Abstract
Prostaglandin (PG) E2 is a well-established lipid mediator that plays a role in diverse functions and diseases of the brain. Cyclooxygenase and PGE synthase have been extensively studied as molecular determinants of extracellular concentration of PGE2 near prostanoid E receptors since the brain has limited capacity of PG metabolism. There is accumulating evidence that several members of the solute carrier (SLC) and ATP-binding cassette (ABC) superfamilies regulate PGE2 distribution in brain capillary endothelial cells, choroid plexus (CP) and arachnoid epithelium, and different parenchyma cells such as neuronal and glial cells. These transporters may mediate entry and exit of PGE2 at blood-brain and blood-cerebrospinal fluid boundaries, resulting in brain distribution of PGE2. However, their roles in neuroinflammation and disease progression remain unclear. In this review, current knowledge on transporters involved in brain distribution of PGE2 is summarized, and especially, potentials of organic anion transporting polypeptide (OATP) and organic anion transporter (OAT) family members are discussed as molecular determinants of PGE2 concentration in the brain.
