肠道内有大量的肠道细菌,经常受到食源性病原体和毒素的攻击。适当调节的免疫应答对于维持肠道的稳态以及保护肠道免受感染和毒素的侵害至关重要。伊加同种型抗体在粘膜部位如肠中特异性地起作用,以通过结合并调节肠道微生物群、病原体和毒素来帮助维持肠道健康。伊加抗体由肠道伊加抗体分泌浆细胞产生,该浆细胞在肠道相关淋巴组织中由幼稚B细胞响应肠道细菌和组分的刺激而产生。研究IgA分泌细胞的产生、迁移和维持对于我们理解伊加反应的生物学和帮助更好地设计针对肠道感染的疫苗非常重要。
The intestine harbors enormous numbers of commensal bacteria and is under frequent attack from food-borne pathogens and toxins. A properly regulated immune response is critical for homeostatic maintenance of commensals and for protection against infection and toxins in the intestine. IgA isotype antibodies function specifically in mucosal sites such as the intestines to help maintain intestinal health by binding to and regulating commensal microbiota, pathogens and toxins. IgA antibodies are produced by intestinal IgA antibody-secreting plasma cells generated in gut-associated lymphoid tissues from naïve B cells in response to stimulations of the intestinal bacteria and components. Research on generation, migration, and maintenance of IgA-secreting cells is important in our effort to understand the biology of IgA responses and to help better design vaccines against intestinal infections.
