Defense mechanism of insect (Sarcophaga peregrina)

昆虫已经形成了一种独特的防御系统，可以抵御各种外界刺激，如微生物感染和整体伤害。我们一直在研究Peregrina(肉蝇)的各种防御蛋白。这些蛋白质包括一种凝集素和几种抗菌蛋白质。通过这些研究，我们得出结论，这些防御蛋白有两个重要的新方面。其中之一是，单一的防御蛋白可能在防御和发育中至少扮演两个角色。昆虫可能可以灵活地以多种方式使用一种防御蛋白质。另一个有趣的方面是昆虫防御系统的系统发育意义。昆虫防御系统可能是哺乳动物防御系统的原型。除了这两个重要方面，我们还获得了关于昆虫免疫的各种重要发现。这些发现中的大多数已经发表了。

Insect have developed a unique defense system against various outside stimuli such as microbial infection and integmental injury. We have been studying various defense proteins of Sarcophaga peregrina (the flesh fly). These proteins include a lectin and several antibacterial proteins. Throughout these studies, we came to the conclusion that there are two important novel aspects of these defense proteins. One is that a single defense protein probably plays at least two roles in defense and development. Insects probably have the flexibility to use one defense protein in multiple ways. The other interesting aspect is the phylogenetical significance of the insect defense system. Insect defense system is possibly a prototype of the mammalian defense system. Except these two important aspects, we obtained various important findings on insect immnity. Most of these findings have been published.
