目的:1.鉴定疟原虫红细胞侵入受体和感染红细胞粘附于内皮和胎盘的受体。2.确定每种寄生虫受体的红细胞配体。3.鉴定与胎盘结合的变异抗原的最小结构域。4.测试变异抗原上的一个区域,用于诱导Aotus猴对恶性疟原虫的保护和克服变异。5.鉴定诱导抗体阻断感染的恶性疟原虫蛋白。 本年度取得的成绩:1。已鉴定出一种切割寄生虫受体的膜内蛋白酶Rhomboid。2.唾液酸结合位点已在BAEBL(一种寄生虫受体)上鉴定。
英文摘要
Purpose: 1. To identify the receptors on malaria parasites for red cell invasion and on infected red cells for adhesion to endothelium and to placenta. 2. To identify the red cell ligands for each parasite receptor. 3. To identify the minimal domain in the variant antigen for binding to placenta. 4. Test a region on the variant antigen for inducing protection against P. falciparum in Aotus monkeys and for overcoming variation. 5. Identify P. falciparum proteins that induce antibodies to block infection. Accomplishments during the year: 1. Rhomboid, an intramembrane protease that cleaves parasite receptors, has been identified. 2. The sialic acid binding site has been identified on BAEBL, a parasite receptor.
