Abstract

CpG oligodeoxynucleotides (CpG ODN) are known to elicit Th1 immune responses via TLR9. However, the precise mechanisms through which B cells are involved in this phenomenon are not fully understood. We investigated the effect of CpG ODN on the induction of Th1-chemoattractant CXCR3 chemokines, IP-10, Mig, and I-TAC, in B cells. Cells from the RPMI 8226 human B cell line and human peripheral B cells were stimulated with three distinct classes of CpG ODN. As a result, CXCR3 chemokines were strongly up-regulated by CpG-B and CpG-C, but only weakly by CpG-A. Though CXCR3 chemokines are known to be induced by IFNs, blocking mAbs against IFN receptors did not inhibit their induction by CpG-B. Induction of CXCR3 chemokines was blocked by two NF-κB inhibitors and a p38 inhibitor. These results strongly suggest that CXCR3 chemokines are directly induced by CpG ODN via NF-κB- and p38-dependent pathways in human B cells.
