[Effect of trypsin on suppressor cell formation and function in localized staphylococcal infection].
The present study has been made on (CBA X C57BL)F1 mice immunized with sheep red blood cells (SRBC) and inoculated with staphylococci (M-SRBC-S). The injection of splenic lymphocytes from syngeneic M-SRBC-S into intact mice has been found to suppress immune response to SRBC in these mice. The injection of trypsin into M-SRBC-S decreases the suppressive action of their lymphocytes on SRBC-induced immune response in syngeneic recipients. The injection of trypsin into the recipients has been found to produce no effect on the immunosuppressive action of transplanted lymphocytes obtained from M-SRBC-S. The injection of trypsin into M-SRBC-S induces the release of the factor, inhibiting the formation and function of suppressor cells, by their splenocytes. Previously formed suppressor cells block the release of the immunostimulating factor by the splenocytes of the animals receiving the injections of trypsin.
