Abstract A persistent infection model was established after human hepatoma cells infected by Japanese encephalitis viruses were subcultured for several times. Viral titers of mutant viruses in persistently infected cells were examined by plaque methods using BHK cells. Nucleotides of the E coding region of two wild and two mutant viruses were amplified by RT-PCR. PCR products were sequenced by ABI-PRSM 310 sequencing system. Compared to JaGAr-01 wild strains, four amino acids were replaced (E61Tyr --> Asp, E219His --> Tyr, E384Val --> Glu, E418Pro --> Ala) in the E sequence of JaGAr-01 persistently-infected mutant strains. Eleven amino acid replacement (E51Arg --> Ser, E61Tyr --> Asp, E83Lys --> Glu, E123Ser --> Arg, E209Arg --> Lys, E227Pro --> Ser, E276Asp --> Ser, E290Arg --> Lys, E387Lys --> Arg, E418Leu --> Pro, E454Arg --> Gly) was also noted when we compared the E sequence between persistently infected Nakayama and its wild strains. A lot of similarities of amino acid sequence between mutant strains JaGAr-01 and Nakayama were also noted. It was concluded that geno-variation existed in E region of mutant viruses and the mutant protein encoded by E region, especially the mutation of E61 (Tyr --> Asp) may contribute to the maintenance of the persistent infection of Japanese encephalitis virus.

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.
