Core Tip

Core Tip: Mesenteric adipose tissue and creeping fat (CrF) may play a potential role in Crohn's disease (CD) progression, providing new insights and promising avenues for therapeutic intervention. Fecal microbiota transplantation (FMT) from healthy donors may partially mitigate intestinal inflammatory infiltration, improve intestinal permeability, enhance barrier function, and reduce systemic inflammation in patients with CD. Conversely, FMT from CD patients exacerbates inflammatory changes and contributes to intestinal wall fibrosis. In the present study, we found that the gut microbiota played a multifaceted role, mediating the properties of CrF and influencing the inflammatory and fibrotic phenotypes associated with CD.
