Ischemic reperfusion during stroke treatment increases the pathological progression of stroke. Reperfusion with r-TPA and mechanical thrombectomy applied to stroke patients increases the risk of intracerebral hemorrhage. In addition, various molecular signals initiated during ischemic reperfusion exacerbate the disease due to increased endothelial permeability. However, a detailed molecular therapeutic regimen with r-TPA and mechanical thrombectomy could limit the detrimental effects and increase the survival rate. Lysophosphatidic acid (LPA) is a bioactive phospholipid regulated in physiological and pathological conditions. LPA is produced by the enzyme autotaxin (ATX). ATX and LPA have been observed to deteriorate physiological status in various diseases such as myocardial infarction, Alzheimer's disease, liver fibrosis, neuropathic pain etc. In cerebral ischemic-reperfusion, the ATX-LPA axis could initiate the endothelium disruption.
