近日,第三军医大学科研部生物医学分析测试中心教授万瑛和美国杜克大学免疫学者合作的一项研究,揭开了树突状细胞如何通过蛋白质相互作用完成细胞内囊泡转运以及抗原细胞如何“激活”免疫应答的奥秘。 国际权威期刊《免疫学》(Immunity)杂志刊登了这项研究成果。该研究获得了国家自然科学基金海外及港澳学者研究基金(31028007)、面上项目(31470857)等资助。万瑛表示,正是科学基金对海外及港澳学

近日,第三军医大学科研部生物医学分析测试中心教授万瑛和美国杜克大学免疫学者合作的一项研究,揭开了树突状细胞如何通过蛋白质相互作用完成细胞内囊泡转运以及抗原细胞如何“激活”免疫应答的奥秘。

国际权威期刊《免疫学》(Immunity)杂志刊登了这项研究成果。该研究获得了国家自然科学基金海外及港澳学者研究基金(31028007)、面上项目(31470857)等资助。万瑛表示,正是科学基金对海外及港澳学者研究的资助,让他和杜克大学的研究者有机会合作开展这项研究,从而促进了我国免疫学方面有关囊泡转运的基础科学研究。

瞄准树突状细胞

细胞吞噬作用是机体防御微生物感染的重要机制。上世纪70年代,诺贝尔生理学或医学奖得主拉尔夫·斯坦曼发现,作为一种新型的吞噬细胞,树突状细胞在机体免疫应答过程中发挥着信息交换的作用。

不过,蛋白质等生物大分子不能直接穿过细胞膜,必须依靠膜结构来“穿越”细胞膜。经过长时间的研究,科学家提出了“囊泡转运”的概念,即大分子物质进出细胞的过程由膜包裹、形成囊泡、与膜融合或断裂组成。

树突状细胞则通过复杂的囊泡转运,解析入侵病原体信息,启动获得性免疫。在研究者们看来,能深入了解树突状细胞囊泡转运过程,感染性疾病的治疗就有了科学基础。

万瑛介绍,据世界卫生组织统计,目前每年约有800万由结核分枝杆菌感染引起的结核病例发生,导致上百万人死亡。而结核分枝杆菌、伤寒沙门氏菌和李斯特菌等也严重威胁着人类健康。

“树突状细胞不仅能产生大量与免疫应答有关的细胞因子,还能摄取和处理抗原,进而启动机体免疫应答。”万瑛说,“厘清树突状细胞与病原菌相互作用的细胞生物学基础仍有许多问题需要阐明。”

描绘囊泡转运过程

“想要了解树突状细胞的囊泡转运如何精确完成,就必须知道有哪些蛋白参与到这个过程中以及这些蛋白进行了怎样的相互作用。”

2009年前后,万瑛带领研究小组,采用RNA干扰技术大规模地筛选出与细胞内囊泡转运相关的蛋白家族,发现了12个与树突状细胞“激活”免疫应答有关的蛋白,被称为“Rab”蛋白。相关工作发表在《美国科学院院刊》(PNAS)上。

在此基础上,研究人员又发展了新型串联亲和纯化技术,鉴定了与囊泡转运相关的一种“Rab蛋白”家族的相互作用。

万瑛指出:“我们通过这一结果绘制出一幅描述树突状细胞囊泡转运的‘地图’。”

研究小组详细解析了Rab32蛋白关联网络的功能,发现Rab32-PHB-PHB2蛋白复合体参与树突状细胞清除感染的“李斯特细菌”。这一复合体位于包裹李斯特细菌的囊泡上,能够限制李斯特细菌的复制。

而结合超分辨显微镜和双束扫描电镜技术,研究小组首次发现逃逸吞噬体的李斯特细菌被Rab32阳性囊泡再次包裹,揭示了细胞针对逃逸吞噬体细菌的第二波膜性防御机制。

J Immunol:利用人胚胎干细胞生成DC抗肿瘤

    近日,新加坡生物工程与纳米技术研究所开展的一项研究利用人类胚胎干细胞(胚胎干细胞)生成树突状细胞(DC)来刺激免疫系统来抗肿瘤,该新方法可能是一个更经济方式来生成抗癌症的治疗性疫苗。     树突状细胞提呈刺激免疫应答的抗原物质,以刺激免疫系统的其他细胞消除致病细胞。DCs的这种能力使得树突状细胞是疫苗在体内的理想选择作用靶细胞

树突状细胞阻断而非促进采用新佐剂的幽门螺杆菌免疫

来源:医学论坛网   最近,瑞士学者Iris Hitzler等研究发现,在使用分枝杆菌作为佐剂的幽门螺杆菌(H pylori)疫苗肠外免疫中,树突状细胞起阻断而非促进作用。相关内容发表于《胃肠病学》(Gastroenterology)杂志。   针对胃H pylori的免疫可以预防多种胃癌和其他类型的疾病。在临床前模型中使用的接种疫苗的流程,并不适合于人体。新的佐剂以及对疫苗诱导保护作用的更好

日前,《科学》Science杂志上分别刊登了来自中国学者的两篇文章。来自来自第二军医大学、中国医学科学院和浙江大学医学院的曹雪涛(Xuetao Cao)院士等人首发现一种名为 lnc-DC 的长链非编码 RNA 控制了人类树突状细胞的分化;而来自中科院微生物研究所高福则发表了一篇社论,谈到了关闭活禽市场的必要性。 在第一项研究中,来自第二军医大学、中国医学科学院和浙江大学医学院的研究人员,发

Nature:树突状细胞分子刹车在抗肿瘤免疫中的作用

在小鼠的卵巢癌模型中,激活树突状细胞的应激反应和转录因子XBP1,能抑制树突状细胞抗肿瘤免疫的作用。 肿瘤微环境中的细胞时刻暴露于各种刺激之下。这部分可归因于缺氧和缺乏营养导致的内质网功能失常。内质网是负责蛋白质折叠的细胞器。内质网功能失调后,细胞内错误折叠蛋白堆积——也就是所谓的内质网应激。癌症细胞通过内质网应激能从缺氧缺营养的环境中生存下来。科学家们目前仍不清楚,这条通路是否影响肿瘤微
