前列腺素类是由前列腺素(PGs)和血栓素(TXs)组成的一类脂质介质,在各种刺激下形成。包括PGD2、PGE2、PGF2α、PGI2和TXA2。它们在合成后立即释放到细胞外,并通过与靶细胞表面上的G蛋白偶联的视紫红质型受体结合来发挥其作用。从小鼠到人,哺乳动物中保守的前列腺素受体有八种类型。它们是PGD受体(DP)、PGE受体的四种亚型(EP 1、EP 2、EP 3和EP 4)、PGF受体(FP)、PGI受体(IP)和TXA受体(TP)。最近,这些前列腺素受体中的每一种都有缺陷的小鼠被产生并经受各种疾病的实验模型。这些研究揭示了PG受体信号传导在各种病理状况中的作用,并表明前列腺素类受体的选择性操纵可能有益于治疗病理状况。在这里,我们回顾了前列腺素受体信号转导的作用及其治疗意义的这些最新发现。
Prostanoids, consisting of the prostaglandins (PGs) and the thromboxanes (TXs), are a group of lipid mediators formed in response to various stimuli. They include PGD2, PGE2, PGF2α, PGI2, and TXA2. They are released outside of the cells immediately after synthesis, and exert their actions by binding to a G-protein coupled rhodopsin-type receptor on the surface of target cells. There are eight types of the prostanoid receptors conserved in mammals from mouse to human. They are the PGD receptor (DP), four subtypes of the PGE receptor (EP1, EP2, EP3, and EP4), the PGF receptor (FP), PGI receptor (IP), and TXA receptor (TP). Recently, mice deficient in each of these prostanoid receptors were generated and subjected to various experimental models of disease. These studies have revealed the roles of PG receptor signaling in various pathological conditions, and suggest that selective manipulation of the prostanoid receptors may be beneficial in treatment of the pathological conditions. Here we review these recent findings of roles of prostanoid receptor signaling and their therapeutic implications.
