| Research Abstract |
The present study elucidated the role of proteinase-activated receptors(PARs) in the early phase of the development of atherosclerotic vascular lesions. Thrombin increased endothelial permeability by two distinct pathways by activating PAR1 ; one is mediated by Gα13, and independent of Ca^<2+>, but dependent of Rho kinase-mediated MLC di-phosphorylation ; other is mediated by Gαq, and independent of MLC di-phosphorylation, but dependent on Ca^<2+>.
