Prostaglandin transporter in the rat brain: its localization and induction by lipopolysaccharide.

Prostaglandin E2 (PGE2) is produced in the brain during infectious/inflammatory diseases, and it mediates acute-phase responses including fever. In the recovery phase of such diseases, PGE2 disappears from the brain through yet unidentified mechanisms. Rat prostaglandin transporter (PGT), which facilitates transmembrane transport of PGE2, might be involved in the clearance of PGE2 from the brain.
