摘要


Secretory Ig A (sIgA) plays an important role in the maintenance of intestinal homeostasis via cross-talk with gut microbiota. The defects in sIgA production could elicit dysbiosis of commensal microbiota and subsequently facilitate the development of inflammatory bowel disease. Our previous study revealed activating transcription factor 3 (ATF3) as an important regulator of follicular helper T (TFH) cells in gut. ATF3 deficiency in CD4+ T cells impaired the development of gut TFH cells, and therefore diminished sIgA production, which increased the susceptibility to murine colitis. However, the potential role of microbiota in ATF3-mediated gut homeostasis remains incompletely understood. In this study, we report that both Atf3 and CD4Atf3 mice displayed profound dysbiosis of gut microbiota when compared with their littermate controls. The proinflammatory Prevotella taxa, especially Prevotella copri, were more abundant in ATF3-deficient mice when compared with littermate controls. This phenotype was obviously abrogated by adoptive transfer of either TFH cells or IgA+ B cells. Importantly, depletion of gut microbiota dramatically alleviated the severity of colitis in Atf3 mice, whereas transfer of microbiota from Atf3 mice to wild-type recipients increased their susceptibility to colitis. Collectively, these observations indicate the importance of IgA-microbiota interaction in ATF3-mediated gut homeostasis.
