The KM cells were subcultured for more than 70 passages and showed high viability after long-term cryopreservation. The KM cell line was optimally cultured in medium 199 containing 10% foetal bovine serum at 25°C. A chromosome analysis indicated that the cell line remained diploid, with a mean chromosome count of 100. DNA sequencing and comparative analysis of the 16S rRNA and cytochrome oxidase I gene sequences showed that the KM cell line originated from koi. In transfection experiments using the plasmid pEGFP, KM cells demonstrated a high level of transfection efficiency, suggesting their potential for use in foreign gene expression studies. Inoculation with spring viraemia of carp virus (SVCV) resulted in a substantial cytopathic effect, and the level of production of SVCV in KM cells was higher than that in the epithelioma papulosum cyprinid (EPC) cell line that is normally used to produce the virus. However, no cytopathic effect was observed when these cells were inoculated with koi herpesvirus, carp oedema virus, or grass carp reovirus. These observations suggest that the newly established KM cell line will be a valuable tool for investigating the pathogenesis of infection with spring viraemia of carp virus.</p></div>","PeriodicalId":8359,"journal":{"name":"Archives of Virology","volume":"169 12","pages":""},"PeriodicalIF":2.5,"publicationDate":"2024-11-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142613722","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}

Four pairs of compatible primers, one specific for each virus, were designed based on conserved sequences. After optimization of parameters such as primer concentration and annealing temperature in single and multiple amplifications, four specific fragments were amplified simultaneously with high sensitivity and specificity in one PCR reaction. The fragments amplified were 165 bp (CBoV), 345 bp (CCV), 506 bp (TTCV), and 666 bp (CKV) in length. The sensitivity of this one-step multiplex PCR is about 10 times lower than that of regular singleplex PCR. There was no cross-reaction with the canine pathogens canine parvovirus (CPV), canine distemper virus (CDV), or canine coronavirus (CCoV). Testing of canine fecal samples from China using the multiplex PCR assay revealed the presence of CBoV, CCV, TTCV, and CKV in 10.1%, 6.2%, 2.8%, and 1.7% of the samples, respectively. The results of multiplex PCR agreed with the singleplex PCR results with a coincidence rate of 100%.

Patients with hepatitis B virus (HBV) infection are more likely to have the NLRX1 mutation <i>p.Arg707Cys</i> than healthy individuals. It has been reported that NLRX1 increases the infection rate of HBV in HepG2 cells expressing sodium taurocholate cotransporting polypeptide (NTCP). However, the role of NLRX1 mutation (<i>p.Arg707Cys</i>) in hepatitis remains unclear. We constructed Huh7 cells that stably overexpressed NTCP, using LV003 lentivirus. First, wild-type (WT) and mutant (MT) NLRX1 overexpression plasmids were constructed. The MT plasmid contained a point mutation at position 707 of the WT overexpression plasmid. Then, Huh7-NTCP cells were transfected with the WT or MT NLRX1 overexpression plasmid, and subsequent NLRX1 expression was analyzed using real-time quantitative polymerase chain reaction (RT-qPCR) and western blot. HBV RNA levels were determined using RT-qPCR. HBsAg and HBcAg levels were confirmed immunohistochemically. Interferon alpha (IFN-α), interleukin 6 (IL-6), and type I interferon beta (IFN-β) levels were determined using enzyme-linked immunosorbent assay kits. p-p65, p-interferon regulatory factor (IRF) 3, and p-IRF7 expression levels were examined using western blot. The interaction of NLRX1 and retinoic acid-inducible gene (RIG)-1/mitochondrial antiviral signaling (MAVS) protein was confirmed by coimmunoprecipitation. The interaction of NLRX1 with IFN-α, IL-6, or IFN-β was analyzed by dual luciferase reporter gene assay. The levels of HBV RNA, HBsAg, and HBcAg in infected cells transfected with the WT NLRX1 or MT NLRX1 expression plasmid were higher than those in the untransfected control group; and these levels were lower in the cells transfected with MT NLRX1 than in those transfected with WT NLRX1. The levels of IFN-α, IFN-β, IL-6, p-p65, p-IRF3, and p-IRF7 were lower in cells transfected with WT NLRX1 or MT NLRX1 than in control cells. The levels of IFN-β, p-p65, p-IRF3, and p-IRF7 were higher in cells transfected with MT NLRX1 than in those transfected with WT NLRX1. Moreover, NLRX1 competitively inhibited RIG1 binding to MAVS, but the mutation in MT NLRX1 reduced this inhibitory effect. In addition, NLRX1 decreased the promoter activity of IFN-α, IFN-β, and IL-6. Our findings revealed that NLRX1 is a regulatory factor that inhibits the anti-HBV ability of hepatocytes and that the mutation <i>p.Arg707Cys</i> in NLRX1 suppresses HBV infection and activates the IFN/nuclear factor κB pathway.</p></div>","PeriodicalId":8359,"journal":{"name":"Archives of Virology","volume":"169 11","pages":""},"PeriodicalIF":2.5,"publicationDate":"2024-11-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://link.springer.com/content/pdf/10.1007/s00705-024-06133-0.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142579397","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The lack of a reliable cell culture system and a small-animal model has hampered our understanding of the molecular mechanism of replication of hepatitis E virus (HEV) genotype 1. Our recent identification of a replicative ensemble of mutant HEV RNA libraries has allowed us to study the metabolic prerequisites for HEV replication. Initial assessments revealed increased glucose and glutamine utilization during HEV replication. Inhibition of glycolysis and glycolysis + glutaminolysis reduced the levels of HEV replication to similar levels. An integrated analysis of protein-metabolite pathways suggests that HEV replication markedly alters glycolysis, the TCA cycle, and glutamine-associated metabolic pathways. Cells supporting HEV replication showed a requirement for fructose-6-phosphate and glutamine utilization through the hexosamine biosynthetic pathway (HBP), stimulating HSP70 expression to facilitate virus replication. Observations of mannose utilization and glutamine dependence suggest a crucial role of the HBP in supporting HEV replication. Inhibition of glycolysis and HSP70 activity or knockdown of glutamine fructose-6-phosphate amidotransferase expression led to a substantial reduction in HEV RNA and ORF2 expression accompanied by a significant decrease in HSP70 levels. This study demonstrates that glucose and glutamine play critical roles in facilitating HEV replication.</p></div>","PeriodicalId":8359,"journal":{"name":"Archives of Virology","volume":"169 11","pages":""},"PeriodicalIF":2.5,"publicationDate":"2024-10-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142540511","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}
