GUT: 粪便病毒移植可减轻鼠模型中2型糖尿病和肥胖的症状

2020-11-08 MedSci原创 MedSci原创

肥胖和2型糖尿病(T2D)的发展与肠道菌群(GM)的变化有关。肠道病毒群落以噬菌体(噬菌体)为主,噬菌体是以宿主特异性方式攻击细菌的病毒。

背景及目的

肥胖和2型糖尿病(T2D)的发展与肠道菌群(GM)的变化有关。肠道病毒群落以噬菌体(噬菌体)为主,噬菌体是以宿主特异性方式攻击细菌的病毒。为了证明噬菌体的行为具有改变GM的潜力。本项研究旨在探究自瘦供体的粪便病毒移植(FVT)是否可以将肥胖小鼠的表型转变为与瘦小鼠更相似的功效。

 

方法:

FVT由具有不同特征的病毒组成,这些病毒是从不同供应商的小鼠的盲肠中提取的,这些小鼠接受了低脂(LF)饮食喂养14周。将雄性C57BL / 6NTac小鼠分为五组:LF(作为饮食控制),高脂(HF)饮食,HF +氨苄青霉素(Amp),以及HF + Amp + FVT组和HF + FVT组。在研究的第6周和第7周,通过口管饲喂FVT治疗HF + FVT和HF + Amp + FVT小鼠。

 

 

结果

结果显示首次进行FVT治疗六周后,与HF组相比,HF + FVT小鼠的体重增加显着减少。此外,LF和HF + FVT小鼠之间的葡萄糖耐量相当,而其他HF组的葡萄糖耐量均受损。GM组成,血浆代谢组以及与肥胖和T2D发育相关的基因的表达水平发生了显着变化,为这些观察提供了支持。

 

结论

与瘦小鼠相比,将盲肠病毒群落从具有瘦表型的小鼠转移至具有肥胖表型的小鼠可导致体重增加减少和血糖参数正常化。这种作用证实是通过FVT诱导的GM变化介导的。
