Science TM:表达Ag85A的复制缺陷的腺病毒载体5疫苗可能具有强大抗结核病作用

2013-10-22 新华网 新华网

加拿大麦克马斯特大学研究人员最近研发出一种结核病疫苗,这一成果有望取代目前唯一且已使用了50年的结核病疫苗——卡介菌苗(BCG),研究结果在日前出版的《科学—转化医学》杂志上发表,论文显示新疫苗十分安全且对结核病有强大免疫效果。这种疫苗由表达Ag85A的复制缺陷的腺病毒载体5疫苗AdHu5Ag85A ,具有强大刺激T细胞免疫的机能。 结核病是全世界仅次于艾滋病的第二大致命传染病。据统计,世界上三

加拿大麦克马斯特大学研究人员最近研发出一种结核病疫苗,这一成果有望取代目前唯一且已使用了50年的结核病疫苗——卡介菌苗(BCG),研究结果在日前出版的《科学—转化医学》杂志上发表,论文显示新疫苗十分安全且对结核病有强大免疫效果。这种疫苗由表达Ag85A的复制缺陷的腺病毒载体5疫苗AdHu5Ag85A ,具有强大刺激T细胞免疫的机能。

结核病是全世界仅次于艾滋病的第二大致命传染病。据统计,世界上三分之一的人口受到结核杆菌的感染。世界卫生组织报告称结核病在2011年造成140万人死亡,870万人患病。另外,结核杆菌的抗药性越来越强,这也使得结核病的预防变得愈发重要。

加拿大西多伦多医院结核病诊所创办人兼主管Michael Gardam博士说:“结核病菌与人体免疫系统有着十分复杂的关系。这也给发现对抗它的疫苗带来很多困难。”研究人员用了10年时间来研究新疫苗,24位志愿者曾接种了新疫苗。在最早的研究中,新疫苗是以手臂注射的形式接种,研究人员计划开发一个可以将疫苗直接吸入肺部的装置,这将使预防更加有效。
