Visualization of ex vivo Neutrophil Extracellular Traps by Fluorescence Microscopy
荧光显微镜法显示体外中性粒细胞胞外杀菌网
Neutrophil extracellular traps (NETs) are extracellular DNAs decorated with nuclear and granular proteins such as histones, neutrophil elastase or myeloperoxidase. They exhibit fibrous mesh-like, web-like, or string-like structures. Here, we describe our protocol regarding visualization of ex vivo NETs released from neutrophils activated by lipopolysaccharide (LPS) using fluorescence microscopy.
Quantification of ex vivo Neutrophil Extracellular Traps
通过DNA对体外中性粒细胞的胞外杀菌网进行量化
Neutrophil extracellular traps (NETs) are fibrous mesh-like, web-like, or string-like structures which are composed of DNA, histones, and granule proteins such as neutrophil elastase or myeloperoxidase. When activated by phorbol myristate acetate, interleukin-8, lipopolysaccharide (LPS), and various pathogens, neutrophils release NETs. We reported that NETs were classified as two distinct forms; cell-free NETs that were released away from neutrophils and anchored NETs that were anchored to neutrophils. In general, extracellular DNAs are used as a surrogate marker of NETs. Here, we describe a protocol regarding quantitative procedures of extracellular DNAs released from ex vivo neutrophils activated by LPS using fluorometric double-stranded DNA (dsDNA) quantification assay.
