肺动脉平滑肌细胞增殖的分子信号机制研究进展

摘要

肺动脉高压是一种常见的临床综合征，以肺动脉压力升高为特征，其病理机制主要包括肺动脉血管收缩、原位血栓形成及肺血管重塑。肺动脉平滑肌细胞是构成肺动脉血管重塑的主要病理基础。因此，探讨肺动脉平滑肌细胞增殖的分子机制并进行相关干预研究，是治疗肺动脉高压的关键策略。本文综述了与肺动脉平滑肌细胞增殖有关的主要分子信号通路。%Pulmonary hypertension (PAH) is a common clinical syndrome characterized by elevated pulmonary arterial pressure. The pathological changes in PAH include increased vasoconstrictor tone, thrombosis in situ and pulmonary vascular remodeling. Pulmonary arterial smooth muscle cell (PASMC) proliferation is a hallmark of pulmonary vascular remodeling, and exploration of the molecular mechanisms of PASMC proliferation and intervention of the involved signaling pathways is therefore of great importance for prevention and treatment of PAH. This review focus primarily on the current understanding of the molecular mechanisms involved in the proliferation of PASMCs.
