研究人员成功逆转马凡氏小鼠心脏衰竭】约翰斯·霍普金斯大学的研究人员在对老鼠的实验中发现,在老鼠身上有一种啮齿类动物的“马凡氏综合症”,即使在正常的老鼠体内,它们的心脏承受的压力也会稍微增加,这也会导致心脏衰竭。

发表在《临床调查透视》杂志上的研究结果显示,心脏组织中有一种新的细胞通路,导致心脏衰竭,并可能成为治疗马凡氏综合症的标准疗法。马凡氏综合症是一种遗传性疾病,它会影响整个身体的结缔组织,例如伸展四肢、手指和脚趾。然而,它最坏的影响是在心脏的血管和瓣膜。主动脉肿大、心脏瓣膜渗漏和心脏功能衰弱,心脏增大和泵抽力减弱都可能危及生命。

霍普金斯大学的研究小组的科学人员表示:“有一小部分儿童患有马凡氏症候群,他们表现出明显的心力衰竭症状,而且只有少量的瓣膜渗漏。”

在此次试验过程中,研究人员观察了小鼠五周内心脏的变化,通过使用超声心动图,研究人员观察到,马凡氏小鼠的心脏大小显着增加,平均体重为200毫克,与对照组小鼠相比,平均体重为75毫克,这是小鼠和人类心脏衰竭的一种表现。

研究人员随后研究了马凡氏小鼠心脏组织中诱发心脏衰竭的机制,他们发现心脏的肌肉细胞正在变得更大,因为他们接收到来自邻近纤维细胞异常生长的化学信号,这些细胞组成了心脏的结构骨架。

通过追踪细胞内的信号,研究人员发现,其中一种受影响的途径是一种叫做转化生长因子贝塔的蛋白质,这种蛋白质在马凡综合症患者中增加,而且是许多症状的来源。利用这些知识,研究小组重复了他们的实验,但这次引入了抑制生长因子信号通路的药物疗法。具体地说,他们给老鼠洛沙坦(losartan),一种目前在治疗高血压的药物,以及refametinib,一种用于癌症临床试验的实验性药物,试验显示,所有的马凡氏小鼠都能逆转心脏衰竭。
