结核病是一种严重危害人类健康的重大传染病,由于BCG预防效果不佳,研制新型结核病疫苗迫在眉睫。研究开发新型结核病疫苗应根据机体抗结核杆菌感染的免疫应答特点、结合BCG的不足来开展。新型结核病疫苗主要分为三类:重组BCG或重组结核菌;重组痘病毒或重组腺病毒载体疫苗;蛋白抗原亚单位或重组融合蛋白抗原亚单位疫苗。由于蛋白亚单位疫苗可以不受机体已被分枝杆菌刺激的影响,能特异性地诱导CD4+Th1细胞和CD8+细胞毒性T细胞活化,并且使用安全性好,而备受研究者的青睐。目前主要是以BCG或重组BCG初次免疫,然后选择亚单位疫苗加强免疫作为结核病疫苗序贯免疫策略。然而,单个蛋白制成亚单位疫苗,其免疫效果有限,因此将多个具有保护效果的抗原或多肽表达成融合蛋白,联合适当的佐剂,制成融合蛋白亚单位疫苗。目前,已有一些融合蛋白亚单位疫苗进入临床试验阶段,更多的融合蛋白正处于研究阶段。
結覈病是一種嚴重危害人類健康的重大傳染病,由于BCG預防效果不佳,研製新型結覈病疫苗迫在眉睫。研究開髮新型結覈病疫苗應根據機體抗結覈桿菌感染的免疫應答特點、結閤BCG的不足來開展。新型結覈病疫苗主要分為三類:重組BCG或重組結覈菌;重組痘病毒或重組腺病毒載體疫苗;蛋白抗原亞單位或重組融閤蛋白抗原亞單位疫苗。由于蛋白亞單位疫苗可以不受機體已被分枝桿菌刺激的影響,能特異性地誘導CD4+Th1細胞和CD8+細胞毒性T細胞活化,併且使用安全性好,而備受研究者的青睞。目前主要是以BCG或重組BCG初次免疫,然後選擇亞單位疫苗加彊免疫作為結覈病疫苗序貫免疫策略。然而,單箇蛋白製成亞單位疫苗,其免疫效果有限,因此將多箇具有保護效果的抗原或多肽錶達成融閤蛋白,聯閤適噹的佐劑,製成融閤蛋白亞單位疫苗。目前,已有一些融閤蛋白亞單位疫苗進入臨床試驗階段,更多的融閤蛋白正處于研究階段。

Due to the poor effect of BCG , tuberculosis remains a leading infectious disease , it is a very urgent need to de-veloping a new tuberculosis (TB) vaccine.The research and development of new TB vaccines should be based on the char -acteristics of the body's immune response against Mycobacterium tuberculosis infection, and help to overcoming the short-coming of BCG.New TB vaccines include the recombinant BCG or attenuated Mycobacterium tuberculosis, vaccinia virus or recombinant adenovirus used as carriers in the recombinant vaccines ,and the protein antigen or recombinant protein subunit vaccines .It is the protein subunit vaccine which can not be affected in the individual that has been stimulated by the myco -bacteria , so the specifically activation of CD 4+Th1 cells and CD8+CTL cells can be induced ,as well as good safety in use , thus this type of vaccine is widely focused by researchers .Current strategy for the vaccination is priming with BCG or re-combinant BCG followed by boosting with a subunit vaccine .However, the immune effect from a single protein subunit vac-cine is limited, so a fusion protein subunit vaccine with multiple protective antigens or peptides and accompanied by a suit -able adjuvant is developed .At present, some fusion protein subunit vaccines have been applied in clinical trials , and many are under research stage .
