To further explore the signaling mechanism involved in the regulatory role of PKC in thrombin-induced platelet aggregation in CD patients, we assessed the phosphorylation of PKC on Tyr SP 311 sp and Thr SP 505 sp . In human platelets, pre-treatment with the specific PKC inhibitor significantly decreased platelet activation in patients with CD. The pathogenesis of inflammatory bowel diseases (IBD), representing chronic and relapsing-remitting disorders of the gastrointestinal tract, encompasses Crohn's disease (CD) and ulcerative colitis.

Inflammatory bowel disease (IBD) is a group of chronic disorders that includes two main disease forms, Crohn's disease, and ulcerative colitis. The understanding of the intestinal inflammation occurring in IBD has been immeasurably advanced by the development of the now numerous murine models of intestinal inflammation. The usefulness of this research tool in IBD arises from a convergence of underlying genetic susceptibility, immune system dysfunction, environmental factors, and shifts in gut microbiota. Due to the multifactorial feature of these diseases, different animal models have been used to investigate the underlying mechanisms and develop potential therapeutic strategies. The results of preclinical efficacy studies often inform the progression of therapeutic strategies. This review describes the distinct feature and limitations of each murine IBD model and discusses the previous and current lessons from the IBD models. [ABSTRACT FROM AUTHOR]
