Abstract

Spleens from mice primed with tetanus toxoid 30 days earlier contain memory cells capable of adoptively transferring secondary type cell mediated (eosinophil) and humoral (antitoxin) responses to irradiated, reconstituted recipients. Spleen cells derived from 10 day primed donors, on the other hand, possess the capacity after transfer to elicit secondary type eosinophil responses, but not anamnestic antitoxin responses. Treatment of 30 day primed cells with anti serum and C prevented transfer of memory for both responses, whereas similar treatment with rabbit anti mouse IgG (RAM IgG) serum and C only inhibited transfer of memory for the antitoxin response. Addition of non primed spleen cells to antisera treated primed cells failed to restore secondary type responses. Recombination of 30 day primed anti theta and RAM IgG treated cells reestablished the capacity to transfer these responses. To determine whether the same T cells which mediate the eosinophil response also act as helper cells in antitoxin production, antisera treated 10 and 30 day primed cells were combined prior to transfer. Ten day primed T cells induced eosinophil responses and also cooperated with 30 day primed B cells to produce antitoxin. In contrast, 30 day primed T cells elicited eosinophil responses, but were unable to induce antitoxin production when combined with anti theta treated 10 day primed cells. These results indicate that B memory cells are not present in the spleens of the donor mice 10 days after priming, but T memory cells are present. It is concluded that primed T cells mediated eosinophil and antitoxin responses, while B memory cells are involved only with antitoxin production. Following subcutaneous priming T memory cells are present in the spleen prior to B memory cells, and T memory cells which mediate the eosinophil response at 10 days after priming also augment the production of antitoxin by B memory cells.
