ChemR23/CMKLR1
ChemR23/CMKLR1 is a G protein-coupled chemerin receptor that mediates calcium mobilization and chemotaxis in immature dendritic cells and macrophages[1]. Mechanistically, chemerin and resolvin E1 activate ChemR23/CMKLR1 to regulate leukocyte trafficking and inflammation-resolution programs[2][3]. In macrophage biology, ChemR23 is functional on M1 macrophages, where chemerin induces chemotaxis, but it is not surface-expressed on M2 macrophages[3]. Compared with related chemerin receptors, CMKLR1/Chemerin1 and GPR1/Chemerin2 both respond to processed chemerin, whereas CCRL2 binds chemerin without classical signaling, supporting distinct experimental interpretation of receptor isoforms[4][5]. In disease models, ChemR23-dependent chemerin activity suppresses inflammation in lung injury, while synthetic chemerin-derived peptides suppress zymosan-induced peritonitis through ChemR23[6]. For experimental applications, the small-molecule antagonist CCX832 selectively blocks CMKLR1, and chemerin-derived peptides or resolvin E1 provide agonist tools for studying CMKLR1-driven immune-cell recruitment, inflammation resolution, and receptor-selective signaling[5][6].

VU0514009
0 ImagesVU0514009 is a competitive chemokine-like receptor 1 (CMKLR1) antagonist (EC50=2 nM). VU0514009 prevents chemerin-9-induced arrestin recruitment and receptor internalization, significantly reducing Ca2+ flux response in HEK293 cells. VU0514009 is promising for research of inflammatory diseases and metabolic syndrome.
