凝血可能是导致“长期新冠”症状的根本原因

近日,发表于《血栓与止血杂志》(Journal of Thrombosis and Haemostasis)的一项研究表明,凝血可能是导致一些新冠肺炎患者在感染消失后出现持续数周或数月“长期症状”的根本原因。

研究人员检查了50名“长期新冠”患者,发现相比于健康对照组,“长期新冠”患者血液中的凝血标志物显着升高。在因首次感染新冠肺炎而需要住院治疗的患者中,这些凝血标志物较高。但是,即使那些非住院并且能控制病情的人,凝血标志物仍然居高不下。

研究人员指出,血液高凝状态与“长期新冠”的其他症状直接相关,如身体素质下降和疲劳。尽管炎症标志物均已恢复到正常水平,但这种潜在的血液高凝状态仍存在于“长期新冠”患者中。

新研究发现冠状病毒减毒活疫苗的理想靶点

来源:Emerging Microbes & Infections

近日,发表于《新兴微生物与感染》(Emerging Microbes & Infections)的一项研究提出,N7-甲基转移酶是正向开发冠状病毒减毒活疫苗的理想靶点,且该靶点及机制在冠状病毒属中具有广泛的保守性。

研究团队选取了鼠肝炎病毒(MHV,一种高致病性模式冠状病毒,与SARS-CoV、MERS-CoV、SARS-CoV-2同属于β冠病毒亚属)作为研究模型,利用反向遗传学系统正向开发了N7-甲基转移酶的关键活性位点突变的两株突变病毒rMHVD330A和Y414A,并鉴定了这两株重组减毒病毒的致病性和免疫原性。

研究人员指出,复制稳定的N7-甲基转移酶减毒策略在灭活疫苗的大规模安全生产中也具备应用价值。

新方法可减少新冠病毒测试时间和成本

来源:IScience

近日,发表于IScience的一项工作中,研究人员开发了一种检测新冠病毒的新样本制备方法,该方法绕过了提取病毒的遗传RNA物质,简化了样品的纯化,并有可能减少测试时间和成本。

研究团队收集病人样本后,使用螯合剂Chelex 100树脂来保存样本中新冠病毒RNA,并将它们储存在病毒运输介质或NIH症状测试设施新开发的螯合树脂-缓冲液中。螯合树脂缓冲液中的样本被加热,然后通过RT-qPCR测试病毒RNA。与标准方法相比,新的制备方法大大增加了可用于测试的RNA产量。

mRNA疫苗在接种半年后对6种变异株仍有保护效果

来源:Science

8月12日,发表于《科学》(Science)的一项研究表明,接种两剂Moderna mRNA-1273疫苗后,经过六个月,其诱导的抗体对包括Delta变种在内的6种新冠病毒变异株仍有结合能力与功能性。

志愿者按要求间隔28天接种了2剂mRNA-1273疫苗,并在第一针后4周、第二针后两周、3个月和6个月时提供了血液样本,供研究人员评估其血清对新冠病毒的结合和中和水平。

针对德尔塔变异株,96%的测试样本表现出中和反应,但针对贝塔变种,只有半数测试样本有中和反应,血清中针对贝塔变异株的抗体滴度最低。

疫苗对德尔塔变异株的保护效率下降

来源:NEJM

8月12日,发表于《新英格兰医学期刊》(NEJM)的一项研究公布了英国真实世界的疫苗保护效率数据,结果显示,mRNA疫苗(BNT162b2)和腺病毒载体疫苗(ChAdOx1 nCoV-19)虽然仍能预防德尔塔变异株,但保护效率已经大幅下降。

接种两剂BNT162b2疫苗对德尔塔变异株的保护效率为88.0%,接种两剂ChAdOx1 nCoV-19疫苗的保护效率则为67.0%。而这两款疫苗对新冠病毒原始毒株的保护效率分别为95%和90%。对阿尔法变异株的保护效率分别为93.7%和74.5%。

研究团队表示,尽管保护效率有所下降,但mRNA疫苗和腺病毒疫苗对德尔塔变异株的仍然有较好的保护效率。需要指出的是,仅接种一剂时对德尔塔突变株的保护效率较差,仅为30.7%。

德国推进青少年接种新冠疫苗

8月16日,德国常设疫苗接种委员会(STIKO)在数月的斟酌和评估后,改变了此前较为谨慎的态度,建议所有12至17岁的青少年接种新冠疫苗。该建议得到了德国政界的普遍支持,认为这有利于德国提高疫苗接种率,可以更好地应对第四波新冠疫情。

据罗伯特·科赫研究所(RKI)的数据,与全民超过57.2%的接种率相比,目前德国12至17岁的青少年中仅有24.3%至少接种了一剂,15.1%的人完整接种。而德国儿科感染协会的统计数据显示,德国1400多万少年儿童中已有40万以上的病毒感染确诊病例。

接种灭活疫苗与面瘫有关联

来源:the Lancet Infectious Diseases

8月16日,发表于《柳叶刀·传染病》(the Lancet Infectious Diseases)的一项研究比较了接种不同疫苗引发Bell's palsy(面瘫)的比例,包括国内使用最为广泛的灭活病毒疫苗。

研究人员收集了分别接种BNT162b2和CoronaVac后42天内发生面瘫的数据,结果显示,接种CoronaVac与发生面瘫风险增高相关联,而接种BNT162b2则无关联。但接种疫苗的受益仍远远高于不接种疫苗时面临新冠病毒感染的风险。

首个抗新冠病毒的广谱人源化基因工程单抗展现出良好安全性

来源:Nature Communications

8月17日,发表于《自然·通讯》(Nature Communications)的一项研究中,首次报道了一种靶向多种冠状病毒入侵受体ACE2的阻断抗体;该抗体能够有效预防和治疗新型冠状病毒及其突变株感染宿主细胞及模式动物,并在非人灵长类动物中展现出良好安全性。

研究人员首先通过快速筛选并进行抗体人源化改造,得到一株靶向人ACE2受体的阻断型单克隆抗体h11B11;经过多种冠状病毒的假病毒和真病毒中和评价,证实抗体h11B11对SARS-CoV、SARS-CoV-2及其突变株病毒均具很好的抑制活性;该抗体与微生物研究所早期开发的新冠治疗性抗体CB6联合使用能协同提高中和活性。

疫苗分配不均可能会导致新变种出现

来源:Science

8月17日,发表于《科学》(Science)的一项合作研究发现,疫苗分配不均可能会提高全球新冠病例的数量,并造成新变种的出现,强调了公平、快速的全球疫苗分配的重要性和紧急性。

研究人员预测了在一系列疫苗剂量制度、疫苗接种率和与免疫反应有关的假设下,疫苗高普及率地区和低普及率地区两个模型区域中新冠病例的发病率。

预测结果表明,增加疫苗共享降低了低普及率地区的病例数,并且如果低普及率地区中病例数持续升高,将提高病毒进化的潜力。

接种新冠疫苗的SARS康复者体内会产生更高水平中和抗体

来源:NEJM

8月18日,发表于《新英格兰医学杂志》(NEJM)的一项工作中,研究人员对接种了新冠疫苗的SARS康复者、未接种新冠疫苗的SARS康复者、接种了新冠疫苗的新冠肺炎康复者等5类人群进行了研究,发现接种新冠疫苗的SARS康复者体内,会产生更高水平的抗SARS病毒和新冠病毒的中和抗体。

此外,这些康复者体内的抗体对近期流行的几种新冠变异株,5种来自蝙蝠和穿山甲的同亚属冠状病毒,均具有中和效力。

研究人员指出,新冠疫苗有可能唤醒了免疫系统对SARS病毒和其他病毒共有结构域的“记忆”,从而激活了免疫反应。该研究表明,有可能开发对Sarbecovirus亚属乃至其他冠状病毒有效的广谱疫苗。
