无脊椎动物的免疫与包括细胞和体液元素在内的自然机制相关,类似于在脊椎动物先天免疫反应中发挥作用的机制。细胞外陷阱(ET)的形成是一种新发现的对抗病原体的机制,不仅在脊椎动物白细胞中起作用,而且在无脊椎动物免疫细胞中也起作用。 ET 成分包括细胞外 DNA (exDNA)、抗菌蛋白和组蛋白。哺乳动物 ET 的形成取决于中性粒细胞弹性蛋白酶、髓过氧化物酶、组蛋白瓜氨酸化和蛋白酶活性等酶。已证实,体腔细胞(蚯蚓 Eisenia andrei 的免疫活性细胞)也能够以蛋白酶依赖性方式释放 ET,依赖或独立于活性氧的形成和细胞骨架的重排。与脊椎动物白细胞(例如中性粒细胞)类似,体腔细胞负责许多免疫功能,如吞噬作用、细胞毒性和体液因子的分泌。由中性粒细胞 ET 的体腔细胞类似物形成的 ET 由 exDNA、组蛋白 H3 和附着在这些结构上的蛋白质组成,例如热休克蛋白 HSP27。后一个事实证实了 ET 释放机制在进化中是保守的。对环节动物的研究将这一动物群添加到能够释放 ET 的无脊椎动物名单中,但最重要的是提供了低等动物类群中 ET 形成的先天机制的内部信息。
Invertebrate immunity is associated with natural mechanisms that include cellular and humoral elements, similar to those that play a role in vertebrate innate immune responses. Formation of extracellular traps (ETs) is a newly discovered mechanism to combat pathogens, operating not only in vertebrate leucocytes but also in invertebrate immune cells. The ET components include extracellular DNA (exDNA), antimicrobial proteins and histones. Formation of mammalian ETs depends on enzymes such as neutrophil elastase, myeloperoxidase, the citrullination of histones and protease activity. It was confirmed that coelomocytes—immunocompetent cells of the earthworm Eisenia andrei—are also able to release ETs in a protease-dependent manner, dependent or independent of the formation of reactive oxygen species and rearrangement of the cell cytoskeleton. Similar to vertebrate leukocytes (e.g., neutrophil), coelomocytes are responsible for many immune functions like phagocytosis, cytotoxicity and secretion of humoral factors. ETs formed by coelomocyte analogues to neutrophil ETs consist of exDNA, histone H3 and attached to these structures proteins, e.g., heat shock proteins HSP27. The latter fact confirms that mechanisms of ET release are conserved in evolution. The study on Annelida adds this animal group to the list of invertebrates capable of ET release, but most importantly provides insides into innate mechanisms of ET formation in lower animal taxa.
