These chemokines (CXCL9, CXCL10, CXCL11, CXCL13, CCL2, CCL3, CCL4, CCL5, and CCL21) and their receptors (CCR1, CCR2, CCR5, CCR6, and CXCR3) show a positive correlation with CLEC1B, indicating that CLEC1B plays a pivotal role in the recruitment of CD8 + T cells, TH17 cells, antigen-presenting cells, and other tumor-infiltrating immune cells [57]. This evidence concerns the gene CCL5 and neoplasm.
