2023年5月7日 · 研究者首先 利用假病毒系统评估B.1.1.529对三针国产疫苗免疫者血清中和活性的敏感性，发现接种三针疫苗人群的血清对突变株的中和能力相比原始毒株有大幅下降，提示变异病毒具备免疫逃逸能力。然而，变异株病毒仍然对重组可溶性人ACE2 ...
Omicron (B.1.1.529) is a variant of SARS-CoV-2 first reported to the World Health Organization (WHO) by the Network for Genomics Surveillance in South Africa on 24 November 2021.[10][11] It was first detected in Botswana and has spread to become the predominant variant in circulation around the world.[12] Following the original B.1.1.529 ...
2022年1月24日 · The latest severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) variant Omicron (B.1.1.529) has ushered panic responses around the world due to its contagious and vaccine escape mutations. The essential infectivity and antibody resistance of the SARS-CoV-2 variant are determined by its mutations on the spike (S) protein receptor-binding ...
2022年3月24日 · B.1.1.529 mutations present in the spike gene resulted in three deletions of two, three, and one amino acids, a single insertion of three amino acids, and 30 amino acid substitutions in the spike ectodomain (fig. S2A). As expected from the ~3% variation in the B ...
2022年10月1日 · They discovered 45 genetic mutations in Omicron since it diverged from the B.1.1 lineage. The Omicron S-protein sequence was shown to be subjected to more positive selection than any other SARS-CoV-2 variant known to develop consistently in human hosts, implying the likelihood of host-jumping [49] .
