Carbohydrate structures that decorate the surface of cells are increasingly recognized as playing important roles in the biology of host-pathogen interactions. Plasmodium species have undergone a process of gene loss that has removed much of their capacity to produce complex glycoconjugates or glycosylated proteins other than the glycosylphosphatidyinositol (GPI) moiety that anchors the surface proteins of infective stages, including the merozoite. Instead, these parasites have elaborated a set of proteins with lectin-like properties that interact with mammalian and insect cell surfaces. An overview of this and other aspects of the glycobiology of Plasmodium is presented here.
修饰细胞表面的碳水化合物结构在宿主与病原体相互作用的生物学过程中所起的重要作用日益受到认可。疟原虫经历了一个基因丢失的过程,除了用于锚定包括裂殖子在内的感染阶段表面蛋白的糖基磷脂酰肌醇(GPI)部分外,它们产生复杂糖缀合物或糖基化蛋白的能力已大幅丧失。相反,这些寄生虫进化出了一组具有凝集素样特性的蛋白质,可与哺乳动物和昆虫细胞表面相互作用。本文将概述疟原虫糖生物学的这一方面及其他方面。
