Role of alarmins high mobility group protein B1 in sepsis / 中华危重病急救医学

ABSTRACT

High mobility group protein B1 (HMGB1) is the most representative substance in the alarmins family, it is actively or passively release to extracellular by the activation of monocyte/macrophage and the dead cells, and then it stimulates the production of a variety of inflammatory mediators, and increases the organism's inflammatory response through relevant receptors signaling pathways. In recent years, its concentration can reflect the severity of inflammation and injury and was related to the prognosis, HMGB1 has won more and more attention in the development of sepsis. By reviewing the study of HMGB1 in sepsis pathogenesis, signal pathway and reversal measures, it was found that HMGB1 was considered as an important inflammatory mediators and warning signal involved in the pathogenesis of sepsis, and was become a new target in the treatment of sepsis. Further research on the role of HMGB1 in the pathogenesis of sepsis is needed in the future, and the development of new drugs combined with HMGB1 will be used in the study of HMGB1 in animal experiments.
