CCR6 and diffuse large B-cell lymphoma: Regarding the two members of the B-cell homeostatic chemokine receptors [11,12,13], CCR6 and CCR7, we observed a 7-fold higher CCR6 expression in tFL (Figure 1, p = 0.038), and at least a 5-fold higher CCR7 expression in GCB- and NGCB-DLBCL, tFL, and RS compared with controls (Figure 1, p < 0.028).
