GPR75: A Newly Identified Receptor for Targeted Intervention in the Treatment of Obesity and Metabolic Syndrome

Metabolic syndrome increases the risk of stroke, cardiovascular disease, and diabetes. The morbidity and mortality associated with this constellation of risk factors are equally alarming when considering the economic and global significance that this epidemic has on an institutional and patient level. Despite several current treatments available, there needs to be a continuous effort to explore more specific and effective druggable entities for preventative and therapeutic interventions. Within this context, the G-protein coupled receptor, GPR75, is an attractive pharmacological target. GPR75 and its association with its ligand, 20-hydroxyeicosatetraenoic acid, have been shown to promote hypertension, inflammation, obesity, and insulin resistance. This review will help shed light on this novel signaling pathway and offer a perspective on a promising new direction of targeting different aspects of the metabolic syndrome involving GPR75. Gene targeting of GPR75 is more effective than current pharmacologic therapies without the known side effects.
