虽然微生物传统上被视为病原体,但现在已经明确,大多数宿主 - 细菌相互作用是共生的。在发育过程中以及进入成年期,肠道细菌塑造了我们胃肠免疫系统的组织、细胞和分子特征。这种经过数千年共同进化形成的伙伴关系,是基于一种分子交换,其中涉及被宿主受体识别的细菌信号,以介导对微生物和人类都有益的结果。在此我们探讨肠道共生细菌如何影响适应性免疫系统的特定方面。理解介导共生细菌与人类之间共生关系的分子机制,可能会重新定义我们对适应性免疫进化的看法,进而重新定义我们治疗众多免疫性疾病的方法。
Although microbes have been classically viewed as pathogens, it is now well established that the majority of host-bacterial interactions are symbiotic. During development and into adulthood, gut bacteria shape the tissues, cells and molecular profile of our gastrointestinal immune system. This partnership, forged over many millennia of co-evolution, is based on a molecular exchange involving bacterial signals that are recognized by host receptors to mediate beneficial outcomes for both microbe and man. We explore herein how specific aspects of the adaptive immune system are influenced by intestinal commensal bacteria. Understanding the molecular mechanisms which mediate symbiosis between commensal bacteria and humans may redefine how we view the evolution of adaptive immunity, and as a result, the way we approach treating numerous immunologic disorders.
