Background
| Function | High affinity receptor for the C-C type chemokines CCL17/TARC, CCL22/MDC and CKLF isoform 1/CKLF1. The activity of this receptor is mediated by G(i) proteins which activate a phosphatidylinositol-calcium second messenger system. Can function as a chemoattractant homing receptor on circulating memory lymphocytes and as a coreceptor for some primary HIV-2 isolates. In the CNS, could mediate hippocampal-neuron survival. |
| Subcellular Location | Cell membrane; Multi-pass membrane protein. |
| Tissue Specificity | Predominantly expressed in the thymus, in peripheral blood leukocytes, including T-cells, mostly CD4+ cells, and basophils, and in platelets; at lower levels, in the spleen and in monocytes. Detected also in macrophages, IL-2-activated natural killer cell |
| Protein Family | G-protein coupled receptor 1 family |

PMID: 28869080 This review presents key clinical studies of Multiple sclerosis together with experimental studies in animals that have demonstrated functional roles of CCR4, CCL17, and CCL22 in experimental autoimmune encephalomyelitis pathogenesis. [review] PMID: 29099057 Taken together, our data showed a likely positive feedback mechanism of enhanced IL-6 production in ectopic milieu. The high levels of IL-6 in the peritoneal cavity stimulate the expression of CCL17 in endometrial stromal cells by activating JNK signal pathway, and then, CCL17 further induces CCR4 expression on macrophages, which eventually leads to an increase in IL-6 production via NF-kappaB activation. PMID: 28240436 Investigations showed that the level of CCR4 could be induced by TNF-alpha dependent of NF-kappaB activation in CRC cells. CCR4 might be implicated in TNF-alpha-regulated cancer cells metastasis.
