Intestinal epithelial cells as mediators of the commensal–host immune crosstalk

Abstract excerpt

Commensal bacteria regulate the homeostasis of host effector immune cell subsets. The mechanisms involved in this commensal-host crosstalk are not well understood. Intestinal epithelial cells (IECs) not only create a physical barrier between the commensals and immune cells in host tissues, but also facilitate interactions between them. Perturbations of epithelial homeostasis or function lead to the development of...
