摘要:

心力衰竭是各种心血管疾病发展的终末阶段,其死亡率高,预后差,是危害人类生命健康的重大疾病。心力衰竭时,交感神经系统激活,儿茶酚胺激活β受体(β-AR)通过Gs蛋白-腺苷酸环化酶-环磷酸腺苷-蛋白激酶A(Gs-AC-cAMP-PKA)信号通路增加心输出量,这在短期内有益,但持续激活β受体最终会导致心脏收缩力降低。在这一病理过程中,A型激酶锚定蛋白(AKAP)起着重要的作用,AKAP通过将PKA锚定在特定的亚细胞区域来调节信号通路。β受体阻滞剂被广泛用于心力衰竭的治疗,但也会带来一系列的副作用。因此,未来需要更加新颖且有针对性的治疗方法来改善心衰。

Abstract:

Heart failure is the final stage of the development of various cardiovascular diseases. Because of its high mortality rate and poor prognosis, it has become a major disease that endangers human life and health. In heart failure, the sympathetic system is activated and the catecholamines stimulate β-adrenergic receptor (β-AR) to increase cardiac output via Gs-AC-cAMP-PKA signaling pathway, which is beneficial in the acute phase, but chronic β-ARs stimulation eventually leads to a diminished contractile performance of the heart. A-kinase anchoring protein (AKAP) plays an important role in this pathological process, which regulates signaling pathways by anchoring PKA in specific subcellular locations. β-blockers are widely used in the treatment of heart failure, but also have a range of side effects.Therefore, novel and more targeted therapeutic treatments are needed to improve treatment of HF in the future.

Key words: kinase anchoring protein, heart failure, protein kinase A, β-adrenergic receptor
