表位疫苗研究进展

表位疫苗是近年来发展起来的一种新型疫苗,相对传统疫苗,拥有较多优势。表位疫苗设计的关键是筛选表位,表位的筛选包括蛋白质降解法、肽探针扫描技术、随机肽库技术、计算机表位预测。表位疫苗需要借助一定的载体才能发挥免疫作用,包括脂质载体、蛋白载体、佐剂等。目前国内外学者还采用多种方法如串联重复、MAP空间模式及表位修饰等方法增强表位疫苗的免疫效果。表位疫苗主要包括病毒表位疫苗、细菌表位疫苗和寄生虫表位疫苗。尽管表位疫苗的研究发展迅速,但仍然面临一些问题亟待解决。

Progress on Epitope-Vaccine

Epitope-vaccine is a newly developing vaccine which has many advantages comparied with to the traditional vaccine.The key step for designing epitope-vaccine is to screen epitopes.The epitope-screening methods include protein degration,peptide-probing scanning,epitope prediction by computer,et al.Usually,the epitope-vaccine needs combine some carriers to display immunologic activity,for example,lipid carriers,protein carriers,and adjuvant.In addition,researchers also use tandem repeat epitopes,conformational multiple antigen peptide(MAP) and epitope modifying to strengthen the immunological efficacity.The epitope-vaccine mainly contains viral epitope-vaccine,bacterial epitope-vaccine and epitope-vaccine for parasites.Although the researches on epitope-vaccine develop fast,some problems and challenges need to resolve impendingly.
