Advances in research on signal transduction mechanisms and their inhibitors for the proliferation of pulmonary artery smooth muscle cells / 中国药理学通报

Pulmonary artery hypertension (PAH ) is a chronic progressive disease characterized by a persistent elevation of pul-monary vascular pressure,and the disease would limit the right ventricular function severely,fail the organ and even lead to death in the end.The histopathological change of PAH is fea-tured by the restructuring of pulmonary vessels,and the abnor-mal reproduction of pulmonary artery smooth muscle cells (PASMCs)in peripheral vessels is the major pathological basis of pulmonary vascular restructuring.This paper mainly reviews the research advances on signal transduction mechanisms and their inhibitors in promoting the proliferation of pulmonary artery smooth muscle cells.
