Full textEnteroviruses group B (EV-B) and more specifically Coxsackievirus B are recognized as major causes of acute and chronic infectious myocarditis, which 10% may progress towards dilated cardiomyopathy (DCM). Viral molecular mechanisms involved in the progression from acute myocarditis to the clinical stage of DCM remain unknown.Deep sequencing analysis showed in 8 (33%) of 24 unexplained DCM patients the existence of major CVB3 populations with deletions of 19 to 50 nucleotides associated with a minority of complete viral forms. The proportion of deleted viral populations was negatively correlated with RNA+/RNA- ratio and the viral load levels. Immuno-histological and in situ hybridization assays of DCM cardiac tissues demonstrated that the cleavage of dystrophin was found only in cardiomyocytes infected with EV-B. To study the replication activities of persistent EV-B populations, a replicon (CVB3-emGFP) was generated from a cardiotropic strain (CV-B3/28). Transfection of synthesized complete and truncated (d50) viral RNAs in primary human cardiomyocytes cultures revealed mechanisms of recombination and / or trans-complementation between these two viral forms inducing low replication activities.In conclusions, our original results demonstrated the existence of new molecular mechanisms of cooperation between EV-B deleted and complete viral populations that could explain the development of a viral persistence mechanism observed during the clinical phase of DCM. These findings may contribute to the development of new therapeutic strategies to prevent and treat persistent heart EV-B infections

Full textThe present study aims at investigating the potential of bifidobacteria in protecting cells from Coxsackievirus B4 (CV-B4) infection. The bifidobacterial screening identified two out of five strains that protected HEp-2 cell viability when bifidobacteria were incubated with the viral particles prior inoculation. In contrast, no effect was shown by incubating HEp-2 cells with bifidobacteria prior CV-B4 inoculation. Cell-wall lipoproteins secreted by the selected strains (LpAs) were assayed for their anti-viral activity. The two LpAs exhibited anti-viral activity when they were incubated with the viral particles prior inoculation to HEp-2 cells. No effect was induced by incubating LpAs with HEp-2 cells prior CV-B4 inoculation. The recombinant LpAs derived-protein exhibited identical anti-viral activity. To identify the peptide sequences interacting with the virus particles, LpAs proteins were aligned with the peptide sequences of north canyon rim and puff footprint onto coxsackievirus and adenovirus receptor (CAR). The in silico molecular docking study using CV-B3 as template showed a low energy binding indicating a stable system for the selected peptides and consequently a likely binding interaction with CV-B. B.longum and B.breve peptides homologous to the viral north rim footprint onto CAR sequence formed hydrogen bonds with several viral residues in the north rim of the canyon, which were already predicted as interacting with CAR. In conclusion, proteins from bifidobacterial LpAs can inhibit the infection with CV-B4 likely through binding to the capsid aminoacids that interact with CAR

Full textMajor enterovirus (EV) populations characterized by 5’ terminal genomic RNA deletions (TD) ranging up to 50 nucleotides were previously identified in cardiac tissues from acute myocarditis and chronic dilated cardiomyopathy (DCM) patients. Dynamics of emergence and impact of various EV-TD populations onto the inflammatory response remains unknown. Using a PCR-MS approach EV-RNAs were detected alone (32%) or with PVB19 genomes in 48 % of patients with an idiopathic DCM. Among these patients, EV- RNA was associated with a positive endomyocardial CD3, CD68 ou HLA-DR immunostaining. In these EV-DCM cases, a quantitative "RACE-PCR" system showed that 37 to 50 nt EV-TD forms were the major persistant viral populations (80%) in association with 15 to 36 nt EV-TD (19%) and full-length (FL) (1%) forms. In samples from myocarditis cases, levels of 37 to 50 nt EVB-TD forms (84%) appeared to be statistically higher than other EV-TD (8%) and FL forms (8%) (P<10-3). Among severe myocarditis cases subgroup, levels of 15 to 36 nt EV-TD forms were significantly higher (P=0.02)) and associated with higher IFN-β mRNA levels (P=0.02)) than in non-severe myocarditis patients. HCM transfection of synthetic 8 to 36 nt EV-TD forms induced higher IFN-β mRNA (P<10-3) and cytokine levels (P=0.02) comparatively to those obtained after transfection by others deleted EV RNA forms. EV-RNA TD populations appeared to be major in acute myocarditis and DCM cases. Moreover, the proportions of minor 15 to 36nt EV-TD forms could modulate the innate immune sensing mechanisms in cardiomyocytes and therefore the clinical severity of cardiac infection

Full textThe resistance of viruses to drying relies on several factors : the type of surface, temperature, humidity and the compositon of the viral envelope or capsid. A virus adsorbed on a surface can remain infectious for several days or months if the conditions are met. [...] In this thesis, methods were developed to compare the virucidal activity of disinfectants towards viruses in suspension and on surfaces (stainless steel or non-woven fuctionalized textiles). Two approaches were implemented : the first to test the virudical activity of functionalized surfaces

Kalanchoe gracilis (Crassulaceae) is a traditional Chinese medicinal, a.k.a. Da-Huan-Hun, and usually used in injuries, pain, fever and inflammation in Taiwan. In 1998, enterovirus 71 (EV71) and coxsackie A16 (CVA16) outbroke with severe or even fatal cases occurred in Taiwan, causing public health concern. EV71 and CVA16 become two major endemic agents of HFMD in children in Taiwan. There are not yet specific vaccines or antiviral drugs for treating enterovirus infection in clinic. In this study, extracts and compounds of K. gracilis leaf and stem were divided into two groups for investigating the antiviral activities against EVs. HPLC analysis indicated leaf and stem extracts exhibiting different ingredients, such as ferulic acid, quercetin and kaempferol in the leaf extract, as well as caffeic acid and eupafol in stem extracts. Plaque reduction assay indicated IC50 values of K. gracilis leaf extract were 35.88 μg/ml for EV71, and 42.91 μg/ml for CVA16, repectively. Leaf extract showed potent activity in the procedures of pre- and post-treatment for virus. Leaf extract inhibit the virus yield production to 90%. IC50 values of K. gracilis leaf extract in cell-based FRET assay were 40.82 μg/ml for EV71 and 47.84 μg/ml for CVA16. IC50 value of K. gracilis leaf extract in 2A protease assay was 32.46 μg/ml for EV71. The result implied K. gracilis leaf extract inhibited the proteolytic activity of EV71 and CVA16 2A proteases. K. gracilis leaf extract also revises the NF-κB-mediated signaling that induced by the virus infected. K. gracilis leaf extract effective against enterovirus is via inhibited viral replication and viral 2A protease activity. In the other hand, K. gracilis stem extract, EA fraction, BuOH fraction and relative compounds processed low cyotoxicity. IC50 values of K. gracilis stem extract were 75.18 μg/mL for EV71, and 81.41 μg/mL for CVA16, respectively. Anti-EV activity of stem extract was weaker than leaf extract, but stem extract potently inhibited EVs replication. EA and BuOH fractions of stem extract also showed the competence on inhibiting viral 2A protease enzymatic activity. Among the ingredients, eupafolin reduced virus-induced expression of IL-6 and RANTES. In vivo experiments proved leaf and stem extract potently inhibiting viral titers in intestines of infected mice. Together with data of two parts showed K. gracilis extracts as potent therapeutics against EV71 and CVA16. K. gracilis, an indigenous herbal plant in Taiwan, could easily cultivate and develop antiviral drugs for treatment and prevention against EV71 and CVA16 infections.

Human enteroviruses (HEVs) belong to the picornavirus family, and are associated with diverse clinical syndromes ranging from minor febrile illness to severe, potentially fatal conditions. A number of anti-HEV compounds have been developed, mainly targeting HEV capsid and 3C protease. Despite the sustained effort, treatment of HEV infection remains a significant unmet medical need, partly due to the development of drug resistance. In this study, we focused on the inhibition of HEV 2A protease (2Apro), an enzyme pivotal in HEV multiplication and pathogenesis. We utilized MPCMK, an irreversible inhibitor demonstrated to target some HEV serotypes in cell culture. The potential for resistance was studied following in vitro serial passage of two representative HEV strains, enterovirus 71 (EV 71) and coxsackievirus B3 (CB3), in the presence of increasing MPCMK concentrations. No significant increase in the 50% effective concentration (EC50) of EV 71 was measured following up to five passages exposed to MPCMK ranging from 0.025-0.4 mM at two-fold increases. Genotypic analyses of the EV 71 2Apro revealed only a nucleotide mutation that leads to alteration of amino acid sequences at the fifth passage. Phenotypic analyses of CB3 indicated slight yet statistically significant increases in EC50s, and the results obtained by the novel FRET-based assay and the conventional dye reduction assay were highly correlated. In summary, no significant reductions in susceptibility to the 2Apro inhibitor highlight the advantages of 2Apro as an antiviral target.
