Summary of adoptive transfer experiments. (a) Experimental protocol for rescuing self-reactive B cells by means of antigen-specific T cell help. (b) Relative number of splenic H-2^bk (gray bars) and H-2^b (black bars) B cells 1 day after adoptive transfer. Values are normalized to the number of H-2^b B cells detected in the spleen on day 1 for each particular experiment. (c) Relative number of H-2^bk (gray bars) and H-2^b (black bars) splenic B cells 3 days after adoptive transfer. Values are normalized to the number of H-2^b B cells on day 1. (d) Ratio of H-2^bk to H-2^b splenic B cells 1 day (black bars) and 3 days (gray bars) after adoptive transfer. The experiments summarized in (b–d) are numbered according to the order in which they are described in the text.
