Experimental colitis is an area of research that involves inducing inflammation in the colon of laboratory animals in order to study the mechanisms of inflammatory bowel diseases such as Crohn's disease and ulcerative colitis. This model allows researchers to investigate the pathophysiology of colitis, test potential therapies, and identify biomarkers for diagnosis and monitoring of the disease. Various methods can be used to induce colitis in animals, such as chemical induction, genetic manipulation, or immune system activation. This research is crucial for understanding the complex mechanisms underlying colitis and developing effective treatments for patients with these debilitating conditions.
