Prostaglandins (PGs) play important roles in diverse physiological processes in the central nervous system. PGD2is the most abundant PG in the brain and acts through specific receptors, DP1 and CRTH2. We investigated the effects of PGD2on the morphology of the hypothalamic cell line mHypoE-N37 (N37). In N37 cells, serum starvation induced neurite outgrowth and PGD2elicited neurite retraction, although we failed to detect transcripts for DP1 and CRTH2. Such an effect of PGD2was efficiently mimicked by its metabolite, 15-deoxy-Δ12,14-prostaglandin J2. N-acetyl cysteine completely abolished the effect of PGD2, and reactive oxygen species (ROS) were considered to be important. Notably, neurite outgrowth was restored by PGD2removal. These results suggest that PGD2induces reversible neurite retraction in a ROS-mediated mechanism that does not involve any known receptor.
