Studies on tolerance induction in vitro. I. Production of immunologically tolerant rabbit spleen cells and the transfer of tolerance to untreated cells.
Tolerance was induced in rabbit spleen cells by incubation with solubilized T2 phage (S-T2)2 at 37degrees C. Spleen cells thus treated maintained normal responsiveness to an unrelated antigen, S-SP82. Transfer of tolerance was demonstrated in in vitro in that the addition of washed tolerant cells caused suppression of the response of untreated cells to an immunogenic dose of S-T2. Evidence is presented that this suppression is not due to the transfer of tolerogenic quantities of antigen. Spleen cell populations depleted of adherent cells were still capable of being made tolerant and of transferring tolerance.
