The Fukushima/O695/2019 (O695) HPIV3 clinical isolate has a G-to-A substitution at the last position of five serial G residues in the RNA editing site. This study evaluates the effects of this substitution in the RNA editing site on the biological character of HPIV3. Our results show that O695 has slightly reduced viral replication compared with viruses with an intact RNA editing site. The number of G nucleotides inserted into the RNA editing site in HPIV3 isolates with an intact RNA editing site was 5 or fewer in most cases, giving a total of 10 serial G bases (5 + 5). In contrast, the number of G nucleotides inserted into the RNA editing site in O695 showed an atypical pattern, with six or fewer in most cases. This resulted in a total of 10 (4 + 6), suggesting the additional insertion of one more nongenomic G to the mRNA of the P gene of O695 compared with viruses carrying no mutations in the RNA editing site. Phylogenetic analysis reveals that mutations in the RNA editing site occur sporadically with various mutation patterns, suggesting that these mutations are routinely selected for during the life cycle of HPIV3.</p>\u0000 </div>","PeriodicalId":18679,"journal":{"name":"Microbiology and Immunology","volume":"69 4","pages":"220-228"},"PeriodicalIF":1.9,"publicationDate":"2025-02-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143399202","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The salivary glands play an essential role in homeostasis in the oral cavity. Here, we investigated the effects of periodontal inflammation on salivary gland function and the oral microbiome. In experimental periodontitis model mice, an increase in IgA⁺ cells in the salivary glands were observed 1 week after treatment. Alteration of the oral microbiome was also induced in this model. Gene expression analysis of the salivary glands showed changes in the expression of genes related to B-cell maturation and plasma cell differentiation and an increase in the expression of genes related to macrophage activation upon experimental periodontitis induction. Furthermore, the relationship between disruption of oral microflora and salivary gland function was examined using a cohousing model in which experimental periodontitis model mice and untreated mice were reared in the same cage. We found that cohoused normal mice underwent alteration of the oral microbiome, with increases in IgA⁺ cells and macrophages in the salivary glands. In summary, our results suggest that, in the oral cavity, there is a close link between oral bacterial flora and immune cells in the salivary glands. Our results also show that localized inflammation disrupts the homeostasis in the oral cavity, inducing pathological conditions such as dysbiosis.
