摘要:目的:探讨腐食酪螨和粉尘螨之间是否存在共同抗原.方法:对粉螨过敏患者进行腐食酪螨和粉尘螨特异性IgE相关性分析,用SDS-PAGE分析腐食酪螨和粉尘螨变应原,并对螨特异性IgE阳性血清进行免疫印迹试验及抑制试验.结果:42例粉螨过敏患者血清粉尘螨和腐食酪螨特异性IgE光密度值相关性较高(r=0.641 5,P<0.01).SDS-PAGE分析知腐食酪螨和粉尘螨变应原分子量均为10 kD~110 kD.免疫印迹抑制试验表明,腐食酪螨变应原可与粉尘螨变应原发生交叉反应.结论:腐食酪螨和粉尘螨间存在共同抗原.

Abstract: Objective To investigate whether there is common antigen between Tyrophagus putrescentiae (TP) and Dermatophagoides farine (DF) or not.Methods The correlation of ELISA optic densities between TP and DF-specific IgE in atopic sera was analyzed,and TP and DF extracts were analyzed with SDS-PAGE.IgE immunoblotting and IgE inhibition immunoblotting to TP and DF extracts with atopic sera were performed also.Results  The ELISA optic densities of TP and DF-specific IgE in 42 atopic sera were correlated with each other (r=0.641 5,P<0.01).By SDS-PAGE,the protein components of the TP and DF extracts were numerous protein bands between 10 kD and 110 kD.In addition,the presence of a cross-reactive IgE binding component in the TP and DF major allergens was investigated by IgE inhibition immunoblotting experiments.Conclusion There is common antigen between Tyrophagus putrescentiae and Dermatophagoides farine.

Key words: Tyrophagus putrescentiae, Dermatophagoides farine, common antigen, Acaridida
