Chemerin receptors


The chemoattractant protein and adipokine, chemerin, has been shown to be the endogenous ligand for both chemerin family receptors. Chemerin1 was the founding family member, and when GPR1 was de-orphanised it was re-named Chermerin2 [1]. Chemerin1 is also activated by the lipid-derived, anti-inflammatory ligand resolvin E1 (RvE1), which is formed via the sequential metabolism of EPA by aspirin-modified cyclooxygenase and lipoxygenase [2,3]. In addition, two GPCRs for resolvin D1 (RvD1) have been identified: FPR2/ALX, the lipoxin A4 receptor, and GPR32, an orphan receptor [4].
