Abstract

Using the predictive algorithm of Rothbard and Taylor (1988. EMBO J. 7:93) and the primary structure of gp63 (Button, L., and M.R. McMaster. 1988. J. Exp. Med. 167:724; Miller, R.A., S.G. Reed, and M. Parsons. 1990. Mol. Biochem. Parasitol. 39:267) we have been able to delineate the structures of a number of gp63 T-cell epitopes which stimulate the proliferation of CD4+ cells. One of these synthetic antigens, inoculated subcutaneously with adjuvant, was shown to specifically induce proliferation of the Th1 subset and provided immunoprotection against two species of Leishmania parasites.

摘要

利用罗斯巴德和泰勒(1988年,《欧洲分子生物学组织杂志》第7卷:93页)的预测算法以及gp63的一级结构(巴顿,L.,和M.R.麦克马斯特。1988年,《实验医学杂志》第167卷:724页;米勒,R.A.,S.G.里德,和M.帕森斯。1990年,《分子生物化学寄生虫学》第39卷:267页),我们已经能够描绘出一些刺激CD4 +细胞增殖的gp63 T细胞表位的结构。其中一种合成抗原,与佐剂一起皮下接种,被证明能特异性诱导Th1亚群的增殖,并提供针对两种利什曼原虫寄生虫的免疫保护。
