Research progress on the roles and mechanisms underlying metabolic molecules involved in nutrition therapy and immune regulation in sepsis / 中华危重病急救医学

ABSTRACT

The pathology of sepsis is extremely complex. Pathogen invasion, inflammatory factors secretion, coagulation disorder and microcirculation disturbance lead to metabolic disorder and organ dysfunction. In recent years, immunometabolism has aroused continuous attention in aspect of nutrition therapy and immune intervention for sepsis. Nutrition metabolites include amino acids, fatty acids, and glucose metabolites, which are not only the nutritional ingredients, but also the regulators of innate immune and adaptive immune. Fatty acids and glucose metabolites are involved in regulation of immune response mainly via free fatty acid receptors and AMP-activated protein kinase/mammalian target of rapamycin (AMPK/mTOR) signaling pathway. Here, we summarized the research progress on the roles of nutrition metabolites in nutrition therapy and immune regulation during sepsis, which could provide a new direction for the development of metabolic therapy for sepsis.
