Rebecca Rogier The role of intestinal microbiota in T cell-mediated experimental arthritis. Lessons from the mouse gut

We show that there is a shift in the composition of the intestinal microbiome in arthritic mice. In addition, we show that this shift already take place in the preclinical phase of arthritis, before any sings of joint inflammation are detectable. The change in the microbiome was accompanied with activation of the intestinal immune system. Moreover, we show that treating mice with an antibiotic cocktail results in a strong suppression of arthritis. Interestingly, we observed a strong correlation between the amount of Th17 cells in the intestine and arthritis severity. This supports the idea that there is a link between intestinal microbiome-induced Th17 cells and autoimmune arthritis. Our results suggest that the modulation of the intestinal microbiome or suppression of Th17-inducing bacteria may offer novel therapeutic strategies for rheumatoid arthritis.
