Transcriptional profiling of human colorectal cancer (CRC) tissues revealed that active secretion of CCL5 and CXCL10 from the tumor microenvironment is closely associated with GZMB + CD8+ T cell infiltration, suggesting a critical role of CCL5 and CXCL10 in CTL recruitment [37]. Here, CCL5 is linked to colorectal carcinoma.
