Outline of Final Research Achievements

1. Myosin di-phosphorylation and peripheral actin bundle formation as initial events during endothelial barrier disruption. 2. The Rho-Rho kinase pathway plays an important role in the peripheral localization of ppMLC and actin filament formation during the initial phase of the thrombin-induced endothelial barrier disruption. 3. The coagulation factor XIa induces Ca2+ signal via proteinase-activated receptor 1(PAR1) and L-type Ca2+channel in vascular smooth muscle cells. 4. Specific and increased expression of thrombin receptor PAR1 in pulmonary artery plays a key role in the pathogenesis of monocrotaline-induced pulmonary hypertension in rats.
