【摘要】 褪黑素（melatonin, MT）是一种内源性激素，可作为安全有效的睡眠辅助剂用于调节昼夜周期。除传统功能之外，越来越多的研究表明褪黑素可以在感染性疾病的治疗中发挥重要作用。褪黑素在感染性疾病中的治疗作用机制主要涉及调控氧化应激减轻感染造成的组织损伤以及调控昼夜节律增强免疫功能两方面。此外，褪黑素还可以通过调节Th1/Th2发育及分化、NF-κB的磷酸化等方面发挥抗炎效应，并影响细胞凋亡途径等发挥一定的抗感染作用。本文概述褪黑素在感染性疾病治疗中的研究现状及上述作用机制，以期为褪黑素在临床抗感染领域的应用提供理论依据。更多还原

【Abstract】 Melatonin(MT) is an endogenous hormone that acts as a safe and effective sleep aid for regulating the circadian cycle. In addition to its traditional functions, more researches suggest that MT can play an important role in the treatment of infectious diseases. The therapeutic mechanism of MT in infectious diseases mainly involves the effect of reducing tissue damage caused by infection via regulating oxidative stress and enhancing immune function induced by regulating circadian rhythm to recruit immune cells. Moreover, MT can exert an anti-inflammatory effect by regulating Th1/Th2 development and differentiation, NF-κB phosphorylation and so on, and affect the apoptosis pathway to play a certain anti-infective effect. Based on the above functions of MT, this article summarizes the research status and mechanism of MT in the treatment of infectious diseases in order to provide a theoretical basis for the application of MT against infection in clinical settings.更多还原
