虽然结构简单,但溶血磷脂酸(LPA)是一种有效的生物活性脂质,其在与G蛋白偶联受体(LPA 1 -6)结合后深刻地影响细胞信号传导和功能。大部分循环LPA由分泌的自分泌运动因子(ATX)产生。LPA信号传导的改变,连同自分泌运动因子(ATX)表达和活性的变化,已经涉及代谢和炎性病症,包括肥胖症、胰岛素抵抗和心血管疾病。本文综述了LPA的来源和代谢,重点介绍了饮食对循环LPA的影响。此外,我们探讨了ATX-LPA通路如何影响肥胖和肥胖相关疾病,包括葡萄糖稳态受损,胰岛素抵抗和心血管疾病。
Although simple in structure, lysophosphatidic acid (LPA) is a potent bioactive lipid that profoundly influences cellular signaling and function upon binding to G protein-coupled receptors (LPA1-6). The majority of circulating LPA is produced by the secreted enzyme autotaxin (ATX). Alterations in LPA signaling, in conjunction with changes in autotaxin (ATX) expression and activity, have been implicated in metabolic and inflammatory disorders including obesity, insulin resistance, and cardiovascular disease. This review summarizes our current understanding of the sources and metabolism of LPA with focus on the influence of diet on circulating LPA. Furthermore, we explore how the ATX-LPA pathway impacts obesity and obesity-associated disorders, including impaired glucose homeostasis, insulin resistance, and cardiovascular disease.
