非洲锥虫是人类和动物几种重要疾病的罪魁祸首。这些寄生原生动物成功地与其哺乳动物宿主的免疫系统竞争的方式之一是通过一种被称为抗原变异的现象(在Donelson和Rice-Ficht,1985;Pays,1985;Boothroyd,1985)中回顾了这一现象。这描述了它们改变表面涂层的抗原成分的能力,当寄生虫在宿主的血液中时,表面涂层完全包围寄生虫。在任何一个锥虫上,在任何时候,这种被毛基本上是均一的,由一种单一的糖蛋白组成,称为变异表面糖蛋白或VSG(Cross,1975;Vickerman and Luckins,1969)。
The african trypanosomes are responsible for several important diseases of humans and animals. One of the ways in which these parasitic protozoa successfully compete with the immune system of their mammalian hosts is through a phenomenon known as antigenic variation (reviewed in Donelson and Rice-Ficht, 1985; Pays, 1985; Boothroyd, 1985). This describes their ability to alter the antigenic composition of the surface coat which completely envelops the parasites while in the bloodstream of the host. On any one trypanosome, at any one time, this coat is essentially homogeneous, being comprised of a single glycoprotein species, known as the variant surface glycoprotein or VSG (Cross, 1975; Vickerman and Luckins, 1969).
