通过反复接种辐照过的子孢子,从鸟类到人类的宿主都获得了抗疟疾的保护性免疫。参与对子孢子的保护性免疫的主要抗原是环子孢子(CS)蛋白,其是蛋白家族的一部分,覆盖寄生虫的整个表面膜,并且具有相似的物理化学和抗原性质。抗CS蛋白的单克隆抗体的单价片段中和子孢子的感染性。所有单克隆抗体识别各种CS蛋白内的单个免疫显性区域,并且该区域含有重复表位。诺氏疟原虫CS蛋白的重复免疫显性表位已被鉴定,并显示由12个串联重复的12个氨基酸亚基组成。将十二肽的二聚体偶联到蛋白质载体上,在弗氏完全佐剂中乳化,并注射到啮齿动物和猴子中。所有动物均产生抗肽抗体,且大多数抗血清与诺氏疟原虫CS蛋白反应。
Protective immunity against malaria has been achieved in hosts ranging from birds to man by repeated inoculation of irradiated sporozoites. The main antigens involved in protective immunity to sporozoites are the circumsporozoite (CS) proteins, which are part of a family of proteins, covering the whole surface membrane of the parasite, and which have similar physico-chemical and antigenic properties. Monovalent fragments of monoclonal antibodies to CS proteins neutralize sporozoite infectivity. All monoclonal antibodies recognize a single immunodominant region within the various CS proteins, and this region contains repetitive epitopes. The recurrent immunodominant epitope of the CS protein of P. knowlesi has been identified, and shown to consist of 12 tandemly repeated subunits of 12 amino acids. The dimer of the dodecapeptide was coupled to protein carriers, emulsified in Freund's complete adjuvant, and injected into rodents and monkeys. All animals made anti-peptide antibodies, and most of the antisera reacted with P. knowlesi CS protein.
