Chemokine receptor expression profiles differed between mucosal CD4⁺ and CD8⁺ T lymphocytes. The bars show median CC (a), CXC (b), and CX3C (c) chemokine receptor expression frequencies on human CD4⁺ (light gray bars) versus CD8⁺ (dark gray bars) viable lamina propria T lymphocytes isolated from normal colonic mucosa, as analyzed by flow cytometry. The vertical lines represent the interquartile range (IQR). Wilcoxon test; *p < 0.05
