Intestinal mucin secreted from goblet cells forms a mucus layer, and acts as a mucosal barrier separating intestinal epithelial cells and intestinal bacteria. Recent studies on the structure and function of mucin glycans have revealed that sulfation of O-linked glycans on intestinal mucin is important for the mucosal barrier function, which maintains intestinal homeostasis and protects against inflammatory bowel diseases.

Inflammatory Bowel Disease and Sulfated Mucin

摘要

Intestinal mucin secreted from goblet cells forms a mucus layer, and acts as a mucosal barrier separating intestinal epithelial cells and intestinal bacteria. Recent studies on the structure and function of mucin glycans have revealed that sulfation of O-linked glycans on intestinal mucin is important for the mucosal barrier function, which maintains intestinal homeostasis and protects against inflammatory bowel diseases.
