摘要

在豚鼠、家兔、小鼠、猪和牛体内,发现口蹄疫病毒O1-Kaufbeuren主要表位VP1(16,21,31)的三个肽段在130-160个序列范围内以游离和/或载体结合的形式诱导病毒中和抗体。检测了5种载体蛋白,其中甲状腺球蛋白(thyroglobulin)对16肽(145-160)和21肽(141-160 Tyr161)最有效,其次是keyhole帽贝血青蛋白(KLH)。为了保护豚鼠免受口蹄疫,21肽的最小剂量为2 × 8微克。多肽和偶联物的免疫原谱比灭活病毒单价疫苗的免疫原谱更宽。游离肽在体外也能抑制病毒感染。

[Chemosynthetic peptides against foot-and-mouth disease--immune response to free and carrier bound peptides of the VP1 of O1-Kaufbeuren].

Three peptides of main epitope of FMD virus O1-Kaufbeuren, VP1 (16, 21, 31), were found to induce in the 130-160 sequence range, in free and/or carrier-bonded form, virus-neutralising antibodies in guinea pig, rabbit, mouse, swine, and cattle. Five carrier proteins were tested, with thyroglobulin, next to keyhole limpet hemocyanin (KLH), being most effective for 16-peptides (145-160) and 21-peptides (141-160 Tyr161). To protect guinea pig from FMD, minimum dosage of 21-peptide was found to be 2 x 8 micrograms. The immunogenic spectrum of peptides and conjugates proved to be broader than that of monovalent vaccines of inactivated virus. Free peptides were found to be also capable in vitro of inhibiting virus infection.
