摘要: 食物致敏原是引起食物过敏的元凶,多为蛋白质。抗原表位是在抗原分子中与抗体反应或被抗原受体识别,并引发机体免疫应答的特殊化学基团。从表位水平认识食物致敏原,能揭示食物过敏的物质基础,为解决食物过敏问题提供精准的靶标。本文基于表位结构和定位方法的不同,介绍了食物致敏原表位定位技术的发展,并进一步展望了致敏原表位信息对于改进食物过敏鉴定技术和低致敏食物加工方法的应用前景。

Abstract: Food allergens are the major causes of food allergies, which are mainly proteins. The antigen epitope is a special chemical group in the antigen molecule, which can react with antibody or be recognized by the antigen receptor, and trigger the body’s immune response. Understanding food allergens at the epitope level can reveal the material basis of food allergic reactions and provide precise targets for solving the problem of food allergy. This paper reviews the development of food allergen epitope localization technologies based on different epitope structures and localization methods, and discusses further prospects for the application prospects of allergen epitope information for improving the existing food allergen identification technologies and hypoallergenic food processing methods.

Key words: food allergen; epitope mapping; T cell epitope; B cell epitope; linear epitope; conformational epitope
