对炎症性肠病(IBD)的遗传学研究增加了我们对溃疡性结肠炎(UC)和克罗恩病(CD)所涉及的途径的了解,并将注意力集中在微生物群在这些疾病中的作用上。充分了解发病机制需要全面掌握肠道细菌和人类宿主之间微妙的动态平衡。在这篇综述中,我们提出了在其他已知风险因素和机制的背景下微生物组-基因相互作用的现有证据,并描述了配对来自患者队列的遗传变异和微生物组测序数据所需的下一步步骤。我们讨论了失调的概念,提出肠道微生物组的功能组成可能提供一个更一致的定义,并可能更容易在未来的探索性研究中提供基因组-微生物组相互作用的证据。
Studies of the genetics underlying inflammatory bowel diseases (IBD) have increased our understanding of the pathways involved in both ulcerative colitis (UC) and Crohn’s disease (CD) and focused attention on the role of the microbiome in these diseases. Full understanding of pathogenesis will require a comprehensive grasp of the delicate homeostasis between gut bacteria and the human host. In this review we present current evidence of microbiome-gene interactions in the context of other known risk factors and mechanisms, and describe the next steps necessary to pair genetic variant and microbiome sequencing data from patient cohorts. We discuss the concept of dysbiosis, proposing that the functional composition of the gut microbiome may provide a more consistent definition of dysbiosis and may more readily provide evidence of genome-microbiome interactions in future exploratory studies.
