摘  要:
【目的】预测埃及伊蚊Aedes aegypti表皮结构蛋白AaCPR100A的抗原表位。【方法】通过DNAStar 8的Protean软件对埃及伊蚊表皮结构蛋白AACPR100A的二级结构和亲疏水性、表面可及性、柔韧性等特性进行分析,预测其潜在的B细胞抗原表位和潜在的T细胞抗原表位。【结果】AaCPR100A蛋白的二级结构以转角和不规则卷曲为主,表面可及性、柔韧性较强,存在7个潜在的B细胞抗原表位,位于18-29、32-42、47-82、87-98、111-178、194-248氨基酸残基或其附近,同时有11个潜在的T细胞抗原表位,位于20-24、35-39、44-48、51-53、79-82、103-106、109-112、146-148、150-152、185-203、224-235氨基酸残基或其附近。【结论】AaCPR100A蛋白潜在的B细胞抗原表位有7个,潜在的T细胞抗原表位有11个,综合后有3个潜在抗原表位,预测结果将为进一步研究AaCPR100A蛋白的免疫学特性和功能奠定基础,并为蚊虫的控制提供潜在的靶标。

摘  要:
[Objectives] To predict the epitopes of the Aedes aegypti epidermis protein AaCPR100A. [Methods] The secondary structure and hydrophobicity, surface probability and flexible regions of AaCPR100A were analyzed by DNAstar software to predict potential B cell antigen epitopes and potential T cell antigen epitopes. [Results] The secondary structure of the AaCPR100A protein was rich in β-turns and random coils, and had high surface probability and flexibility. There were 7 potential B cell epitopes located at amino acid residues 18-29, 32-42, 47-82, 87-98, 111-178 and 194-248, or nearby, and also 11 potential T cell epitopes located at amino acid residues 20-24, 35-39, 44-48, 51-53, 79-82, 103-106, 109-112, 146-148,150-152, 185-203 and 224-235, or nearby. [Conclusion] The AaCPR100A protein contains both potential B cell antigen epitopes and potential T cell antigen epitopes. The predicted results provide a foundation for studies of the immunological properties and function of the AACPR100A protein, and suggest a potential target protein for mosquito control.
