Azim Ansari, Carolin Mogler, John McLauchlan, Xavier Forns, Sofía Pérez-del-Pulgar, Volker Lohmann Nature Communications, 2025 Hepatitis C virus (HCV) exists as a heterogenous quasispecies, but the phenotypic consequences of viral variability are widely unexplored. Here we identify a replication enhancing domain (ReED) in non-structural protein 5A conferring high replication fitness to clinical isolates. Accumulation of mutations in the ReED mediates high genome replication capacity. In a cohort of liver transplant patients, high replicator variants are exclusively found in individuals with severe disease outcome, suggesting that high viral replication fitness is associated with increased viral pathogenesis. Analysis of large sequence cohorts reveals that overall only 10% of viral genomes show genetic signatures of high replicators, which are enriched in recipients of liver transplantations, patients developing hepatocellular carcinoma and in HIV coinfected individuals. Overall, our data suggests that low replication fitness is a hallmark of HCV, contributing to establishment of persistence, whereas high replicators appear to have an advantage under conditions of immune suppression, thereby enforcing pathogenesis.

Gehring, Mala K. Maini, Xavier Forns, Sofía Pérez‐del‐Pulgar Liver International, 2025 Background and AimPD‐1‐expressing T cells within the HBV‐infected liver constitute a target of novel immunotherapeutics. Our aim was to investigate the impact of viral suppression on PD‐1 expression on intrahepatic versus circulating lymphocyte populations from chronic hepatitis B (CHB) patients.MethodsTwenty‐two CHB patients, nine of them on nucleos(t)ide analogues (NUCs), had paired blood, liver fine needle aspirations (FNAs) and biopsies. A subset had a follow‐up FNA after treatment initiation (n = 4) or discontinuation (n = 4). Intrahepatic (iHBV‐DNA and cccDNA) and serum (HBV‐DNA, HBsAg, HBcrAg and cirB‐RNA) viral markers were quantified. Flow cytometry was used for immunophenotyping PBMCs and intrahepatic lymphocytes. An independent liver FNA scRNAseq dataset was used to consolidate our results.ResultsPD‐1 expression on tissue‐resident memory CD8 T cells (TRM) correlated with both iHBV‐DNA and cccDNA, as well as surrogate markers of cccDNA transcriptional activity (cirB‐RNA and HBcrAg) in CHB patients with mild hepatitis. These associations were not reflected in circulating T cells. PD‐1 expression intensity on CD8 TRM was lower in NUC‐treated than in naive patients, changes that were again not detectable in the circulation. Longitudinal analysis showed that viral load rebound induced by NUC discontinuation had the potential to drive re‐expression of high levels of PD‐1 on CD8 TRM. Conversely, therapy initiation and subsequent viral suppression reversed these changes. scRNAseq results further extended the profiling of these PD‐1 + CD8 TRM, showing a phenotype consistent with bystander activation in response to subclinical liver damage.ConclusionsIntrahepatic viral markers correlate with PD‐1 expression on global liver‐resident T cells of CHB patients with mild hepatitis, with a reduction after prolonged NUC therapy and re‐expression following treatment withdrawal.

HBcrAg and cirB-RNA Do Not Predict Clinical and Virological Outcomes in Patients With HBeAg-Negative Chronic Infection Sara Battistella, Thais Leonel, Anna Pocurull, Sergio Rodrìguez‐Tajes, Maria Saez‐Palma, Ariadna Rando‐Segura, Zoe Mariño, David Tabernero, Juan Carlos Hurtado, Maria Francesca Cortese, Sofía Pérez‐del‐Pulgar, Sabela Lens, Xavier Forns Liver International, 2025 Background & AimsPredicting clinical and virological outcomes in HBeAg‐negative (HBeAg‐neg) chronic infection often requires long‐term monitoring. Our study explored whether a single measurement of quantitative HBsAg (qHBsAg), HBV core‐related antigen (HBcrAg), and circulating HBV RNA (cirB‐RNA) can define the natural course of untreated HBeAg‐neg chronic infection patients.MethodsTo this aim, we included 128 naïve HBeAg‐neg chronic infection patients, stratified according to qHBsAg levels in: (1) 10–1000 IU/mL, (2) 1000–10 000 IU/mL, and (3) > 10 000 IU/mL.ResultsHBcrAg and cirB‐RNA were detected in 27% and 19% of patients with qHBsAg > 1000 IU/mL but rarely detected in patients with qHBsAg < 1000 IU/mL. After a median follow‐up of 5.1 years, 9.4% of patients lost HBsAg, and 8.5% experienced an increase in HBV DNA > 2000 IU/mL. qHBsAg < 1000 IU/mL was the only factor independently associated with functional cure.ConclusionsIn untreated HBeAg‐neg chronic infection patients, single‐point cirB‐RNA and HBcrAg do not offer additional predictive value over qHBsAg < 1000 IU/mL for spontaneous HBsAg loss.
Tracking B cell immunity during perturbation of hepatitis B infection induced by treatment withdrawal Sabela Lens, Alice R Burton, Jessica Davies, Maelle Locatelli, Mireia García-López, Anna Pocurull, Anna Jeffery-Smith, Nikolai Novikov, Simon P Fletcher, Xavier Forns, Sofía Pérez-del-Pulgar, Mala K Maini Gut, 2025 Background Withdrawal of prolonged nucleos(t)ide analogue (NA) treatment results in hepatitis B surface antigen (HBsAg) loss in some subjects with chronic hepatitis B (CHB), potentially revealing immune correlates of functional cure. Objective We investigated whether baseline or longitudinal changes in humoral immunity correlated with outcome of discontinuing prolonged NA treatment. Design Global memory B cells (MBC) and T follicular helper cells (Tfh) were analysed by flow cytometry. HBs (small surface)/HBc (core)-MBC were quantified by ex-vivo bait staining and function assessed by cultured ELISpots (enzyme-linked immunosorbent spots). Immune parameters assessed at end-of-treatment (EOT), 12 and 48 weeks after treatment withdrawal (and at 4–8 years in a subset) were correlated with intrahepatic and longitudinal serum viral markers and alanine transaminase (ALT). Results Individuals on prolonged NA had comparable frequencies of HBc-MBC and HBs-MBC, although the latter were PD-1 hi and functionally defective. Following treatment withdrawal, increases in class-switched HBc-MBC were frequently temporally linked with hepatic flares. Subjects achieving HBsAg loss had an increase in activated global MBC detectable at EOT that become more marked by week 48, accompanied by significant increases in plasmablasts. HBs-MBC in those with HBsAg loss showed significant reductions in PD-1, trends to increased activation (CD71) and function and a more robust correlation with Tfh, compared with HBsAg persistence. MBC changes were maintained 4–8 years after HBsAg seroconversion. Conclusion Differences in global and HBs-specific B cell immunity associate with HBsAg loss, whereas HBc-MBC temporally associates with flares, following withdrawal of prolonged NA treatment. Our results underscore the need to further explore the potential of B cell targets for monitoring and enhancing HBV functional cure in larger cohorts.
Detection of Hepatitis C Virus Infection from Patient Sera in Cell Culture Using Semi-Automated Image Analysis Noemi Schäfer, Paul Rothhaar, Christian Heuss, Christoph Neumann-Haefelin, Robert Thimme, Julia Dietz, Christoph Sarrazin, Paul Schnitzler, Uta Merle, Sofía Pérez-del-Pulgar, Vibor Laketa, Volker Lohmann Viruses, 2024 The study of hepatitis C virus (HCV) replication in cell culture is mainly based on cloned viral isolates requiring adaptation for efficient replication in Huh7 hepatoma cells. The analysis of wild-type (WT) isolates was enabled by the expression of SEC14L2 and by inhibitors targeting deleterious host factors. Here, we aimed to optimize cell culture models to allow infection with HCV from patient sera. We used Huh7-Lunet cells ectopically expressing SEC14L2, CD81, and a GFP reporter with nuclear translocation upon cleavage by the HCV protease to study HCV replication, combined with a drug-based regimen for stimulation of non-modified wild-type isolates. RT-qPCR-based quantification of HCV infections using patient sera suffered from a high background in the daclatasvir-treated controls. We therefore established an automated image analysis pipeline based on imaging of whole wells and iterative training of a machine learning tool, using nuclear GFP localization as a readout for HCV infection. Upon visual validation of hits assigned by the automated image analysis, the method revealed no background in daclatasvir-treated samples. Thereby, infection events were found for 15 of 34 high titer HCV genotype (gt) 1b sera, revealing a significant correlation between serum titer and successful infection. We further show that transfection of viral RNA extracted from sera can be used in this model as well, albeit with so far limited efficiency. Overall, we generated a robust serum infection assay for gt1b isolates using semi-automated image analysis, which was superior to conventional RT-qPCR-based quantification of viral genomes.
Hepatitis C virus-induced differential transcriptional traits in host cells after persistent infection elimination by direct-acting antivirals in cell culture Victoria Castro, Gema Calvo, Juan Carlos Oliveros, Sofía Pérez‐del‐Pulgar, Pablo Gastaminza Journal of Medical Virology, 2024 Chronic hepatitis C virus infection (HCV) causes liver inflammation and fibrosis, leading to the development of severe liver disease, such as cirrhosis or hepatocellular carcinoma (HCC). Approval of direct‐acting antiviral drug combinations has revolutionized chronic HCV therapy, with virus eradication in >98% of the treated patients. The efficacy of these treatments is such that it is formally possible for cured patients to carry formerly infected cells that display irreversible transcriptional alterations directly caused by chronic HCV Infection. Combining differential transcriptomes from two different persistent infection models, we observed a major reversion of infection‐related transcripts after complete infection elimination. However, a small number of transcripts were abnormally expressed in formerly infected cells. Comparison of the results obtained in proliferating and growth‐arrested cell culture models suggest that permanent transcriptional alterations may be established by several mechanisms. Interestingly, some of these alterations were also observed in the liver biopsies of virologically cured patients. Overall, our data suggest a direct and permanent impact of persistent HCV infection on the host cell transcriptome even after virus elimination, possibly contributing to the development of HCC.
miRNA Expression and HCC Occurrence in HCV Cirrhotic Patients Treated with Direct Acting Antivirals Antonietta Romano, Alessandra Brocca, Zoe Mariño, Sofía Pérez-del-Pulgar, Sabela Lens, Loreto Boix, María Reig, Jordi Bruix, Giulio Ceolotto, Valeria Calvino, Gianluca Zilio, Paula Piñero Romero, Ranka Vukotic, Valeria Guarneri, Pietro Andreone, Saverio Giuseppe Parisi, Francesco Paolo Russo, Salvatore Piano, Umberto Cillo, Paolo Angeli Livers, 2024 Background: The risk of hepatocarcinoma in HCV cirrhotic patient responders after treatment with DAAs decrease, but HCC still occurs. A correlation between specific miRNAs and the development of hepatocarcinoma have been highlighted. Aim: To investigate miRNA expression in HCV-infected cirrhotic patients treated with DAAs, regarding whether or not they developed HCC at follow-up. Methods: A total of 73 outpatients with HCV-related cirrhosis treated with DAAs were enrolled, 28 of which had HCC. Samples were collected at the start and at the end of treatment. In the screening phase, 172 miRNAs were analyzed at baseline. Differentially expressed miRNAs were validated in the entire cohort. Results: In the validation phase, at baseline and in patients treated for 12 weeks, miR-28-5p was confirmed to be more highly expressed in the HCC group compared to the non-HCC group. In all of the patients treated for 12 weeks, at end of the treatment we found a significant downregulation in miR-132-3p, miR-133b-3p, miR-221-3p and miR-324-3p. In the HCC group, miR-28-5p was significantly downregulated after DAA therapy as well as in HCC patients treated for 24 weeks. Conclusion: In the HCC group, miR28-5p was differently expressed both at baseline and at the end of therapy with DAAs. This difference in expression should suggest its involvement in HCC development.
