T cell independent induction of antigen specific suppression of the antibody response.
Immune spleen cells (from mice given 2 x 10(7) HRBC 14 days earlier) when mixed in vitro with carrier-primed syngeneic spleen cells (from mice given 2 x 10(5) HRBC 3 days earlier) are able to suppress the anti-TNP and anti-HRBC PFC response to TNP-HRBC. If immune thymocytes are substituted for spleen cells suppression is not observed. This suppression is antigen specific, resistant to anti-T treatment or x-irradiation, and is exerted by nylon wool-retained cells of the immune spleen cell population. An antigen specific suppressive factor is released from immune spleen cells in culture. Under these experimental conditions, suppression appears to be mediated by a specific product of B rather than T cells present in the immune spleen cell population.
