A series of overlapping peptides, representing sequences in the vicinity of region II on the Plasmodium vivax circumsporozoite protein, was synthesized. One of the peptides (PV-23), a 20-mer containing the 6 C-terminal amino acids of region II, was found to evoke an in vitro T-cell proliferative response in spleen cells from C3Hf (H-2km2) mice immunized with the peptide. These results demonstrate that PV-23 contains a T-cell epitope. To our knowledge, this is the first report of a T-cell epitope on the circumsporozoite protein of P. vivax.
合成了一系列重叠肽，这些肽代表间日疟原虫环子孢子蛋白上区域II附近的序列。其中一种肽（PV-23）是一个含有区域II的6个C末端氨基酸的20肽，在用该肽免疫的C3Hf（H-2km2）小鼠的脾细胞中发现它能引发体外T细胞增殖反应。这些结果表明PV-23含有一个T细胞表位。据我们所知，这是关于间日疟原虫环子孢子蛋白上T细胞表位的首次报道。
