| Popis: | The suppression fo the anti-NIP ((4-hydroxy-5-iodo-3-nitrophenyl)acetyl) plaque-forming cell (PFC) response elicited in mice by treatment with NIP-coated syngeneic erythrocytes could be transferred by spleen cells into irradiated recipients. This was evidenced by the lack of an indirect anti-NIP PFC response 7 days after cell transfer and challenge with NIP. FGG (fowl IgG). This state of specific unresponsiveness could be serially transferred by spleen cells into a second irradiated recipient. The hapten-specific suppression in the first recipient could be reversed by addition of normal spleen cells, but not by cortisone-resistant thymus cells. The lesion appears to be in the T cell-depleted population, since the suppression could be reversed by supplementing with T cell-depleted normal spleen cells. In vitro incubation of spleen cells from tolerant animals did not restore the capacity of these cells to produce an anti-NIP PFC response in irradiated recipients. In vitro incubation of normal spleen cells with sera from tolerant animals did not prevent these spleen cells from producing a normal anti-NIP PFC response in irradiated recipients. The adoptive secondary response response to NIP. FGG was inhibited by injection of NIP-coated syngeneic erythrocytes on the same day as the adoptive transfer of the NIP. FGG primed spleen cells and the challenging antigen. It would seem that NIP-coupled syngeneic erythrocytes, which are presumably poor stimulators of T cells, can suppress NIP-specific B cells, perhaps by gaining direct access to the surface of these cells. |
