CCRL2 (C-C chemokine receptor-like 2) is a seven transmembrane, G-protein coupled receptor with two isoforms generated from alternative splicing. CCRL2 is expressed by the majority of cell types of hematopoietic origin, including monocytes, macrophages, neutrophils, lymphocytes, and NK cells. In some cell types, its expression is upregulated by inflammatory stimuli. CCRL2 is important for the development of Th2 responses and may act as a decoy receptor capturing and endocyting its ligands CCL5 and CCL19; however, it has been found that CCRL2 captures and retains chemerin/RARRES2 on its cell surface, presenting it to neighboring cells.
