Abstract SARS-CoV-2 Omicron BA.2.75 subvariant has evolved to a series of progeny variants carrying several additional mutations in the receptor-binding domain (RBD). Here, we investigated whether and how these single mutations based on BA.2.75 affect the neutralization of currently available anti-RBD monoclonal antibodies (mAbs) with well-defined structural information. Approximately 34% of mAbs maintained effective neutralizing activities against BA.2.75, consistent with those against BA.2, BA.4/5, and BA.2.12.1. Single additional R346T, K356T, L452R, or F486S mutations further facilitated BA.2.75-related progeny variants to escape from broadly neutralizing antibodies (bnAbs) at different degree. Only LY-CoV1404 (bebtelovimab) displayed a first-class neutralization potency and breadth against all tested Omicron subvariants. Overall, these data make a clear connection between virus escape and antibody recognizing antigenic epitopes, which facilitate to develop next-generation universal bnAbs against emerging SARS-CoV-2 variants.

Mutation Information
Note
Basic Characteristics of Mutations
  • Mutation Site: The specific location in a gene or protein sequence where a change occurs.
  • Mutation Level: The level at which a mutation occurs, including the nucleotide or amino acid level.
  • Mutation Type: The nature of the mutation, such as missense mutation, nonsense mutation, synonymous mutation, etc.
  • Gene/Protein/Region: Refers to the specific region of the virus where the mutation occurs. Including viral genes, viral proteins, or a specific viral genome region. If the article does not specifically indicate the relationship between the mutation and its correspondence, the main
  • Gene/Protein/Region studied in the article is marked.
  • Genotype/Subtype: Refers to the viral genotype or subtype where the mutation occurs. If the article does not specifically indicate the relationship between the mutation and its correspondence, the main Genotype/Subtype studied in the article is marked.
  • Viral Reference: Refers to the standard virus strain used to compare and analyze viral sequences.
Functional Impact and Mechanisms
  • Disease: An abnormal physiological state with specific symptoms and signs caused by viral infection.
  • Immune: The article focuses on the study of mutations and immune.
  • Target Gene: Host genes that viral mutations may affect.
Clinical and Epidemiological Correlations
