Abstract:

Neutrophils,which have become the largest number of immune cells in the peripheral blood,are the important components of the innate immune system in the body and which constitute the first line of defensing against microbial invasion, playing an important role in nonspecific immunity. Besides of the classic phagocytosis of pathogens, degranulation and the release of bactericidal substances, it is found that neutrophils have a new mechanism——Neutrophil extracellular traps (NETs), which could resist the microbial invasion in recent years. Because of the reactive oxygen,peptidylated arginine deaminase 4 and other factors, neutrophils is formed of traps with DNA as the skeleton of the network structure and containing a variety of proteases. NETs can capture and kill pathogens nonspecifically and also play a synergistic role in the production and deterioration of certain diseases. This article is an overview on the formation of NETs,influencing factors and the relationship between NETs and pathogens or diseases to provide the references for studying the function of neutrophils.

Key words: polymorphonuclear neutrophil; neutrophil extracellular traps (NETs); reactive oxygen; disease
