dissection of the interrelationships of T-B interctions in the arsonate idiotypic system.
