CCR1 and diffuse large B-cell lymphoma: Although we used a small number of the lymphoma samples of the different subgroups, we reported that all of the investigated activation-induced chemokine receptors –CCR1–CCR5, CCR8, CCR9, CXCR1, CXCR2, CXCR6, CXCR7, CX3CR1, and XCR1—as well as two of the five investigated B-cell homeostatic chemokine receptors –CCR6 and CCR7—were more highly expressed in at least NGCB-DLBCL, GCB-DLBCL, and tFL compared with GC-B.
