More surprisingly, we found that NF-κB1-deficiency in OTII cells also selectively impairs CXCR5 induction by alumOVA without affecting upregulation of BCL6, IL-21, OX40 and CXCR4 mRNA and PD-1 protein. This results in functional impairment of follicular helper T (TFh) cells. Thus, fewer germinal center B cells develop in lymph node responses to alumOVA in T-cell-deficient mice reconstituted with NF-κB1OTII cells as opposed to NF-κB1(+/+) OTII cells, while plasma cell numbers are comparable. Unlike CXCR5 induction in CD4 T cells, NF-κB1-deficient recirculating follicular B cells are shown to express normal levels of CXCR5. The selective effects of NF-κB1-deficiency on Th2 and TFh induction does not appear to be due to altered expression of the Th2-associated transcription factors - GATA-3, c-Maf and Ikaros. Altogether, these results suggest that NF-κB1 regulates the expression of CXCR5 on CD4 T cells primed in vivo, and thus selectively controls the T-cell-dependent germinal center component of B-cell response to alumOVA.",
