Abstract Most street rabies virus glycoproteins (G proteins) possess two N-glycosylation sites, at Asn(37) and Asn(319), whereas an additional N-glycosylation site is present in several fixed (laboratory-adapted) rabies virus strains at Asn(247), which suggests that the N-glycosylation addition may be a marker of fixed viruses. In this study, we successfully cloned two street virus strain 1088 variants, N5B#15 and N5B#10-28, in which the G proteins had an additional N-glycan at position 247, and we examined whether these variants were characterized by cell culture adaptation and attenuation after intramuscular inoculation as fixed viruses. N5B#15 had four mutations, i.e., S148P and D247N in the G protein, and T137A and N2046S in the large (L) protein. N5B#10-28 had an additional mutation in the G protein, R196I. Compared with the parental 1088 virus, both variants exhibited highly efficient replication in mouse neuroblastoma-derived NA cells and reduced pathogenicity in adult mice when inoculated intramuscularly, but not intracerebrally. However, this attenuation was not attributable to the induction of strong immune responses.

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.
