Science:Akkermansia muciniphila益生菌可促进肿瘤PD-1治疗效果。

2017-11-03 心湖,Juka 转化医学网

来自法国的研究团队对249名患有肺癌、肾癌等癌症的患者进行了研究。在这接受研究的患者中,有60名患者因为各种感染或者常规治疗接受了抗生素治疗。理论上来说,抗生素会扰乱肠道菌群的分布。如果肠道菌群可以影响患者的免疫治疗的话,那么这60名患者和其他的癌症患者在接受免疫治疗的时候,会出现不同的治疗效果。

而事实确实如此!研究学者经过观察发现:在接受抗生素治疗的患者群体中,患者癌症复发的概率更好,并且接受治疗后存活时间也更短!

患者疗效比较





研究人员在研究过程中发现了对免疫反应有较好作用的患者,其中肠道菌群的不同:



而在这这个研究过程中,研究人员发现了一种关键的益生菌:Akkermansia muciniphila,存在这种益生菌的患者可以更好的接受免疫治疗。

而为了验证这种联系是否是直接相关的,研究人员做了另外的两个实验:

1、将良好免疫反应患者的粪便移植到无菌小鼠体内,发现免疫效果高于那些那些没有移植的小鼠。

2、无菌小鼠在口服Akkermansia muciniphila益生菌之后,免疫反应得到回复!这证明了Akkermansia muciniphila在免疫反应中的作用!



这个研究表明:肠道菌群在免疫治疗中也占据了一席之地,至少在研究中的肺癌和肾癌患者中,肠道菌群可以很好的表现出自己的作用,并且可以促进免疫治疗的效果。
