[Abstract]  

Insects rely on the simple but effective innate immune system to combat infection. Cellular and humoral responses are interconnected and synergistic in insects’ innate immune system. Phagocytosis is one major cellular response. It is difficult to collect clean hemolymph from the small insect like pea aphid. Here, we provide a practicable method for small insects hemocyte phagocytosis assay by taking pea aphid as an example. Furthermore, we provide the protocols for pea aphid rearing and bacterial infection, which offer referential method for related research.

[摘要]  [摘要]昆虫依靠简单但有效的先天免疫系统来抵抗感染。细胞和体液反应在昆虫的先天免疫系统中是相互联系和协同的。吞噬作用是一种主要的细胞反应。很难从豌豆蚜虫之类的小昆虫身上收集干净的血淋巴。在此,我们以豌豆蚜为例,为小昆虫血细胞吞噬作用测定提供了一种可行的方法。此外,我们提供了豌豆蚜虫饲养和细菌感染的协议我上,这提供了相关的研究参考方法。

[背景技术] 吞噬作用,定义为颗粒大于0.5的细胞摄取微米通过形成膜衍生的吞噬体的,是一种古老的和进化上保守的机制昆虫细胞应答(勒梅特和霍夫曼,2007; Melcarne 。等人,2019a和2019 b)。吞噬作用是由吞噬细胞(专用细胞)介导的,吞噬细胞可以消化“改变自身”的颗粒和病原体(Hillyer和Strand,2014;Melcarne等,2019b)。吞噬细胞不仅可以是血细胞中的循环血细胞,而且可以是组织上的无柄血细胞(Hillyer和Strand,2014; Hillyer,2016; Sigle和Hillyer,2016)。当病原体进入昆虫血腔,吞噬细胞吞噬迅速病理克ENS和吞噬作用通常涂饰在小时(Hillyer等人,2003;王和Hillyer,2012;和事务所Hillyer,2016)。
