细菌菌蜕作为新颖药物递送体系的研究进展

Advances on The Novel Drug Deliver System:Bacterial Ghost

细菌菌蜕是革兰氏阴性菌被噬菌体PhiX174的裂解基因E裂解后形成的完整细菌空壳.由于它具有完整的细菌表面抗原结构,所以它能直接作为疫苗使用.利用基因工程手段,可以非常便利地将外源抗原蛋白插入菌蜕的内膜、外膜或周质等多个部位,构建重组菌蜕多价疫苗.目前,菌蜕作为新颖的药物递送体系也开始受到关注.利用菌蜕可以递送DNA和蛋白质疫苗以及其他药物,能较好地产生免疫反应和治疗作用.

Bacterial ghost is intact bacterial envelope which is lysised by the lysis geneE of PhiX174. It can be used as vaccine directly. Foreign antigen can be targeted into outer membrane, inner membrane or the periplasmic space of bacterial, as a result, a recombinant bacterial ghost is constructed. Bacterial ghost, as a novel drug delivery system, is becoming more and more concerned, which can deliver DNA and protein vaccine or other drugs in order to have a better immune responses and therapeutic effects.
