MUC17 is an essential small intestinal glycocalyx component that is disrupted in Crohn’s disease

Abstract excerpt

Crohn's disease (CD) is the chronic inflammation of the terminal ileum and colon triggered by a dysregulated immune response to bacteria, but insights into specific molecular perturbations at the critical bacteria-epithelium interface are limited. Here, we report that the membrane mucin MUC17 protected small intestinal enterocytes against commensal and pathogenic bacteria. In noninflamed CD ileum, reduced MUC17...
