对微生物群的破坏可能会产生病理后果,这突出了了解有助于其稳定性的因素的必要性。尽管几十年的研究都集中在伊加在病原体感染过程中的重要性上,但肠道中产生的大部分伊加都靶向常驻肠道微生物。尽管有这种观察结果,但抗体在调节微生物群组成中的作用仍然存在争议,并且知之甚少。在这里,我们提出,响应于肠道微生物定植而产生的抗体通过我们称之为抗体介导的免疫选择(AMIS)的过程来塑造微生物群的组成,以有益于宿主的健康。鉴于抗体的特异性和对免疫疗法的使用的新兴趣,我们建议理解微生物群的AMIS将突出抗体操纵微生物群落以获得治疗益处的新用途。
Disruptions to the microbiota can have pathological consequences, which highlights the need to understand the factors that contribute to its stability. Although decades of research have focused on the importance of IgA during pathogenic infection, much of the IgA that is generated in the gut targets the resident commensal microorganisms. Despite this observation, the role of antibodies in regulating microbiota composition remains controversial and poorly understood. Here we propose that antibodies generated in response to microbial colonization of the gut shape the composition of the microbiota to benefit the health of the host through a process that we term antibody-mediated immunoselection (AMIS). Given the exquisite specificity of antibodies and an emerging interest in the use of immunotherapies, we suggest that understanding AMIS of the microbiota will highlight novel uses of antibodies to manipulate microbial communities for therapeutic benefit.
