Interactions between the microbiota and distal gut are important for the
maintenance of a healthy intestinal barrier; dysbiosis of intestinal microbial
communities has emerged as a likely contributor to diseases that arise at the
level of the mucosa. Intraepithelial lymphocytes (IELs) are positioned within the
epithelial barrier, and in the small intestine they function to maintain
epithelial homeostasis. We hypothesized that colon IELs promote epithelial
barrier function through the expression of cytokines in response to interactions
with commensal bacteria. Profiling of bacterial 16S ribosomal RNA revealed that
candidate bacteria in the order Bacteroidales are sufficient to promote IEL
presence in the colon that in turn produce interleukin-6 (IL-6) in a MyD88
(myeloid differentiation primary response 88)-dependent manner. IEL-derived IL-6
is functionally important in the maintenance of the epithelial barrier as
IL-6(-/-) mice were noted to have increased paracellular permeability, decreased
claudin-1 expression, and a thinner mucus gel layer, all of which were reversed
by transfer of IL-6(+/+) IELs, leading to protection of mice in response to
Citrobacter rodentium infection. Therefore, we conclude that microbiota provide a
homeostatic role for epithelial barrier function through regulation of
IEL-derived IL-6.
