Intestinal inflammation

“Intestinal inflammation” refers broadly to an immune-mediated pathological state characterized by infiltration of immune cells into the gut mucosa, increased production of pro-inflammatory cytokines such as TNFα and IL‑6, disruption of epithelial barrier integrity, altered microbiota composition, and tissue damage. This process underlies diseases like Crohn’s disease and ulcerative colitis—collectively known as inflammatory bowel diseases—and can lead to complications such as fibrosis or cancer if chronic. While many drugs aim to reduce intestinal inflammation by targeting specific molecules within this cascade—such as TNFα or IL‑6—the term itself does *not* denote any single molecular entity but rather encompasses multiple interacting cellular processes and mediators[1][2][4][6].

Mechanisms are directed at suppressing immune cell activation and cytokine production, including cytokine inhibition (anti-TNFα, anti–IL‑6), immune cell modulation, and JAK/STAT pathway inhibition.
