类风湿关节炎(RA)是一种病因不明的自身免疫性疾病,其发病机制既有遗传因素,也有环境因素。虽然对感染和吸烟等其他环境因素进行了广泛的研究,并显示出一些关联,但所有这些因素之间的直接联系一直很难得到证明。随着最近技术的进步,对存在于我们肠道中的共生基因进行排序已经成为可能。肠道微生物群可能提供了这一谜题缺失的一环,并帮助解开了许多肠道渗漏综合征的谜团。肠道共生体参与维持宿主免疫动态平衡和功能,这表明它们可能在改变免疫系统从而导致自身免疫性疾病(如类风湿性关节炎)方面起关键作用。小鼠模型支持肠道微生物区系在RA易感性中的作用。如果这是真的,那么可以利用肠道共生的力量,通过生成生物标记物和遗传因素来定义处于风险中的个人,并使用各种手段改变肠道微生物组成,从而使我们受益。
Rheumatoid arthritis (RA) is an autoimmune disease with unknown etiology though both genetic and environmental factors have been suggested to be involved in its pathogenesis. While infections and other environmental factors like smoking have been studies extensively and show some association, a direct link between all the factors has been difficult to prove. With the recent advances in technology, it has become possible to sequence the commensals that are residing in our gut. The gut microbiome may provide the missing link to this puzzle and help solve the mystery of many leaky gut syndromes. The gut commensals are involved in maintaining host immune homeostasis and function suggesting that they might be critical in altering the immune system that leads to autoimmune diseases like RA. Mouse models support the role of the gut microbiota in predisposition to RA. If that is true, the power of gut-derived commensal can be harnessed to our benefit by generating a biomarker profile along with genetic factors to define individuals at risk and by altering the gut microbial composition using various means.
