Using 50% WT CD45.1 (BoyJ) BM mixed with 50% either WT CD45.2 (B6) BM or Bcl6 cKO CD45.2 BM, we determined that the BM proportions were correct and that, after food allergy sensitization, roughly ~50% of each type of TFH and TFR cell developed in the WT(BoyJ):WT(B6) BMCs (Supplemental Figure 4, B and C). Here, TFRC is linked to food allergy.
