Nanomedicine:巨噬细胞为中枢神经系统输送治疗性蛋白提供开关

活化的靶向的输送纳米配制的氧化还原酶、过氧化氢酶,在帕金森病动物模型中巨噬细胞的氧化应激变弱,却增加了多巴胺能神经元的存活。优化的药物配方在活细胞中成功的输送是至关重要的。我们早些时候证明将过氧化氢酶融入带有一种合成聚电解质嵌段共聚物的聚离子复合胶束(纳米酶)中,保护酶在巨噬细胞中降解,改善治疗的结果。我们现在报告制造的具有优越结构和疗效指数的纳米酶。 合成、表征和最佳细胞的纳米配方的治疗效果得

活化的靶向的输送纳米配制的氧化还原酶、过氧化氢酶,在帕金森病动物模型中巨噬细胞的氧化应激变弱,却增加了多巴胺能神经元的存活。优化的药物配方在活细胞中成功的输送是至关重要的。我们早些时候证明将过氧化氢酶融入带有一种合成聚电解质嵌段共聚物的聚离子复合胶束(纳米酶)中,保护酶在巨噬细胞中降解,改善治疗的结果。我们现在报告制造的具有优越结构和疗效指数的纳米酶。

合成、表征和最佳细胞的纳米配方的治疗效果得到评估。

配方设计药物载体通常工作来避免在单核细胞和巨噬细胞中的截留,专注于伴有聚乙二醇冠状物的小型纳米颗粒。相比之下,巨噬细胞输送的最佳的纳米酶在这项研究中所报告的,有一个相对较大的大小尺寸(约200 nm),这将提高负载量,从巨噬细胞中释放。此外, 伴有多余的非生物降解的链接器的交联纳米酶确保其细胞毒性低, 在细胞的载体中高效的过氧化氢酶保护。最后,任一激活的巨噬细胞表型(M2)用于这些研究并没有进一步促进脑部炎症, 在体内的神经再生和修复上导致一个微妙但显著的影响。

优化交联纳米酶加载到巨噬细胞,在老鼠模型上减少了神经炎症反应,增加了神经元的存活。重要的是,细胞介导输送的纳米配方设计方案不同于常见的注射制剂的要求。

PLOS Pathogens:良性细菌如何进化为致命病原菌

细菌能够迅速进化为使自己适应环境的变化。当“环境” 是一个感染宿主的免疫反应时,这种进化可以使无害的细菌变成威胁生命的病原菌。发表在12月12日的PLOS Pathogens杂志上的一项研究,深入探讨了这一过程是如何发生的。【原文下载】 葡萄牙Gulbenkian de Ciencia 研究所的Isabel Gordo和同事们,

JCB:巨噬细胞可“赶走”中性粒细胞促进机体炎症修复

巨噬细胞是我们机体中强大的“吃豆小精灵”,其可以吞咽细胞残渣及病原体来保护机体健康,近日,一篇刊登在国际杂志The Journal of Cell Biology上的研究论文中,来自威斯康辛-迈迪逊大学大学的研究人员揭示了巨噬细胞如何通过诱导中性白细胞,使其离开机体损伤的组织进而帮助治疗炎症。 中性粒细胞是机体中的“第一急救者”,其可以被名为活性氧激活的蛋白激酶所吸引到患处,当中性粒细胞完成

ATVB:缺失蛋白或可抑制动脉硬化

近日,一项由Jason Johnson 博士领导的研究项目由英国心脏基金会资助(BHF),Jason Johnson 博士是布里斯托尔大学临床科学学院的高级研究员,相关文章发表在《动脉硬化、血栓和血管生物学》杂志上。 巨噬细胞对供给心脏血液的动脉是非常重要的,但动脉在给心脏供给血液的同时会累积脂肪,这一过程称为动脉粥样硬化。动脉粥样硬化病会导致动脉功能被削弱并且会使动脉管上产生裂纹,这样就

Nature:分枝杆菌分辨不同巨噬细胞的方式

在其最初感染点上,结核病病原体感染巨噬细胞,后者将该细菌输送到更深的组织。该细菌在这些宿主细胞内是怎样生存的却不清楚。 在这项研究中,Lalita Ramakrishnan及同事发现,结核分枝杆菌及其致病性近亲海洋分枝杆菌进化出了一个避开杀菌性巨噬细胞、同时招募那些允许它们生存的巨噬细胞的策略。 这种偏向性的招募是通过两个步骤完成的:第一,该细菌通过生成“分枝杆菌结核菌醇双结核蜡酸酯”脂质来掩

Immunity:VEGFR-3抑制巨噬细胞通路TLR4-NF-κB

3月21日,国际学术期刊IMMUNITY(《免疫》)在线发表了中国科学院上海生命科学研究院生物化学与细胞生物学研究所王红艳研究组的论文。该研究发现巨噬细胞受细菌感染或细菌脂多糖LPS刺激后,升高血管内皮生长因子受体3(VEGFR-3)的表达。VEGFR-3形成负反馈环路,抑制TLR4-NF-κB介导的炎症反应,降低细菌感染导致的败血症或内毒素休克的发生。该项工作在探寻TLR4通路中新型阴性调控分子

Science:药物组合帮巨噬细胞“吃掉”肿瘤

在合成SIRPα蛋白(CV1单核细胞)和抗癌药物利妥昔单抗的双重打击下,小鼠体内的肿瘤在29天后被清除。图片来源:K. Weiskopf等 为了避免被免疫系统破坏,癌细胞耍了一些小手段。当它们分裂形成肿瘤时,会避免让巨噬细胞察觉到,巨噬细胞是从事消灭死亡细胞和危险入侵者的免疫细胞。现在,许多癌症患者都在利用抗体药物进行治疗,这些抗体药物的部分作用是标识肿瘤细胞以便让巨噬细胞消灭它们。尽管这些
