Full textSevere acute respiratory syndrome-related coronavirus 2 (SARS-CoV-2), a member of the Coronaviridae family, is responsible for coronavirus disease 2019 (COVID-19). Despite the availability of vaccines that helped end the COVID-19 health emergency, the viral circulation of SARS-CoV-2 remains, as well as research on the understanding of its pathophysiology, in particular the involvement and role of microRNAs (miRNAs) in this viral infection. miRNAs are small non-coding RNAs that regulate gene expression and are known to be involved in numerous cellular regulatory pathways. Recently, they have also been shown to be involved in SARS-CoV-2 infection. Such research would provide a better knowledge in this field and could be useful in the development of new diagnoses and clinical treatments against viral infection with SARS-CoV-2 or other infections of the same viral family. Thus, in this research project, we first characterized the cellular miRNA biomarkers of SARS-CoV-2 viral infection from patient nasopharyngeal swabs, which is the first diagnostic tool for this viral infection. In particular, our work has identified miRNAs associated with severe forms of COVID-19. These miRNA target genes involved in viral infections and antiviral and anti-inflammatory responses to viral infections. These potential antiviral and anti-inflammatory effects of miRNAs on SARS-CoV-2 viral infection could not be demonstrated in vitro in this study. Then, the hypothesis of deregulation of miRNA biogenesis by this viral infection was investigated. No under-expression of mRNAs of genes involved in the miRNA biogenesis pathway was found upon infection with SARS-CoV-2, either ex vivo or in vitro. Finally, based on a miRNA of clinical interest, we wanted to develop a possible clinical treatment against viral infection by SARS-CoV-2 or any other pathology through the delivery of miRNAs of interest, in this case antiviral. This would involve developing nanoparticles and nanomaterials coupled to miRNAs or other double-stranded messenger or non-messenger RNAs, to enable the latter to enter cells and thus restore basal expression of the genes involved in viral infection

Full textLassa virus causes a hemorrhagic fever endemic in West Africa and represents a threat for civilians. The pathogenesis and the immune responses associated with the disease are poorly understood. We followed pathological, virological and immunological parameters associated with fatal and non-fatal Lassa virus infection in the cynomolgus monkey. The clinical picture was characterized by depression, anorexia, weight loss and asthenia in survivors whereas the same symptoms were supported by fever, respiratory difficulties and epistaxis in animals infected with the lethal dose. Only fatalities have shown coagulation parameters dysfunction, rhabdomyolysis and an increase of renal function markers. We observed a different viral tropism in a function of the disease severity, with viral dissemination in organs that was more important and faster in fatalities, the appearance of numerous infectious particles number and more severe pathologic changes. Early and robust innate and adaptive immune response has been associated with the control of infection and recovery whereas fatal infections were characterized by a sepsis like inflammatory response, defective immune response as well as uncontrolled viral replication. This study sheds light on the pathogenesis of Lassa fever and reveals infection markers predictive of the disease outcome

Full textHepatocellular carcinoma (HCC) is a leading cause of death worldwide and the current treatments are unsatisfactory. One reason is the limited knowledge on the complexity and microenvironment of healthy and diseased liver. To address this gap, we have developed a single cell RNA sequencing (scRNA-seq) pipeline for primary human liver tissues. We have assembled an atlas of human liver cells and compared the scRNA-seq profile of normal liver and HCC. The atlas revealed an unknown heterogeneity within the main populations of liver cells, the transcriptomic zonation of endothelial cells and the existence of an epithelial progenitor in the adult liver capable of differentiating into both cholangiocytes and hepatocytes. ScRNA-seq analysis uncovered the marked cell heterogeneity of HCC, its microenvironment changes at single-cell level and the interactions between tumor cells and hepatitis B virus discovering previously unknown pathways and drivers of hepatocarcinogenesis

Full textEnteroviruses (EV) (Picornaviridae) are among the most common viruses infecting human beings worldwide. These viral agents are associated with a wide range of human pathologies, including upper respiratory but also lower respiratory tract infections resulting in bronchitis, pneumonia or bronchiolitis in adults or in infants. In the first study, we assessed the potential role of the respiratory picornaviruses as causative agents of bronchiolitis in 192 infants ≤36 months of age and hospitalized for acute bronchiolitis. The detection of common respiratory viruses (respiratory syncytial virus, influenza virus A and B, parainfluenza virus I, II, III, and adenovirus) was performed using classical immunofluorescence antigens and cell culture detection assays in nasopharyngeal aspirates whereas the detection of human metapneumovirus (HMPV) rhinoviruses and enteroviruses was performed by molecular techniques. A potential causative virus was detected in 72. 5 % of the 192 study infants. RSV (30%), rhinovirus (21%), enterovirus (9%), influenza virus A (6%) and human metapneumovirus (4%) were the most frequent causative agents detected. Rhinoviruses or enteroviruses were detected as the only evidence of respiratory viral tract infection in 57 (30%) of 192 infants, whereas rhinovirus or enterovirus occurred in mixed viral infection detected in 25 (13%) of 192 study cases (30 vs. 13%, p<10-3). Our data suggest that respiratory picornaviruses are one of the leading etiological causes of bronchiolitis in French infants. In the second part our investigations, we analysed 252 EV-related infection cases (median age, 5. 1 years) diagnosed among 11,509 consecutive children visiting emergency departments within a 7-year period in the North of France. EV strains were isolated from nasopharyngeal samples by viral cell culture, identified by seroneutralization assay and genetically compared by partial amplification and sequencing of the VP1 gene. The respiratory syndromes (79 (31%) of 252 EV infections) appeared as the second more frequent EV induced pediatric pathologies after meningitis (111 (44%) of 252 cases) (44 vs. 31%, P<10-3), contributing to lower respiratory tract infection (LRTI) in 43 (54%) of 79 EV respiratory infection cases. Bronchiolitis was the most frequent EV induced LRTI (34 (43%) of 79 cases, P<10-3) occurring more often in infants aged 1-12 months (P=0. 0002) with spring-fall seasonality. Viruses ECHO 11, 6 and 13 were the more frequently identified respiratory strains (24, 13 and 11%, respectively). The VP1 gene phylogenetic analysis showed the concomitant or successive circulation of genetically distinct EV respiratory strains (species A or B) during the same month or annual epidemic period. Our findings indicated that respiratory tract infections accounted for appreciatively 30% of EV-induced paediatric pathologies, contributing to LRTIs in 54% of these cases. Moreover, the concomitant or successive circulation of genetically distinct EV strains indicated the possibility of paediatric repeated respiratory infections within the same epidemic season. To identify the mechanisms that can regulate the development of airway mucosa inflammation during EV respiratory lower tract infection, we investigated the production of chemokines by EV-infected bronchial epithelial cells. Cultures of primary human small airway epithelial cell (SAEC) were infected by wild-type respiratory EV strains, demonstrating a replicative and productive infection by Coxsackievirus B5 and Echovirus 30 strains. Exposure of SAEC to gamma interferon (INF-γ), in combination with Coxsackievirus B5 and Echovirus 30 infection, induced a significant increase in RANTES production that was synergistic with respect to that obtained by EV-infection or INF-γ treatment alone. We observed that the replicative infection of the SAEC by Coxsackievirus B5 and Echovirus 30 wild-type viruses induced dose and time-dependent increases in mRNA and protein secretion for RANTES, MCP-1 and IL-8. The protein secretion of these chemokines appeared to be significantly increased at 48 or 72 hours post-infection in cultures treated by low-doses of INF-γ comparatively to mock-infected cells (P<0. 001), and was correlated to the viral replication activity. SAEC-derived chemokines exhibited a strong chemotactic activity for normal human blood eosinophils. Furthermore, we observed an EV productive infection in eosinophils, which specifically released significant levels of RANTES and MCP-1, 24 hours post-infection. Therefore, the inflammatory process in EV-induced bronchiolitis appears to be triggered by the infection of epithelial cells and further amplified via mechanisms driven by INF-γ and by the secretion of eosinophil chemokines. Altogether, our findings suggest that EVs are a common cause of respiratory tract infections in paediatric patients, where they can induce the release of chemokines by bronchial epithelial cells, which may significantly contribute to the various histologic and inflammatory features of EV-induced airway disease
