昆虫血细胞功能、形态及细胞免疫反应研究前沿

Research frontiers of hemocytes functions,morphology and cellular immune response in insects

细胞免疫反应是昆虫先天免疫系统的重要组成部分,与体液免疫反应共同作用以防御外源物。不同类群的昆虫其血细胞种类不同,空间形态及免疫应答功能也各具特征,但在细胞免疫中大都发挥着吞噬、结节与包囊作用。本文根据国内外的研究,对昆虫血细胞的类型、功能、形态、吞噬过程、细胞表面吞噬受体、以蚜虫为代表的不完全变态昆虫免疫学和影响蚜虫免疫系统的共生体等研究动态进行了综述,以期为害虫防治提供思路和防治策略。

Cellular immune response is an important part of the innate immune response in insects,which works together with humoral immune response to protect against pathogens.Different insects have different hemocytes.Although the types,spatial morphology and immune response functions of hemocytes may vary,most of them play the roles of phagocytosis,nodulation and encapsulation in cellular immunity.This paper describes recent progress in insect cellular immunity,including the types,functions,and morphology of insect hemocytes,phagocytosis,cell-surface phagocytic receptors,hemimetabolous immunology and symbionts affecting aphids’immunity.The purpose of this paper is to provide ideas and strategies for pest control.
