Neutrophil extracellular trap (NET) formation is a hallmark of many disorders that involve neutrophil recruitment, tissue damage, and inflammation. As NET formation is often associated with neutrophil death, the term "NETosis" has become popular. Upon discovery that neutrophils may survive NET release, apparent misnomers, such as "vital NETosis," have been proposed. Meanwhile, it has become obvious that certain stimuli can trigger neutrophil necroptosis, a process associated with NET-like chromatin release. Here, we discuss the relationship between NET release and neutrophil death in view highlighting that many assays used in the field do not properly distinguish between the two. An updated nomenclature is needed replacing the term "NETosis" to meet the growing variety of settings leading to chromatin release with and without neutrophil death. Dissecting which triggers of NET release involve which signaling pathway will help to define drugable molecular targets that inhibit NET release and/or neutrophil necrosis in specific disorders.
中性粒细胞胞外陷阱(NET)形成是许多涉及中性粒细胞募集、组织损伤和炎症的疾病的一个标志。由于NET形成常与中性粒细胞死亡相关,“NETosis”一词已被广泛使用。在发现中性粒细胞可能在释放NET后存活后,有人提出了一些明显的误称,如“存活NETosis”。与此同时,很明显某些刺激可触发中性粒细胞坏死性凋亡,这是一个与NET样染色质释放相关的过程。在此,我们讨论NET释放与中性粒细胞死亡之间的关系,强调该领域中使用的许多检测方法不能很好地区分这两者。需要一个更新的命名法来取代“NETosis”一词,以适应导致染色质释放且有无中性粒细胞死亡的越来越多的情况。剖析哪些NET释放触发因素涉及哪些信号通路,将有助于确定在特定疾病中抑制NET释放和/或中性粒细胞坏死的可药物化分子靶点。
