摘要:The distribution of prostaglandin D synthetase activity was determined in various tissues of rat by using the supernatant fraction (10,000 x g, 20 min) of the homogenates. The highest activity was found in brain, spinal cord, and alimentary tract. The activity was uniquitously distributed in all parts of brain, and the highest specific activity was found in hypothalamus and thalamus. Homogenates of two neuroblastoma cell lines were found to produce prostaglandin D2, whereas a glioma cell line was almost inactive. Prostaglandin D2 is a potent and specific activator of the adenylate cyclase system of cultured neuroblastoma cells, suggesting the possibility that it may act as a neuromodulator in the central nervous system.
