In human breast cancer, RNA‐seqencing analyses of tumour‐infiltrating CD4+ CD25+ Treg cells revealed high expression of the genes encoding the chemokine receptors CCR5, CCR8, CCR10, CX3CR1, CXCR3 and CXCR6 compared with blood CD4+ CD25+ Treg cells.70 Among these, some were also shared with tumour‐infiltrating Tconv cells (CCR5, CXCR3 and CXCR6), suggesting that Treg cells may employ both unique and shared pathways to migrate to breast tumour lesions. The gene discussed is CCR10; the disease is neoplasm.
