NEW TOOLS TO DEVELOP MALARIA VACCINE

描述(改编自申请人摘要)：他们向1个人求婚) 确定疟疾肝期(红外期)的新抗原和新表位 表格(EEF)。用辐射减毒的子孢子免疫可导致 无菌免疫，效应机制是抗体，细胞毒性 淋巴细胞(CTL)和淋巴因子。在血液循环中，抗体附着在 传入的子孢子。如果一些逃逸并进入肝细胞，发育中的 EEF只能被T淋巴细胞或其产物破坏。虽然非常 可取的，由子孢子合成的蛋白质的系统鉴定 并携带到EEF中，或EEF特有的蛋白质，被以下因素阻碍 难以获得这些寄生虫期的纯化制剂。他们 构建了表达绿色荧光蛋白的鼠类疟疾寄生虫(伯氏疟原虫)， 绿色荧光蛋白。FAC排序将允许对 唾液中污染物质产生的高荧光子孢子 蚊子的腺体，以及从大量的蚊子中分离出EEF 未感染的肝细胞。

DESCRIPTION (Adapted from the Applicant's Abstract): They propose to 1) Identify new antigens and epitopes from malaria liver stages (Exo-erythrocytic forms (EEF). Immunization with radiation-attenuated sporozoites leads to sterile immunity, and the effector mechanisms are antibodies, cytotoxic lymphocytes (CTL) and lymophokines. In the blood circulation, antibodies attach the incoming sporozoites. If some escape and enter hepatocytes, the developing EEF can only be destroyed by T lymphocytes or by their products. Though very desirable, the systematic identification of proteins synthesized by sporozoites and carried into the EEF, or of EEF-specific proteins, has been hindered by difficulties in obtaining purified preparations of these parasite stages. They have constructed rodent malaria parasites (Plasmodium berghei) expressing GFP, the green fluorescent protein. FAC sorting will permit the purification of the highly fluorescent sporozoites from the contaminating material in the salivary glands of mosquitoes, and separation of the EEF from the vast numbers of non-infected hepatocytes.
