Proinflammatory Cytokines Induce Neurotrophic Factor Expression in Enteric Glia

Abstract

A mucosal GFAP expressing EGC population is dramatically increased in CD. This population is a major cellular source of the upregulated GDNF in the inflamed gut. Therefore, mucosal EGC may play a key role in protecting the gut epithelium and may contribute to reestablish the integrity of the injured epithelium.
