    查看更多>>摘要：Viruses are important components of the human body.Growing evidence suggests that they are engaged in the physiology and disease status of the host.Even though the vaginal microbiome is involved in human papillo-mavirus(HPV)infection and cervical cancer(CC)progression,little is known about the role of the vaginal virome.In this pilot exploratory study,using unbiased viral metagenomics,we aim to investigate the vaginal eukaryotic virome in women with different levels of cervical lesions,and examine their associations with different cervical disease status.An altered eukaryotic virome was observed in women with different levels of lesions and Lacto-bacillus profiles.Anelloviruses and papillomaviruses are the most commonly detected eukaryotic viruses of the vaginal virome.Higher abundance and richness of anelloviruses and papillomaviruses were associated with low-grade squamous intraepithelial lesion(LSIL)and CC.Besides,higher anellovirus abundance was also associated with lactobacillus-depleted microbiome profiles and bacterial community state(CST)type Ⅳ.Furthermore,increased correlations between Anelloviridae and Papillomaviridae occurred in the women with increased cervical disease severity level from LSIL to CC.These data suggest underlying interactions between different microbes as well as the host physiology.Higher abundance and diversity of both anelloviruses and papillomaviruses shared by LSIL and CC suggest that anellovirus may be used as a potential adjunct biomarker to predict the risk of HPV persistent infection and/or CC.Future studies need to focus on the clinical relevance of anellovirus abundance with cervical disease status,and the evaluation of their potential as a new adjunct biomarker for the prediction and prognoses of CC.

    198-207页
    查看更多>>摘要：Many paramyxoviruses are responsible for a variety of mild to severe human and animal diseases.Based on the novel discoveries over the past several decades,the family Paramyxoviridae infecting various hosts across the world includes 4 subfamilies,17 classified genera and 78 species now.However,no systematic surveys of bat paramyxoviruses are available from the Chinese mainland.In this study,13,064 samples from 54 bat species were collected and a comprehensive paramyxovirus survey was conducted.We obtained 94 new genome sequences distributed across paramyxoviruses from 22 bat species in seven provinces.Bayesian phylodynamic and phylo-genetic analyses showed that there were four different lineages in the Jeilongvirus genus.Based on available data,results of host and region switches showed that the bat colony was partial to interior,whereas the rodent colony was exported,and the felines and hedgehogs were most likely the intermediate hosts from Scotophilus spp.rather than rodents.Based on the evolutionary trend,genus Jeilongvirus may have originated from Mus spp.in Australia,then transmitted to bats and rodents in Africa,Asia and Europe,and finally to bats and rodents in America.

    查看更多>>摘要：Zika virus(ZIKV),a positive-sense single-stranded RNA virus,causes congenital ZIKV syndrome in children and Guillain-Barré Syndrome(GBS)in adults.ZIKV expresses nonstructural protein 5(NS5),a large protein that is essential for viral replication.ZIKV NS5 confers the ability to evade interferon(IFN)signalling;however,the exact mechanism remains unclear.In this study,we employed affinity pull-down and liquid chromatography-tandem mass spectrometry(LC-MS/MS)analyses and found that splicing factor 3b subunit 3(SF3B3)is associated with the NS5-Flag pull-down complex through interaction with NS5.Functional assays showed that SF3B3 over-expression inhibited ZIKV replication by promoting IFN-stimulated gene(ISG)expression whereas silencing of SF3B3 inhibited expression of ISGs to promote ZIKV replication.GTP cyclohydrolase Ⅰ(GCH1)is the first and rate-limiting enzyme in tetrahydrobiopterin(BH4)biosynthesis.NS5 upregulates the expression of GCH1 during ZIKV infection.And GCH1 marginally promoted ZIKV replication via the IFN pathway.Additionally,GCH1 expression is related to the regulation of SF3B3.Overexpression of the SF3B3 protein effectively reduced GCH1 protein levels,whereas SF3B3 knockdown increased its levels.These findings indicated that ZIKV NS5 binding protein SF3B3 contributed to the host immune response against ZIKV replication by modulating the expression of GCH1.

    查看更多>>摘要：Homologous booster,heterologous booster,and Omicron variants breakthrough infection(OBI)could improve the humoral immunity against Omicron variants.Questions concerning about memory B cells(MBCs)and T cells immunity against Omicron variants,features of long-term immunity,after booster and OBI,needs to be explored.Here,comparative analysis demonstrate antibody and T cell immunity against ancestral strain,Delta and Omicron variants in Omicron breakthrough infected patients(OBIPs)are comparable to that in Ad5-nCoV boosted healthy volunteers(HVs),higher than that in inactivated vaccine(InV)boosted HVs.However,memory B cells(MBCs)immunity against Omicron variants was highest in OBIPs,followed by Ad5-nCoV boosted and InV boosted HVs.OBIPs and Ad5-nCoV boosted HVs have higher classical MBCs and activated MBCs,and lower naive MBCs and atypical MBCs relative to both vaccine boosted HVs.Collectively,these data indicate Omicron breakthrough infection elicit higher MBCs and T cells against SARS-CoV-2 especially Omicron variants relative to homologous InV booster and heterologous Ad5-nCoV booster.

    查看更多>>摘要：Many studies suggest that severe acute respiratory syndrome coronavirus 2(SARS-CoV-2)can infect various animals and transmit among animals,and even to humans,posing a threat to humans and animals.There is an urgent need to develop inexpensive and efficient animal vaccines to prevent and control coronavirus disease 2019(COVID-19)in animals.Rabies virus(RABV)is another important zoonotic pathogen that infects almost all warm-blooded animals and poses a great public health threat.The present study constructed two recombinant chimeric viruses expressing the S1 and RBD proteins of the SARS-CoV-2 Wuhan01 strain based on a reverse genetic system of the RABV SRV9 strain and evaluated their immunogenicity in mice,cats and dogs.The results showed that both inactivated recombinant viruses induced durable neutralizing antibodies against SARS-CoV-2 and RABV and a strong cellular immune response in mice.Notably,inactivated SRV-nCoV-RBD induced earlier antibody pro-duction than SRV-nCoV-S1,which was maintained at high levels for longer periods.Inactivated SRV-nCoV-RBD induced neutralizing antibodies against both SARS-CoV-2 and RABV in cats and dogs,with a relatively broad-spectrum cross-neutralization capability against the SARS-CoV-2 pseudoviruses including Alpha,Beta,Gamma,Delta,and Omicron,showing potential to be used as a safe bivalent vaccine candidate against CO VID-19 and rabies in animals.

    查看更多>>摘要：Neutralizing monoclonal antibodies(mAb)are a major therapeutic strategy for the treatment of severe acute respiratory syndrome coronavirus-2(SARS-CoV-2)infection.The continuous emergence of new SARS-CoV-2 variants worldwide has increased the urgency for the development of new mAbs.In this study,we immunized mice with the receptor-binding domain(RBD)of the SARS-CoV-2 prototypic strain(WIV04)and screened 35 RBD-specific mAbs using hybridoma technology.Results of the plaque reduction neutralization test showed that 25 of the mAbs neutralized authentic WIV04 strain infection.The 25 mAbs were divided into three categories based on the competitive enzyme-linked immunosorbent assay results.A representative mAb was selected from each category(RD4,RD10,and RD 14)to determine the binding kinetics and median inhibitory concentration(IC50)of WIV04 and two variants of concern(VOC):B.1.351(Beta)and B.1.617.2(Delta).RD4 neutralized the B.1.617.2 variant with an IC50 of 2.67 ng/mL;however,it completely lost neutralizing activity against the B.1.351 variant.RD10 neutralized both variants with an IC50 exceeding 100 ng/mL;whereas RD14 neutralized two variants with a higher IC50(＞1 mg/mL).Animal experiments were performed to evaluate the protective effects of RD4 and RD10 against various VOC infections.RD4 could protect Adv-hACE2 transduced mice from B.1.617.2 infection at an antibody concentration of 25 mg/kg,while RD10 could protect mice from B.1.351 infection at an antibody concentration of 75 mg/kg.These results highlight the potential for future modifications of the mAbs for practical use.

    268-275页
    查看更多>>摘要：Hand,foot and mouth disease(HFMD)is a major public health problem among children in the Asia-Pacific region.The optimal specimen for HFMD virological diagnosis remains unclear.Enterovirus A71(EV-A71)neutralizing antibody titres detected in paired sera were considered the reference standard for calculating the sensitivity,specificity,positive and negative predictive value of throat swabs,rectal swabs,stool,blood samples and cere-brospinal fluid(CSF)by RT-PCR or ELISA assay.In this study,clinical samples from 276 HFMD patients were collected for analysing the sensitivity of different kind of specimens.Our results showed that stool had the highest sensitivity(88％,95％CI:74％-96％)and agreement with the reference standard(91％).The order of diagnostic yield for EV-A71 infection was stool sample≥rectal swab＞throat swab＞blood sample＞CSF sample,and using a combination of clinical samples improved sensitivity for enterovirus detection.The sensitivity of ELISA for IgM antibody detection in sterile-site specimens was significantly higher than that of RT-PCR(serum/plasma:62％vs.2％,CSF:47％vs.0％)(P＜0.002).In conclusion,our results suggest that stool has the highest diagnostic yield for EV-A71-infected HFMD.If stool is unavailable,rectal swabs can be collected to achieve a similar diagnostic yield.Otherwise,throat swabs may be useful in detecting positive samples.Although IgM in blood or CSF is diagnos-tically accurate,it lacks sensitivity,missing 40％-50％of cases.The higher proportion of severe cases and shorter interval between onset and sampling contributed to the increase in congruency between clinical testing and the serological reference standard.

    276-284页
    查看更多>>摘要：Enterovirus 71(EV71)poses a serious threat to human health,with scattered outbreaks worldwide.There are several vaccines against a few EV71 strains but no efficient drug for the treatment of EV71 infection.Therefore,it is urgent and of significance to develop anti-EV71 drugs.Here,we found that PLX8394,a RAF inhibitor,possesses high antiviral activity against EV71 in vitro,being superior to the traditional clinical drug ribavirin.Moreover,PLX8394 exhibits broad-spectrum antiviral activity against enteroviruses.Notably,in a suckling mouse model,PLX8394 provided a 70％protection rate for EV71-infected mice,reduced the viral load in liver and heart tissues,and relieved the inflammatory response.A mechanistic study showed that PLX8394 inhibited EV71 by sup-pressing the RAF/MEK/ERK signaling pathway.Thus,PLX8394 lays a foundation for the development of new drugs against EV71.
