In the group of CXCR, CX3CR1, and XCR1 chemokine receptors, five activation-induced chemokine receptors [8], CXCR1, CXCR2, CXCR6, CX3CR1, and XCR1 were expressed at least 27-fold more highly in GCB-DLBCL, NGCB-DLBCL, and tFL, compared with GC-B (Figure 2, p < 0.043). Here, CXCR2 is linked to diffuse large B-cell lymphoma.
