T lymphocytes from colorectal carcinoma tissue showed a distinct chemokine receptor expression profile compared to unaffected tissue. The bars show median chemokine receptor expression frequencies on human CD4+ (a–c) and CD8+ (d–f) viable T lymphocytes isolated from unaffected colonic mucosa (light gray bars) versus colonic carcinoma tissue (dark gray bars), as analyzed by flow cytometry. The vertical lines represent the interquartile range (IQR). Wilcoxon test; *p < 0.05
