前列腺素类是生物活性的脂质介质,并且几乎在每个器官、组织和细胞(包括血管、肾、胃肠道和生殖系统)中参与许多生理和病理生理过程。在这篇综述中,我们重点关注它们对血小板的影响,血小板是血栓形成和止血的关键因素。血小板的功能受血液和血管壁中介质的影响。活化的血小板聚集并释放生物活性物质,从而进一步活化血小板,最终导致血栓形成。前列腺素类通过激活或抑制来调节血小板的功能,因此参与止血。每种前列腺素类都有独特的活性特征,因此具有特定的作用特征。本文综述了前列腺素类化合物前列腺素D2(PGD2)、前列腺素E1、前列腺素E2和前列腺素E3(PGE1、PGE2、PGE3)、前列腺素F2α(PGF2α)、前列环素(PGI2)和血栓素A2(TXA2)通过各自的受体对血小板活化和聚集的影响。
Prostanoids are bioactive lipid mediators and take part in many physiological and pathophysiological processes in practically every organ, tissue and cell, including the vascular, renal, gastrointestinal and reproductive systems. In this review, we focus on their influence on platelets, which are key elements in thrombosis and hemostasis. The function of platelets is influenced by mediators in the blood and the vascular wall. Activated platelets aggregate and release bioactive substances, thereby activating further neighbored platelets, which finally can lead to the formation of thrombi. Prostanoids regulate the function of blood platelets by both activating or inhibiting and so are involved in hemostasis. Each prostanoid has a unique activity profile and, thus, a specific profile of action. This article reviews the effects of the following prostanoids: prostaglandin-D2 (PGD2), prostaglandin-E1, -E2 and E3 (PGE1, PGE2, PGE3), prostaglandin F2α (PGF2α), prostacyclin (PGI2) and thromboxane-A2 (TXA2) on platelet activation and aggregation via their respective receptors.
