摘要
心脏纤维化参与各种心脏疾病发生发展进程,持续进展可导致心脏结构重塑和功能障碍,增加心血管疾病的死亡风险。新型的力学敏感性离子通道Piezo1可将精细的力传感器与调节Ca^(2+)内流结合起来,参与细胞的力学转导,从而调控细胞生物功能,开辟了细胞力学转导研究的新领域。近年来研究表明,心肌损伤后发生的生物力学改变,可诱导心脏细胞中Piezo1表达上调并介导钙稳态失衡,在心脏纤维化正反馈环路中扮演着重要角色。本文对Peizo1参与调控心脏纤维化的理论基础及相关研究进行综述,并对Piezo1通道有望成为抗纤维化治疗的新靶点进行讨论,以期为心脏纤维化的防治提供新的研究视野。
During the occurrence and development of various heart diseases,continuous deterioration of myocardial fibrosis leads to remodeling and dysfunction of the cardiac structure.As a newly discovered mechanically sensitive ion channel,Piezo1 has opened up a new field of research on cellular mechanical transduction.Piezo1 combines a fine force transducer with Ca~(2+ )influx and participates in the regulation of cellular mechanical transduction,thereby regulating cellular biological functions.Recent studies have shown that the biomechanical changes induced by myocardial injury regulate the expression of Piezo1 in cardiomyocytes and cause an imbalance in calcium homeostasis,which plays an important role in the positive feedback loop of myocardial fibrosis.This review summarizes the theoretical basis and related studies of Piezo1 in regulating cardiac fibrosis and suggests that the Piezo1 channel may become a new target for the treatment of cardiac fibrosis,thereby providing a new research horizon for the prevention and treatment of cardiac fibrosis.
