Intestinal microbiota controls multiple aspects of body homeostasis. The microbiota composition changes easily in response to internal or external factors, which may result in dysbiosis and associated inflammatory reactions. Thus, maintaining the microbiota composition by the host immune system is crucial, and one of the main mechanisms for microbiota control is production of immunoglobulin A (IgA) at mucosal surfaces. The molecular mechanisms regulating the interactions between the immune system and microbiota remain obscure. A panel of hybridoma cell lines was constructed to produce monoclonal IgA antibodies specific to various commensal bacteria present in intestinal microbiota. The panel can be used to further understand the mechanisms whereby the adaptive immune system controls the microbiota composition.
