摘要: 细胞免疫是昆虫天生免疫系统中很重要的部分, 包括了由血细胞介导的一系列吞噬、 集结和包囊等作用。本文讨论了近年来在昆虫细胞免疫方面的研究进展, 包括参与昆虫细胞免疫的血细胞类型, 识别外来异物的受体因子, 影响免疫活性的一些酶和化学物质等。另外还就吞噬模式, 以及集结和包囊过程中粘附态细胞的形成等加以讨论。

Abstract: Cellular immunity that includes phagocytosis, nodulation and encapsulation mediated by hemocytes is a very important part of the innate immune system in insects. In this article we reviewed the current understanding of cellular immune responses in insects. We summarized the hemocyte types involved in cellular immunity, some cellular receptors that recognize different microbes and multicellular parasites, and some enzymes and chemicals that can affect the immune activity. We also discussed the modes of hemocyte-mediated phagocytosis and the morphological change of hemocytes during the progress of nodulation and encapsulation.

Key words: Insect, immune response, cellular immunity, hemocytes, phagocytosis, nodulation, encapsulation
