Domain III (DIII) of the envelope protein mediates early virus:cell interactions and is target of potent neutralizing antibodies. Little data is available on the dynamic of IgG subclasses in anti-DIII response elicited during viral infection. Fifty-eight human sera were used to characterize the IgG subclass profile of the anti-DIII antibody response in terms of abundance and serotype-specificity. Immunodominant epitopes were also determined using 70 Ala-mutants of a recombinant DIII protein that spans residues with more than 15% of the exposed area in the virion. IgG1 and IgG3 were found as the subclasses that react to control primary infections while a significant response was detected for all IgG subclasses in response to secondary infections. Anti-DIII IgG1 exhibits a distinctive pattern of serotype-specificity with respect to the other IgG subclasses in the recognition of recombinant DIII proteins corresponding to the four DENV serotypes. The dominant epitope of IgG1 is located in the FG-loop, which is characterized by high variability in its amino acid sequence. In contrast, the dominant epitopes of IgG2, IgG3, and IgG4 were defined as regions enriched in complex- and subcomplex conserved residues such as the A-strand and the AB-loop of DIII. IgG1 plays a prominent role in neutralizing circulating DENV during infection. A balanced and timely response of the different IgG subclasses is critical in the evolution of dengue disease.</p>\u0000 </div>","PeriodicalId":16354,"journal":{"name":"Journal of Medical Virology","volume":"97 3","pages":""},"PeriodicalIF":6.8,"publicationDate":"2025-02-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143475649","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Phylogenetical and genetic analyses of the data set revealed that four genotypes were co-circulating in Shandong province. C3 genotype was the most common genotype in each year with lower genetic divergence. 298 amino acid substitutions were detected in the four proteins of SFTSV, but only two substitutions (Arg624Lys and Arg962Ser) had been proven to have potential impacts on biological functions. In addition, one reassortment strain (C3/C4/C4 for L, M and S segments) and three recombinant strains were identified. Analysis of selection pressure at the level of amino acid substitutions indicated genes within the four ORFs of SFTSV were all subjected to negative selection.
