Today, no treatment is approved against EIAV, contrary to HIV-1, manageable through antiretroviral therapy, known as HAART (highly active antiretroviral therapy) or cART (combination antiretroviral therapy). No information about the efficacy of antiretroviral drugs against EIAV is available in the literature. This study evaluates the <em>in vitro</em> antiviral effect of eighteen FDA-approved antiretroviral compounds from different drug families, in an equine cells <em>in vitro</em> infection model with EIAV reference strain. Equine dermal cells, as well as equine peripheral blood mononuclear cells were treated with non-cytotoxic drug concentrations and infected with EIAV. Relative virus release in culture supernatants was assessed through relative quantification of viral RNA via RTqPCR and viral DNA comprising proviral integration in the cell genome was assessed through qPCR of infected cells, both after nucleic acid extractions. Out of eighteen tested drugs, thirteen showed a significant antiviral effect against EIAV <em>in vitro</em>, an interesting discovery showing the similarities between HIV-1 and EIAV and opening a possibility to treat equine infectious anemia to avoid the disease spread.</div></div>","PeriodicalId":23483,"journal":{"name":"Virus research","volume":"350 ","pages":"Article 199503"},"PeriodicalIF":2.5,"publicationDate":"2024-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC11699113/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142755710","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Circular RNAs (circRNAs), a closed-loop molecular structure, have been reported to be involved in virus infectious diseases. However, their roles and mechanisms in CVB5 infection remain largely unknown. In this study, we identify that CircPTPN11 is significantly upregulated following CVB5 infection in RD cells. Characteristic analysis reveals that the expression of CircPTPN11 is both time- and dose-dependent upon CVB5 infection and is specific to intestinal tissue. Moreover, CircPTPN11 inhibits CVB5 replication by activating IRF3 in the type-I interferon (IFN-I) pathway. Further underneath mechanism shows that CircPTPN11 indirectly regulates CVB5 replication by sponging miR-152-3p, and miR-152-3p influences CVB5 replication by interacting with the gene coding for signal regulatory protein alpha (SIRPA). In conclusion, this study suggests that CircPTPN11 targets SIRPA by sponging miR-152-3p, thereby inhibiting the replication and proliferation of CVB5.
