GPR18 Receptor Antibodies
GPR18 (G Protein-Coupled Receptor 18) is an orphan GPCR that is believed to respond to lipid-based ligands, including N-arachidonoyl glycine (NAGly), a metabolite related to endocannabinoids. While its endogenous ligand remains under debate, GPR18 is functionally associated with immune modulation and inflammation. GPR18 is expressed in various tissues, with high levels in immune cells such as T cells, B cells, macrophages, and microglia. It is also found in the spleen, thymus, testis, and certain regions of the central nervous system, including the brainstem and hypothalamus. GPR18 is considered a potential pharmacological target due to its roles in immune regulation, inflammation, pain, and cancer progression. It has been implicated in processes such as immune cell migration, neuroinflammation, and tumor cell survival. For more information on GPR18 pharmacology please refer to the IUPHAR database.
