Abstract
Pulmonary vascular remodeling contributes to the development of pulmonary vascular resistance in patients with pulmonary hypertension (PH). The development of PH involves a multiple genetic, molecular, and humoral abnormalities, in which fibroblasts, vascular smooth muscle and endothelial cells, and inflammatory cells play a crucial role. A series of studies demonstrated the important roles of Rho-kinase in the cardiovascular system. The RhoA/Rho-kinase pathway plays important roles in many cellular functions, including contraction, motility, proliferation, and apoptosis, and its excessive activity induces oxidative stress. Furthermore, the important role of Rho-kinase has been demonstrated in the pathogenesis of many cardiovascular diseases including PH. Additionally, cyclophilin A is secreted by vascular smooth muscle cells, inflammatory cells, and activated platelets in a Rho-kinase-dependent manner, playing important roles in a wide range of cardiovascular diseases. Therefore, the RhoA/Rho-kinase pathway plays crucial roles in both physiological and pathological conditions and is an important therapeutic target in cardiovascular medicine. Here, we will review the recent advances regarding the importance of Rho-kinases in the development of PH and as a therapeutic target.
