传染性 灭活疫苗 北京大学基础医学院
2023/8/11
在南非发现的Omicron新冠变异株具有高度的传染性和显著的传播优势,是目前导致新冠肺炎病例剧增的主要变异株。与Wuhan-Hu-1病毒株相比,Omicron的S基因包含多达30个突变位点,突出的免疫逃逸对疫苗接种后的效力和免疫保护效果造成了严峻挑战。国内外基于mRNA疫苗的加强免疫方案的广泛报道显示,针对Omicron的中和抗体反应强度和滴度均显著下降。 新冠灭活疫苗具有诱导抗体广泛、安全性高、...

研究发现纤维蛋白原具有抗炎作用(图)
纤维蛋白 抗炎作用 生物氧化剂
2021/3/1
近日,来自澳大利亚弗林德斯大学健康与医学研究所和医学与公共卫生学院的研究人员发现血纤维蛋白的一种新的抗炎作用,可以为肾脏、心脏和其他常见疾病的治疗提供新的方法。纤维蛋白原是血浆的主要成分,极容易与生物氧化剂发生反应。氯酸盐是人体在炎症过程中产生的一种化学物质。这项研究描述了纤维蛋白原是如何保护人体免受次氯酸盐的侵害,因此在血浆中起着抗氧化的作用。这项研究近日于《Redox Biology》发表,题...

据印度媒体报道,印度一个研究小组新发现了结核病细菌产生耐药性的机制,并成功通过一种药物组合阻止这种耐药机制被激活,通过两个月治疗就几乎完全清除了小鼠肺部的细菌,且可有效降低复发感染概率。结核病是由结核杆菌引起的慢性传染病,在印度的发病率和死亡率都较高。据《印度教徒报》近日报道,印度科学研究所传染病研究中心阿米特·辛格领导的研究团队发现,通过联合使用抗疟疾药物氯奎与结核病药物异烟肼,在8周内可基本清...
英国剑桥大学和瑞典隆德大学研究人员发现,胆固醇可能在阿尔茨海默病形成和发展过程中起到催化剂作用。先前研究显示,大脑中贝塔淀粉状蛋白大量积聚是导致阿尔茨海默病的直接原因。实际上,所有脑细胞都会生成贝塔淀粉状蛋白。研究牵头人、剑桥大学学者米歇尔·文德鲁斯科洛说,正常情况下,大脑中的贝塔淀粉状蛋白水平几乎是实验室积聚要求的千分之一,“到底发生了什么让它积聚?”研究人员在体外研究中发现,大脑神经元细胞膜中...
