Distinguishing between commensal and pathogenic bacteria to generate appropriate responses (tolerance vs. immunogenicity) is a key decision that the human immune system must make to maintain homeostasis. Recently, Clasen and colleagues reported a distinct allosteric interaction between bacterial flagellin and host Toll-like receptor 5 (TLR5), which may shed light on these differences.
区分共生菌和病原菌以产生适当反应(耐受与免疫原性)是人类免疫系统为维持体内平衡必须做出的关键决定。最近,克拉森及其同事报道了细菌鞭毛蛋白与宿主 Toll 样受体 5(TLR5)之间一种独特的变构相互作用,这可能有助于阐明这些差异。
