Increased proportion of corresponding chemokine receptors (CCR)9⁺γδ T cells in Crohn's disease (CD) and ulcerative colitis (UC). Proportions of circulating γδ T cells in healthy controls (3·8 ± 1·4%, n = 11), active CD patients (27·4 ± 5·9, n = 8) and active UC patients (21·4 ± 9·2%, n = 7) expressing gut-homing marker CCR9; t-test was applied. A P-value < 0·05 was considered statistically significant (*P < 0·05; **P < 0·01; ***P < 0·001). Error bars represent standard error of the mean, horizontal lines represent mean.
