Obesity:心脏蛋白、肥胖症及糖尿病之间的神秘关联

2016-02-19 佚名 生物谷

近日,一项刊登于国际杂志Obesity上的研究论文中,来自Sanford Burnham Prebys医学研究所的研究人员揭示了心脏分泌产生的蛋白质同肥胖、葡萄糖耐受不良及胰岛素耐受性之间的重要关联,该研究为开发利用靶向作用控制血液中特殊蛋白浓度的新方法,从而治疗机体代谢性障碍,包括2型糖尿病等疾病提供了新的思路。 研究者Sheila Collins博士说道,我们的研究结果揭示了心脏利尿钠肽(N

近日,一项刊登于国际杂志Obesity上的研究论文中,来自Sanford Burnham Prebys医学研究所的研究人员揭示了心脏分泌产生的蛋白质同肥胖、葡萄糖耐受不良及胰岛素耐受性之间的重要关联,该研究为开发利用靶向作用控制血液中特殊蛋白浓度的新方法,从而治疗机体代谢性障碍,包括2型糖糖尿病等疾病提供了新的思路。

研究者Sheila Collins博士说道,我们的研究结果揭示了心脏利尿钠肽(NPs)的调节在肥胖、胰岛素耐受性及2型糖尿病患者机体中如何改变;当研究者检测这些代谢性障碍患者机体的脂肪组织时,他们发现在患者机体循环中清除NPs的受体水平较高,这就说明,如果可以增强NP的水平或者减少其清除受体的水平,那么或许就可以帮助纠正患者的机体障碍。

心脏利尿钠肽(NPs)是心脏产生的一种激素,其主要被认为可以调节血压;当心脏感知血压升高后,其就会释放NPs,产生的NPs会进入肾脏诱发机体从血液中释放盐分和水份从而降低血压。NPs可以通过活性受体(NPRA)传输信号来促进机体对血压的反应,同时其还可以通过清除受体(NPRC)从血液中移除,这两种受体都会促成NP表现出活性水平。

大约20年前,研究人员就在人类脂肪组织中意外发现了NP受体,NP受体的水平在机体代谢和肥胖中扮演着重要角色,的确随后的研究也发现在肥胖及其它代谢障碍患者的机体中NP受体的水平较低,最近研究者们才发现,肥胖个体的脂肪组织中存在高水平的清除作用受体。

研究者Richard Pratley指出,我们在多个体重指数及胰岛素敏感性患者机体的脂肪组织和骨骼组织中都检测出了NPRA和NPRC的存在,而且较高的体重指数和脂肪组织中清除作用受体的水平升高直接相关。同时研究者还在摄入药物吡格列酮后的2型糖尿病患者机体中发现了NP受体的存在,吡格列酮可以帮助改善机体的胰岛素敏感性并且控制2型糖尿病集体的血糖;更有意思的是研究者还发现,这些患者的脂肪组织中清除受体的水平明显下降了,这就进一步强调了NPs、胰岛素耐受性及肥胖之间的重要关联了。

本文研究发现,靶向作用增加NP水平通路的特殊药物或可帮助科学家开发新型方法来有效治疗一系列机体代谢性障碍,比如肥胖症、胰岛素耐受性、潜在的2型糖尿病。如今研究者已经获得了被FDA批准的用于控制血糖的药物,而且他们也知道这些药物可以影响NP的水平,为此研究者希望可以对这些药物重新设计来特殊地靶向作用其它包括肥胖在内的代谢性障碍
