为了研究NETs在心脏重构中的作用,在LAD小鼠模型中使用NEi抑制NETosis,免疫荧光图像显示NEi处理可使NETs阳性面积减少3倍(图A);使用DNase I降解NETs,结果也显示NETs阳性面积小于对照组(图E)
Chromatin swelling drives neutrophil extracellular trap release
2018年9月14日 · During NETosis, neutrophils undergo dynamic and dramatic alterations of their cellular as well as sub-cellular morphology whose biophysical basis is poorly understood. Here we investigate...
2025国自然热点 | 中性粒细胞胞外诱捕网(NETs)该如何研究
胞外诱捕网 (extracellular traps,ETs) 是一种由嗜酸性粒细胞、肥大细胞和单核细胞/巨噬细胞在各种刺激作用下释放到胞外的一种网状结构,是一种以自身DNA和多种颗粒蛋白组成的纤维状结构。 该结构可捕获细菌、真菌、病毒和原虫等病原微生物以限制其在体内扩散,并通过高浓度毒性蛋白将其杀伤,是一种先天性免疫胞外防御机制。 中性粒细胞胞外诱捕网(neutrophil extracellular traps, NETs) 是其中研究最多也是最热的一个方向。 已有研究表明,NETs通常发挥抗菌作用,但过 …
中性粒细胞胞外陷阱(NETs)的精准检测新方法 - 知乎
人体免疫系统中中性粒细胞扮演着至关重要的角色。下文中开发了一种7标记物的流式细胞术方案识别外周血中性粒细胞的NETosis(中性粒细胞胞外陷阱的形成),用于分析外周血中性粒细胞的NETosis,能够区分NETotic细胞…
Methods for the Assessment of NET Formation: From Neutrophil …
Both transmission electron microscopy (TEM) and scanning electron microscopy (SEM) methods are based on an electron beam, either passing through or reflecting from the surface of the sample. In TEM, the electron beam passes through the sample and is projected onto a fluorescent screen, producing an image [ 70 ].
研究中性粒细胞胞外诱捕网(NETs)要检测哪些指标?一文带你快 …
NETosis 是中性粒细胞形成NETs的途径,包括自杀式NETosis(suicidal NETosis) 和生命 NETosis(vital NETosis)。 Suicidal NETosis状态意味着中性粒细胞的细胞死亡,而vital NETosis则保留了活的中性粒细胞功能。 NETs 的过度形成,尤其是suicidal NETosis 衍生的 NETs,会对宿主造成伤害。 作为国自然热点,NETosis 标志物的发现和评估方法对于研究NETs来说是必须要了解的。 今天,我们就通过一篇综述的解读来给大家总结下相关的内容:
How Neutrophil Extracellular Traps Become Visible - PMC
Neutrophil extracellular traps (NETs) have been identified as a fundamental innate immune defense mechanism against different pathogens. NETs are characterized as released nuclear DNA associated with histones and granule proteins, which form an extracellular web-like structure that is able to entrap and occasionally kill certain microbes.
中性粒细胞胞外陷阱(NETs)的流式检测方案 - 哔哩哔哩
2024年11月11日 · 下文中开发了一种7标记物的流式细胞术方案识别外周血中性粒细胞的NETosis(中性粒细胞胞外陷阱的形成),用于分析外周血中性粒细胞的NETosis,能够区分NETotic细胞与坏死细胞,为NETs的量化提供了一种新的、更准确的工具,提高了NETs检测的特异性和准确性。 研究发现,在体外刺激和炎症条件下,所有检测到的NETotic中性粒细胞也表达citrullinated histone H3 (H3cit)。 这项研究不仅推动了对中性粒细胞功能的理解,也为炎症性疾 …
In vitro induction of NETosis: Comprehensive live imaging comparison ...
Our experimental results confirm that under standardized conditions, PMA, living bacteria and Ionomycin all strongly induce NETosis, but real-time confocal imaging reveal different courses of events. Neutrophil extracellular traps (NETs) formation, also called NETosis, is considered one of the defense mechanisms against pathogens [1].
In Vivo Imaging of Neutrophil Extracellular Traps (NETs): …
2020年2月3日 · NETs are fragile fabrics composed of nuclear components and granules, which trap and, in many cases, kill pathogens extracellularly. High-resolution scanning electron microscopy (SEM) has revealed that this fabric (NETs) is composed of smooth stretches and globular domains aggregating into large threads .
