Oxidative phosphorylation in septic organ injury / 国际儿科学杂志

ABSTRACT

Sepsis is a systemic inflammatory response syndrome caused by pathogenic microorganisms that infect the host.If treated improperly, it can progress to severe sepsis or even septic shock.As such, it′s one of the main reasons for the death of children in PICU.The inflammatory response of sepsis exerts great influence on a series of basic physiological functions of cells, including the oxidative phosphorylation of the mitochondria.Oxidative phosphorylation is a process during which oxygen is reduced to generate high-energy phosphate bonds in the form of adenosine triphosphate(ATP), which supplies energy for cells and produces a series of functional by-products.During sepsis, the process of oxidative phosphorylation in mitochondria undergoes a series of complex alterations, which in turn can further promote the development of septic organ injury.The present review aims to clarify the relationship between changes in oxidative phosphorylation and the impairment of various organs in sepsis.
