However, there is no consensus in the literature on the structure of the upper part of this domain. Currently, the model proposed by Keane et al. in 2015 is dominant, although the question of whether it is general structure or specific to the experimental HIV-1 genome NL4–3 of subtype B remains open. To clarify this issue, we conducted large-scale <em>in silico</em> studies on the secondary structure of the domain closed by the U5-AUG duplex in 2754 HIV-1 genomes of different subtypes. Our investigation showed that the proportion of HIV-1 genomes in which the structure of the domain under study is similar to that in Keane et al. model is low. It forms mainly in HIV-1 genomes of subtype B with the frequency of 3.8 % in the optimal foldings or foldings with the energy increment of the lowest change in free energy (ΔΔG)&lt;1.0 kcal/mol. In particular, certain base changes in common SD hairpin or base changes stabilizing Psi hairpin contribute to the formation of this domain variant. The dominant structure of the domain closed by the U5-AUG duplex is similar to that in Wilkinson et al. model (2008) but with the alternative SD hairpin. We found also new variants of this domain, which occur in foldings with ΔΔG&lt;1.0 kcal/mol and may co-exist with dominant structure. However, it is possible that the variants of the domain closed by the U5-AUG duplex similar to Wilkinson et al. or Keane et al. models are formed only in the early stages of HIV-1 replication, while in the late stage (in the presence of nucleocapsid protein) the domain adopts structure similar to that in Sakuragi et al. (2012) model and the initiation of the reverse transcription occurs just in this structure. Extreme conservation of GACGC-GCGUC duplex, proposed in Sakuragi et al. model, supports this assumption.</div></div>","PeriodicalId":23483,"journal":{"name":"Virus research","volume":"357 ","pages":"Article 199581"},"PeriodicalIF":2.5,"publicationDate":"2025-05-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144095156","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}

Accordingly, this study aimed to estimate the global co-occurrence rate of chronic HCV infection and SS. In this systematic review and meta-analysis, a comprehensive search for relevant studies was conducted in PubMed, Scopus, ISI Web of Science, and Google Scholar databases up to June 2024. Data from eligible studies were meticulously extracted and statistically analyzed using Comprehensive Meta-Analysis Software. The pooled prevalence of co-occurrence of HCV and SS was calculated using incidence rates with 95 % confidence intervals (CIs), and the association of chronic HCV infection with the development of SS was assessed via odds ratios (ORs) with 95 % <em>CIs</em>. Analysis of the articles retrieved from the databases showed 24 studies were considered eligible. The pooled estimate for the co-occurrence of HCV and SS was approximately 16.6 % (95 % CI: 8.8–28.9). Moreover, the results indicated that chronic HCV infection significantly increased the risk of developing SS (OR: 2.76; 95 % CI: 1.35–5.63).

Serum samples were analyzed using nested PCR and sequencing of the 5′-UTR region to detect HPgV-1 RNA and determine genotypes. The prevalence of HPgV-1 was significantly higher in HD patients (13.6 %) compared to healthy controls (0.6 %). Among HPgV-1-positive HD patients, only genotype 2a was identified. Co-infections were notable, with 11.8 % of HPgV-1-positive patients also infected with HCV (predominantly genotype 3a), 3.0 % with HBV, and 11.7 % with HIV. Interestingly, HCV co-infected patients exhibited lower liver enzyme levels, while those co-infected with HIV had significantly higher CD4+ <em>T</em> cell counts (605.2 ± 198.7 vs. 412.3 ± 156.8 cells/mm³, <em>P</em> &lt; 0.001), suggesting potential immunomodulatory effects of HPgV-1. Additionally, factors such as prolonged dialysis duration, elevated urea levels, and older age were significantly associated with HPgV-1 positivity. These findings underscore HD as a major risk factor for HPgV-1 transmission, likely exacerbated by hospital-acquired practices in dialysis units. The observed associations between HPgV-1 and improved clinical parameters in co-infected individuals highlight its complex role in viral pathogenesis, warranting further investigation into its underlying mechanisms.

Previous studies have shown that JNK kinase is essential in promoting inflammatory responses during viral infections. In this study, we demonstrated that JNK kinase could regulate the IAV-induced cytokine storms by affecting the expression of pro-inflammatory and anti-inflammatory factors. Further studies revealed that inhibition of JNK kinase activity significantly downregulated the expression of the inflammatory amplifier TREM1. Besides, TREM1 knockdown could significantly inhibit the expression of pro-inflammatory factors. Furthermore, SP600125 is a specific inhibitor of JNK kinase. The results show that TREM1 overexpression reversed the effect of SP600125 treatment on the expression of pro-inflammatory factors.
