HMGB1: key mediator in digestive system diseases.

High Mobility Group Box 1 (HMGB1), a multifunctional non-histone protein, and its involvement in various physiological and pathological contexts has garnered significant attention. Given HMGB1's central function in modulating key biological activities, such as inflammatory responses and cellular death, its contribution to the pathogenesis of digestive system diseases has become a focus of growing interest. This review aims to comprehensively explore the mechanisms by which HMGB1 contributes to the progression of inflammatory bowel disease (IBD), liver disorders, and pancreatitis. Furthermore, we explore the prospective clinical applications and outline future research directions for HMGB1 in digestive diseases, providing fresh perspectives that highlight the necessity of ongoing studies to understand its role in these conditions.
