CXCR6 and diffuse large B-cell lymphoma: Comparing the chemokine receptor expression profiles between the different lymphoma subtypes, we observed a remarkably higher expression of CCR1, CCR5, CCR8, CXCR6, CXCR7, and CX3CR1 (42-fold, 123-fold, 51-fold, 20-fold, 21-fold, and 4-fold higher expression) in both DLBCL-subtypes and tFL compared with RS (Figure 1 and Figure 2, p < 0.045).
