成年哺乳动物的下肠密集地定植有非致病性(肠道)微生物。肠道细菌诱导保护性免疫反应,确保宿主-微生物互利共生。肠道细菌的持续存在使得研究粘膜免疫动力学变得困难。在这里,我们报告了一个可逆的无菌定植系统在小鼠中,是独立的饮食或抗生素操作。在无菌小鼠中观察到缓慢(> 14天)的长寿命(t1/2> 16周)、高度特异性抗IgA应答。在定殖小鼠中持续的水杨酸暴露迅速消除了这种反应。连续剂量缺乏在全身接种中观察到的经典的初免-加强效应,但是特异性IgA诱导作为对当前细菌暴露的逐步响应而发生,使得抗体库与现有的疫苗内容物相匹配。
The lower intestine of adult mammals is densely colonized with non-pathogenic (commensal) microbes. Gut bacteria induce protective immune responses, which ensure host-microbial mutualism. The continuous presence of commensal intestinal bacteria has made it difficult to study mucosal immune dynamics. Here we report a reversible germ-free colonization system in mice that is independent of diet or antibiotic manipulation. A slow (>14 days) onset of a long-lived (t1/2>16 weeks), highly specific anti-commensal IgA response in germ-free mice was observed. Ongoing commensal exposure in colonized mice rapidly abrogated this response. Sequential doses lacked a classical prime-boost effect seen in systemic vaccination, but specific IgA induction occurred as a stepwise response to current bacterial exposure, such that the antibody repertoire matched the existing commensal content.
