Two synthetic peptides, corresponding to the N-terminal sequence of the 45-kDa subunit of the protective 9B antigen of Schistosoma mansoni and differing in only one amino acid residue, were synthesized. These peptides were recognized by the protective monoclonal antibody 152-66-9B, as well as by sera of mice and humans infected with schistosomiasis. The peptides were coupled to a protein carrier and used for immunization. One of the peptides, 9B-peptide1, induced in mice significant protection against challenge infection, manifested in a 40 to 50% reduction in worm burden.
合成了两种对应于曼氏血吸虫保护性9B抗原45 kDa亚基N端序列且仅一个氨基酸残基不同的合成肽。这些肽能被保护性单克隆抗体152 - 66 - 9B以及感染血吸虫病的小鼠和人类血清所识别。将这些肽与蛋白质载体偶联并用于免疫。其中一种肽,9B - 肽1,在小鼠中诱导出对攻击感染的显著保护作用,表现为虫体负荷降低40%至50%。
