Antigen-presenting hybridoma cells expressing MHC antigens of the LEW rat

Towards the eventual purpose of facilitating analyses of specificities and functions of LEW rat T lymphocytes involved in the induction and development of organ-specific autoimmune disorders, hybridoma cells expressing class I and class II MHC antigens of LEW rat have been developed. B cell hybridomas produced between a murine B cell tumor M12.4.5 and stimulated LEW B cells expressed high levels of LEW class II MHC antigen but the expression of LEW class I MHC antigens on these cells was rather low. The B hybridoma cells were capable of presenting soluble protein antigens to LEW CD4+ T cells. Furthermore, The use of this hybridoma revealed antigen-specific cytolytic activity of rat CD4+ T cells. T cell hybridomas produced between murine thymoma BW5147 and LEW T cells expressed class I MHC antigens of the LEW rat. The expression was confirmed by surface staining and specific cytolysis by rat allogeneic CTL.
