General description
C-C chemokine receptor type 8 (UniProt: P56484; also known as C-C CKR-8; CC-CKR-8; CCR-8, CDw198) is encoded by the Ccr8 (also known as Cmkbr8, Ter1) gene (Gene ID: 12776) in murine species. CCR8, a member of the G-protein coupled receptor 1 family, is a multi-pass membrane protein with four extracellular domains, seven transmembrane domains, and four cytoplasmic domains. Its expression is observed in thymus and its higher expression is observed in Treg and T helper 2 (TH2) cells. It is recruited to the inflammation site and has been implicated in allergy and asthma. It serves as a receptor for CCL1/SCY1 chemokine. In human and in murine models CCR8+ Tregs account for 30 to 80% of tumor Tregs in various cancers and only less than 10% in other tissues. However, most tumor-infiltrating conventional T cells are reported to be CCR8 negative. Disruption of CCR8 function is reported to result in reduced accumulation of Treg cells within tumors and disrupts their immunosuppressive function. (Ref.: Kidani, Y., et al. (2022). Proc. Natl.
