Prostacyclin and Interaction with Diacylglycerol Lipase and CDP Diacylglycerol; Possibility of De Novo Synthesisof Prostacyclin or Related Congeners by Novel Mechanisms
Journal Title: IOSR Journal of Pharmacy and Biological Sciences (IOSR-JPBS) - Year 2017, Vol 12, Issue 3
Abstract
Prostacyclin is a strong cardioprotective hormone released by the endothelium of the blood vessels. Prostacyclin is present in equilibrium with several vasoactive agents in cardiovascular system. In recent years, prostacyclin (PGI2) has also been shown to enhance differentiation and inhibit proliferation in vascular smooth muscle cells. In addition to these well-described homeostatic roles within the cardiovascular system, prostacyclin (PGI2) also plays an important role as an inflammatory mediator. In this review, the focus on the contribution of prostacyclin (PGI2) as both a patho-physiological mediator in three major inflammatorymediated disease processes, namely rheumatoid arthritis, where it promotes disease progression , along with pulmonary vascular disease and atherosclerosis, where it inhibits disease progression. On the other hand, CDP-DAG synthases (CDS) are enzymes that catalyze the conversion of phosphatidic acid (PA) to CDPdiacylglycerol (CDP-DAG). Both PA and CDP-DAG serve critical roles in cellular functions.This article reviews the possibility of interaction with CDP diacylglycerol and it appears that de novo synthesis of PGI2 or its congeners occurs in specialized cells under patho-physiological conditions.
