Percentage of B220⁺PNA⁺ cells after transfer of indicated combinations of T and B cells into Rag1^−/− mice followed by immunization with SRBCs. B220⁺PNA⁺ cells were evaluated 7 d after immunization by flow cytometry. P values are as follows: WT T+WT B vs. Def6^tr/tr T+WT B, NS; WT T + S70^−/− B vs. Def6^tr/tr T + S70^−/− B, P < 0.005; WT T + Def6^tr/tr B vs. Def6^tr/tr T + Def6^tr/tr B, P < 0.05; WT T + DKO B vs. Def6^tr/tr T + DKO B, P < 0.01; WT T+WT B vs. WT T + S70^−/− B cells, P < 0.005; WT T + WT B vs. WT T + Def6^tr/tr B cells, P < 0.05; WT T + WT B vs. WT T + DKO B cells, P < 0.005; Def6^tr/tr T + WT B vs. Def6^tr/tr T + S70^−/− B cells, NS; Def6^tr/tr T + WT B vs. Def6^tr/tr T + Def6tr/tr B cells, P < 0.01; Def6^tr/tr T + WT B vs. Def6^tr/tr T + DKO B cells, P < 0.005.
