保留射血分数(HFpEF)的心力衰竭约占所有心力衰竭病例的一半,目前尚无有效的药物治疗方法。HFpEF患者被动心肌僵硬度升高的原因是细胞外基质(ECM)胶原含量的改变和肌合成蛋白titin的改变。在这里,我们提出聚层粘连蛋白,一种仿生聚合物的层粘连蛋白,作为一种有希望的方法来操纵肌细胞中的titin异构体转移和磷酸化。探索聚层粘连蛋白的多效性可能是缓解HFpEF多因子病理生理症状的新策略。
No effective medical treatment exists for heart failure with preserved ejection fraction (HFpEF), accounting for approximately half of all heart failure cases. The elevated passive myocardial stiffness in HFpEF is attributed to a combination of alterations in the extracellular matrix (ECM) collagen content and modifications in the sarcomeric protein titin. Here, we propose polylaminin, a biomimetic polymer of laminin, as a promising approach for manipulating the titin isoform shift and phosphorylation in cardiomyocytes. Exploring the pleiotropic effects of polylaminin may be a novel strategy for alleviating symptoms in HFpEF’s multifactorial pathophysiology.
