Abstract Chikungunya virus (CHIKV) is a mosquito-transmitted alphavirus responsible for the first autochthonous Italian outbreak in 2007. A226V mutation in E1 has been associated with enhanced replication in A. albopictus vector. Possible involvement of this mutation in enhanced infection capability in primate cells and sensitivity to exogenous interferon (IFN)-a was investigated. No significant differences were observed between the two isolates in terms of replication kinetic, virus yield and cytopathic effect (CPE). Interestingly, the A226V-carrying strain was more susceptible to the antiviral action of recombinant IFN-a. The interplay between A226V mutation and innate defence mechanisms needs further investigation.

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.
