前列腺素在中枢神经系统的多种生理过程中发挥重要作用。PGD 2是大脑中含量最丰富的PG,通过特定受体DP 1和CRTH 2发挥作用。本研究观察了PGD 2对下丘脑细胞系mHypoE-N37(N37)形态学的影响。在N37细胞中,血清饥饿诱导神经突生长,PGD 2引起神经突收缩,尽管我们未能检测到DP 1和CRTH 2的转录本。PGD 2的这种作用可通过其代谢产物15-脱氧-Δ 12,14-前列腺素J2有效模拟。N-乙酰半胱氨酸完全消除了PGD 2的作用,活性氧(ROS)被认为是重要的。值得注意的是,PGD 2的去除恢复了神经突的生长。这些结果表明,PGD 2在ROS介导的机制,不涉及任何已知的受体诱导可逆的轴突回缩。
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.
