Although the construction of a wild-type HBoV1 infectious clone has been reported, generating HBoV1 infectious clone carrying foreign reporter genes with suitable insertion sites in its genome while retaining replicative ability remains challenging. Here, HBoV1 infectious clones harboring the 11-amino-acid HiBiT tag at five distinct insertion sites were constructed and evaluated. Only the recombinant HBoV1 carrying the HiBiT tag in the N-terminus of the NS1 protein (HBoV1-HiBiT<sub>NS1</sub>) displayed comparable characteristics to wild-type HBoV1 as determined via the analysis of viral DNA copy number, NanoLuc activity, viral protein expression, and the formation of replication intermediates. Notably, the replication kinetics of HBoV1-HiBiT<sub>NS1</sub> could be examined by monitoring NanoLuc activity, which was noted to be correlated with the viral DNA level. Additionally, we successfully applied HiBiT-tagged HBoV1 for the evaluation of antiviral drug activity and identified ivermectin (EC50 = 2.27 μM) as a potent anti-HBoV1 replication drug.

We and others have previously demonstrated that Naf1 restricts HIV-1 infection of T-lymphocytes. Myeloid cells are targets for HIV infection, but Naf1 expression in myeloid cells and whether it also regulates HIV infection in these cells are not yet identified. In this study, we found that Naf1 had a higher expression in CD14<sup>+</sup> monocytes than in monocyte-derived dendritic cells (MDDCs), and its expression in both types of cells could be induced by HIV-1 gp120 glycoproteins or viral particles. Importantly, the expression of Naf1 restricted HIV-1 infection in monocytes and MDDCs. Functional investigation showed that both the constitutive and the induced expression of Naf1 inhibited NF-κB signaling in MDDCs and reduced the basal level or LPS (Lipopolysaccharide)-stimulated production of cytokines. Moreover, Naf1 reduced the expression of ICAM-1 (intercellular cell adhesion molecule-1) on MDDCs and compromised their capacity to prime the activation of resting CD4<sup>+</sup> T cells in co-culture. In light of the essential role of NF-κB signaling for HIV-1 transcription, Naf1-mediated inhibition of NF-κB signaling may hinder a robust viral replication in MDDCs and help maintain viral persistence. Furthermore, virus-induced Naf1 expression in MDDCs may diminish the cross-talk between DC (dendritic cell) and T cells, hence suppressing the activation of antiviral immune responses. Taken together, we identified the new function of Naf1 in myeloid cells. Those findings may facilitate the understanding for the host restriction of HIV-1 infection in myeloid cells.</div></div>","PeriodicalId":23654,"journal":{"name":"Virologica Sinica","volume":"40 2","pages":"Pages 217-224"},"PeriodicalIF":5.5,"publicationDate":"2025-04-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143732054","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}

In this study, SFTS-relative key targets were predicted via gene ontology (GO) analysis and kyoto encyclopedia of genes and genomes (KEGG) enrichment analysis. Molecular docking was then used to select stable binders. Molecules matched TCMs were identified, and a new prescription, Qingqi Guxue decoction (QQGX), was formulated to clear heat and nourish blood, with a resulting drug composition network. We explored the optimal drug proportion for QQGX. Through an in-depth study of molecular mechanisms, we found that QQGX induces S phase arrest by promoting the degradation of cyclin A2 (CCNA2) and cyclin-dependent kinase 2 (CDK2), thereby inhibiting SFTSV replication. Finally, we verified the effectiveness and safety of QQGX based on the mouse liver bile duct organoid model infected with SFTSV.

Interestingly, FZJDD was found to block the binding of SARS-CoV-2 Spike protein with the receptor ACE2 and inhibit the activity of SARS-CoV-2 3CLpro. Moreover, FZJDD can regulate the TNF and the MAPK signaling pathway to inhibit the inflammatory response and alleviate the “cytokine storm”.
