Alarmins known as danger associated molecular patterns(DAMPs) are released into the extracellular endogenous bi-ological mediate by white blood cells and epithelial cells when body in a state of tissue injury and inflammation or physiological stress. Immunological and adaptive immune responses are activated and strengthened by chemotaxis and activation of antigen presenting cells(APC). They are closely associated with the disease development and outcome,and have important guiding significance for clinical diagnosis and treatment.%警报素(Alarmins)是机体处于组织损伤和炎症反应状态或生理应激时,由白细胞和上皮细胞等释放到胞外的内源性生物介质,也称为危险相关分子模式(Danger-associated molecular patterns,DAMPs).通过趋化和激活抗原递呈细胞( Antigen presenting cells,APC)等免疫细胞从而增强固有免疫和适应性免疫应答.它与疾病的产生发展及转归密切相关,对于临床诊疗具有重要的指导意义.
