CCL17 and neoplasm: As shown in Figure 6B and Supplementary Table S1, strong positive-correlations (r > 0.5, p < 0.05) were observed between the expression of CXCL10 and CCL5 and CD8+ T cell abundance in tumours, while CCL17 and CCL22 were negatively correlated (r < −0.5, p < 0.05) with CD8+ T cell infiltration.
