Abstract:
In this issue of JEM, Nakajima et al. (https://doi.org/10.1084/jem.20180427) demonstrate that glycan-dependent, epitope-independent IgA coating of intestinal bacteria alters bacterial gene expression and metabolism. This conferred coated bacteria with fitness within the mucus niche and contributed to intestinal homeostasis through cross-phylum interactions.
