溶血磷脂酸是一种小的细胞外信号分子,在缺血性卒中和创伤性脑损伤(TBI)等病理条件下升高。LPA调节各种疾病中神经元的存活。然而,lpa诱导神经元死亡的分子机制尚不清楚。本研究报道LPA激活LPA1和LPA2受体,以及下游MAPK通路,通过线粒体功能障碍诱导PC12细胞凋亡。LPA可激活ERK1/2、p38和JNK通路,降低Bcl2表达,促进Bax易位,增强caspase-3的激活,导致线粒体功能障碍和细胞凋亡。该过程可被LPA1受体拮抗剂、LPA2受体拮抗剂和MAPK通路抑制剂阻断。我们的研究结果表明LPA1受体、LPA2受体和MAPK通路在lpa诱导的神经元损伤中起关键作用。LPA受体和MAPK通路可能是缺血性卒中和TBI的新治疗靶点,其中存在过量的LPA信号。
Lysophosphatidic acid is a small extracellular signaling molecule, which is elevated in pathological conditions such as ischemic stroke and traumatic brain injury (TBI). LPA regulates the survival of neurons in various diseases. However, the molecular mechanisms underlying LPA-induced neuronal death remain unclear. Here we report that LPA activates LPA1 and LPA2 receptors, and the downstream MAPK pathway to induce the apoptosis of PC12 cells through mitochondrial dysfunction. LPA elicits the activation of ERK1/2, p38, and JNK pathways, decreases the expression of Bcl2, promotes the translocation of Bax, and enhances the activation of caspase-3, resulting in mitochondrial dysfunction and cell apoptosis. This process can be blocked by LPA1 receptor antagonist and LPA2 receptor antagonist and MAPK pathway inhibitors. Our results indicate that LPA1 receptor, LPA2 receptor and MAPK pathway play a critical role in LPA-induced neuronal injury. LPA receptors and MAPK pathways may be novel therapeutic targets for ischemic stroke and TBI, where excessive LPA signaling exist.
