Methods: With the aid of a rat ELISA kit, the we identified specific IgG antibodies against the Rabies virus. The presence of SEOV and HEV was determined using an SYBR Green-based real-time PCR assay. Results: 1% of the R. norvegicus carried the rabies virus. HEV was associated with R. norvegicus obtained from the south of Tehran with the highest frequency (35%). 12% of tests for SEOV were positive. Conclusion: The findings highlight the importance of putting in place rodent control programs and avoiding interaction with rodent populations in urban settings.","PeriodicalId":12505,"journal":{"name":"Future Virology","volume":" ","pages":""},"PeriodicalIF":3.1,"publicationDate":"2023-09-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"42547487","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}

Methods: Huh7 cells were transfected with HCV (JFH1 or Jc1) or sub-genomic replicons and expression of pro-fibrotic cytokines determined by qPCR. Media from infected cells was transferred onto LX2 cells or primary rat stellate cells and expression of pro-fibrotic genes measured by qPCR. Results: Replication competent HCV, but not sub-genomic replicons, induced expression of TGF-β1 and CTGF. Supernatant from infected cells induced α-SMA and COL1A1 expression and stellate cell migration, confirming functional activation. Conclusion: Infected cells produce pro-fibrogenic cytokines TGF-β1 and CTGF and activate stellate cells. This mechanism could be targeted to prevent or treat HCV-induced fibrosis.","PeriodicalId":12505,"journal":{"name":"Future Virology","volume":"20 1","pages":""},"PeriodicalIF":3.1,"publicationDate":"2023-09-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"68215671","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}

Cytopathic assay after DENV infection was performed in vitro to check the effect of UEP and its constituents. Histopathology analysis revealed DENV-mediated fibrosis and the effect of UEP. qRT-PCR and gelatin zymography showed levels of fibrosis-causing genes. Results: UEP showed low cytotoxicity and maximum potential in mitigating DENV-mediated fibrosis in vivo via regulation of fibrosis biomarkers TGF-β, MMP-1, MMP-9, TIMP-1 and IFNs.

Results: Two specific modules were most related to rotavirus infection. The analysis of differentially expressed genes (DEGs) disclosed 393 DEGs between normal and infected individuals. Eighteen novel genes were shared between the modules.

Meanwhile, much evidence has shown that m6A methylation regulates the life cycle of viruses and inhibits or promotes the development of various viruses. However, the mechanism of m6A methylation in virus-associated tumors has not been fully elucidated. This review highlights the role of m6A modification in various viruses to help establish new approaches for treating related diseases.","PeriodicalId":12505,"journal":{"name":"Future Virology","volume":" ","pages":""},"PeriodicalIF":3.1,"publicationDate":"2023-09-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"43203831","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}

Results: Compound 2 showed antiviral activity against CHIKV 181-25 in BHK-21 and Vero cells. Also, this compound presented a higher activity against CHIKV BRA/RJ/18 in Vero cells, like compound 1. Compound 2 exhibited virucidal activity and inhibited virus entry while compound 1 inhibited virus release. Molecular docking suggested that these derivatives inhibit nsP1 protein while compound 1 may also target capsid protein.
