Chemerin is a distant member of the cystatin protein family, initially discovered as a chemotactic factor and subsequently also reported to act as adipokine and angiogenetic factor. The biological activity of chemerin is regulated at different levels, such as gene expression, protein processing, and interaction with both signaling and nonsignaling receptors. Chemerin is mostly produced by stromal cells, such as adipocytes, fibroblasts, and epithelial and endothelial cells, and circulates in almost all human tissues as a zymogen that needs to be proteolytically activated to exert its biological functions. At the receptor level, chemerin binds a G protein-coupled 7-transmembrane domain receptor Chemerin1 (also named ChemR23 and CMKLR1), mostly expressed by innate immune cells, such as macrophages, dendritic cells, and natural killer cells, and by border cells. In addition, chemerin may bind GPR1, a weak signaling receptor, and CCRL2, a nonsignaling receptor expressed by barrier cells, such as endothelial and epithelial cells, able to regulate leukocytes' migration by multiple mechanisms. The aim of this review is to summarize the contribution of chemerin in the regulation of immune responses.

Abstract

Chemerin is a distant member of the cystatin protein family, initially discovered as a chemotactic factor and subsequently also reported to act as adipokine and angiogenetic factor. The biological activity of chemerin is regulated at different levels, such as gene expression, protein processing, and interaction with both signaling and nonsignaling receptors. Chemerin is mostly produced by stromal cells, such as adipocytes, fibroblasts, and epithelial and endothelial cells, and circulates in almost all human tissues as a zymogen that needs to be proteolytically activated to exert its biological functions. At the receptor level, chemerin binds a G protein-coupled 7-transmembrane domain receptor Chemerin1 (also named ChemR23 and CMKLR1), mostly expressed by innate immune cells, such as macrophages, dendritic cells, and natural killer cells, and by border cells. In addition, chemerin may bind GPR1, a weak signaling receptor, and CCRL2, a nonsignaling receptor expressed by barrier cells, such as endothelial and epithelial cells, able to regulate leukocytes' migration by multiple mechanisms. The aim of this review is to summarize the contribution of chemerin in the regulation of immune responses.
