Abstract:
Sepsis, a series of pathophysiological abnormalities caused by infection, is also one of the most important factors of death and disability in infected patients all over the world, so it has always been the focus of the medical community. Cytokines are small molecule proteins secreted by cells with biological activity, involved in the immune and inflammatory regulation of sepsis. Many studies using cytokine targeting to treat sepsis have achieved beneficial effects, and the level of cytokines is also believed to be related to the development, severity of sepsis, so they are reliable biomarkers of sepsis. Among them, pro-inflammatory cytokines such as interferon-β (IFN-β) and interleukins (IL-1β, IL-3, IL-6, and IL-7) are the focus of the discussion in this review. IFN-β and IL-1β are double-sided in the treatment of sepsis, namely early low-dose treatment can reduce sepsis by restoring the function of immune cells and play a protective effect, but they are also related to severe inflammatory response of sepsis and can aggravate the mortality of sepsis patients. IL-3 and IL-6 focus more on enhancing inflammatory factors and play a damage role. IL-7 mainly participates in immune regulation, promoting lymphocyte activation and protecting sepsis.
