Microbiota in autoimmunity and tolerance

Curr Opin Immunol. 2011 Dec;23(6):761-8. doi: 10.1016/j.coi.2011.11.002. Epub 2011 Nov 22.

Abstract

The composition of a host's intestinal microbiota directs the type of mucosal and systemic immune responses by affecting the proportion and number of functionally distinct T cell subsets. In particular, the microbiota composition affects the differentiation of intestinal Th17 cells and Foxp3(+) regulatory T cells, both of which play critical roles in maintaining mucosal barrier functions and in controlling immunological homeostasis. In this review, we discuss the recent advances in our understanding of how the intestinal microbiota affects T cell differentiation and host susceptibility to autoimmune disease.
