环子孢子蛋白(CSP)是疟疾寄生虫子孢子阶段的主要表面蛋白,随着寄生虫发育然后从蚊子中肠迁移到哺乳动物肝脏,具有多种功能。 CSP 的整体结构在疟原虫物种中是保守的,由物种特异性的中央串联重复区域组成,两侧是两个保守的结构域:NH2 末端和 COOH 末端的血小板反应蛋白重复序列​​ (TSR)。尽管中央重复区域是免疫显性 B 细胞表位,也是 III 期临床试验中唯一候选疟疾疫苗的基础,但对其功能作用知之甚少。我们使用啮齿动物疟疾模型伯氏疟原虫来研究 CSP 串联重复区域在子孢子发育过程中的作用。在这里,我们描述了两种突变寄生虫系,一种缺乏串联重复区域 (ΔRep),另一种缺乏 NH2 末端以及重复区域 (ΔNΔRep)。我们表明,在两个突变系中,卵囊形成不受影响,但子孢子发育有缺陷。
The circumsporozoite protein (CSP) is the major surface protein of the sporozoite stage of malaria parasites and has multiple functions as the parasite develops and then migrates from the mosquito midgut to the mammalian liver. The overall structure of CSP is conserved among Plasmodium species, consisting of a species-specific central tandem repeat region flanked by two conserved domains: the NH2-terminus and the thrombospondin repeat (TSR) at the COOH-terminus. Although the central repeat region is an immunodominant B-cell epitope and the basis of the only candidate malaria vaccine in Phase III clinical trials, little is known about its functional role(s). We used the rodent malaria model Plasmodium berghei to investigate the role of the CSP tandem repeat region during sporozoite development. Here we describe two mutant parasite lines, one lacking the tandem repeat region (ΔRep) and the other lacking the NH2-terminus as well as the repeat region (ΔNΔRep). We show that in both mutant lines oocyst formation is unaffected but sporozoite development is defective.
