mutations in the spike protein of SARS-CoV-2, which binds to receptors on cells lining the inside of the human nose, may make the virus easier to spread or affect how well vaccines protect people.

Since the outbreak of COVID-19, countries all over the world have suffered severe losses. It affects not only human life and health but also the economy. In response to COVID-19, countries have made tremendous efforts to vaccine development. The newly discovered variants of SARS-CoV-2 have...
SARS-CoV-2 (severe acute respiratory syndrome coronavirus-2), the causative agent ofCOVID-19, was first reported in Wuhan (China) and has rapidly disseminated around the globe [1]. Only one year after the pandemic outbreak, scientists have developed efficient vaccines andpromisingtherapeutic interv...
The SARS-CoV-2 pandemic has been characterised by the regular emergence of genomic variants. With natural and vaccine-induced population immunity at high levels, evolutionary pressure favours variants better able to evade SARS-CoV-2 neutralising antibodies. The Omicron variant (first detected in Novemb...
有研究对几种不同血清型的编码SARS-CoV-2 S 蛋白的Ad 进行测试,发现其对COVID-19 有效。 Ad 是无包膜的双链DNA 病毒,其二十面体衣壳直径在80 -100 nm之间,可感染多种细胞,包括上皮细胞和内皮细胞以及肝细胞和成肌细胞等。Ad 在20 世纪90 年代成为第一个用于治疗基因递送的体内基因表达载体,用于治疗α-...
SARSCoV-2在过去 2 年中已在全球范围内传播,造成数亿例确诊感染和数百万人死亡。 SARSCoV-2 病毒刺突蛋白的受体结合域 (RBD) 启动与宿主受体血管紧张素转换酶 2 (ACE2)的结合,并作为病毒-细胞膜融合的初始重要步骤。针对 RBD 的中和抗体已显示出治疗和临床价。然而,已广泛观察到 SARS-CoV-2 变体对抗体和血...
Fig. 1: Structures of the SARS-CoV-2 B.1.351 neutralizing antibodies. aSummary of the antibodies characterized in this study. Antibody classes are assigned basically as described previously.9Specifically, class 1 and 2 antibodies directly block ACE2, whereas class 3 and 4 do not; class 1 and...
Open reading frame 8 (ORF8) protein is one of the most evolving accessory proteins in severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), the causative agent of coronavirus disease 2019 (COVID-19). It was previously reported that the ORF8 protein inhibits presentation of viral antige...
The article discusses the worldwide infections caused by variants of the severe acute respiratory syndrome coronavirus 2 (SARS-Cov-2) and the mutated Omicron lineage and their global surveillance as of June 2024. Topics covered include the use of scientific data from genomic sequencing to u...
