Research progress of ferroptosis related pathways in sepsis / 中华危重病急救医学

ABSTRACT

Sepsis is a disease caused by pathogenic microorganisms such as bacteria, which is characterized by host response disorder, organ dysfunction and high mortality. In early stage, it is mainly inflammatory reaction, howeverin late stage, it is mainly immunosuppression. It is a little pale to explain the poorprognosis caused by sepsis only by severe infection and immunosuppression. From the perspective of the absolute mortality of sepsis over the world, the battle against sepsis has not won a comprehensive victory. It has been 10 years since "ferroptosis" was formally proposed by Dixionet al. in 2012. The research areahas never decreased from the initial tumor related diseases to nervous system diseases and cardiovascular system diseases, and has made some progress. At present, in the context of sepsis, it is found that ferroptosis plays an increasingly important role in organ dysfunction, and also has an important impact on the treatment and prognosis of the disease. This article summarizes the related pathways and interventions of several major ferroptosis at present, in order to have a more comprehensive understanding of the pathogenesis of sepsis, seek new treatment targets, optimize diagnosis and treatment strategies, and improve survival rate, quality of life and clinical prognosis.
