Regulation of atherogenesis by chemokine receptor CCR6

Atherosclerosis is a complex vascular pathology characterized in part by accumulation of innate and adaptive inflammatory cells in arterial plaque. Molecular mediators responsible for inflammatory cell accumulation in plaque include specific members of the chemokine family of leukocyte chemoattractants and their G protein-coupled receptors. Studies using the ApoE knockout mouse model have recently implicated chemokine receptor Ccr6 and its ligand Ccl20 as a non-redundant ligand-receptor pair in atherosclerosis, potentially operating at several stages of cell recruitment and on several leukocyte subtypes.
