Expression frequencies of CCR2, CCR3, CCR9, and CXCR5 on T lymphocytes were lower in CRC tissue as compared with normal tissue. Percentages of CCR2+ (a), CCR3+ (b), CCR9+ (c), and CXCR5+ (d) cells among CD4+ (closed circles) and CD8+ (open circles) T lymphocytes isolated from colonic carcinoma tissue compared with unaffected colonic mucosa. Data points from the same patient for CD4+ or CD8+ T lymphocytes, respectively, are connected
