Mouse CCR4 cDNA contains 1531 bp, and encodes a protein of 360 amino acids that is 85% identical to human CCR4. CCR4 binds CCL17 (TARG) and CCL22 (MDC). Naïve T cells, bearing receptors for cutaneous antigens, become activated in skin-draining lymph nodes and express cutaneous lymphocyte antigen (CLA), which confers to these cells the capacity to migrate into the skin to exert their normal effector functions (1). CCR4 and CCR10 play an important role in the ligand-mediated recruitment of T cells into the skin in mice and humans, specifically with regards to tethering, firm adhesion, and subsequent extravasation to the site of injury (2,3). CCR4 is expressed in cutaneous regulatory T cells (Tregs). These cells are crucial for the induction and maintenance of self-tolerance and are present in peripheral tissues such as skin and gut under normal, noninflamed conditions (4).In addition, recruitment of Foxp3+ T regulatory cells mediating allograft tolerance depends on the CCR4 chemokine receptor and its ligand CCL22 (5).

Other Names: CC CKR-4, CHEMR1, Cmkbr4, LESTR, MGC151418, Sdf1r
Structure: GPCR, chemokine receptor, seven transmembrane receptor
Distribution: Memory T cells, macrophages, platelets, basophils, Th2 cells, and Tregs
Function: CCR4 and its ligands (CCL17 and CCL22) are important for the recruitment of memory T cells into the skin in various cutaneous immune diseases.
Ligand Receptor: CCl17 and CCL22
Interaction: Interaction between CCR4 and its ligand TARC/CCL17 on activated endothelial cells mediates T cell extravasation by stimulating integrin-dependent adhesion
