近日,一篇发表在国际杂志Cell Host & Microbe上的研究论文中,来自康奈尔大学的研究人员通过对英国1000多对双胞胎进行全基因组关联性研究发现,机体一部分微生物组是可以通过遗传和塑形的,而这并不是通过微生物从父母向儿童进行扩散,而是通过我们自身的基因来实现的,相关研究结果揭示了一种新型的遗传性细菌群落,其或许和个体的饮食喜好、代谢和机体免疫力直接相关。

研究者Ruth Ley说道,我们开始着手去寻找参与调节机体肠道微生物组的人类基因,最终我们发现了一些线索,我们发现的一些关联性就位于LCT基因和双歧杆菌中,LCT基因主要参与制造特殊酶类来帮助机体消化乳制品,而双歧杆菌则常用作有益菌种;同时研究者还发现特殊的肠道细菌血压和自我/非自我识别存在一定关联。

基于当前研究结果,研究人员鉴别出了和可遗传健康相关连的十多个微生物,这些微生物均可以从环境中获得,但其基因组却发挥着特殊的功能,可以帮助确定哪些微生物更占主导优势。文章中研究人员分析了来自TwinsUK 研究计划中1126对双胞胎机体中的肠道微生物组,TwinsUK研究是一项对同卵和异卵双胞胎进行的大型研究,其中包括对12000对双胞胎进行研究来寻找多种疾病及机体症状。

当前研究中,研究人员对双胞胎进行了基因组分析,其中有130万个小型的遗传变异(单核苷酸多态性)对每位参与者都是众所周知的,随后研究者利用全基因组关联性方法来寻找双胞胎间遗传变异和其机体中特定细菌类型之间的关联。研究者Ley指出,本文研究对象的总数对于进行全基因组关联性研究分析而言仍然很小,但其却可以帮助我们证实此前在一些小型研究中的结果,本文研究证实了此前的研究结论,即一些类型的细菌是可以进行遗传的,但和双胞胎间差异相关的特殊基因却并没有发现;本文研究为揭示双胞胎间特殊的遗传基因和肠道微生物组的差异以及二者的关联提供了新的研究线索和思路。
