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
  • Clinical Information: The study is a clinical or epidemiological study and provides basic information about the population.
  • Treatment: The study mentioned a certain treatment method, such as drug resistance caused by mutations. If the study does not specifically indicate the relationship between mutations and their correspondence treatment, the main treatment studied in the article is marked.
