Fig; IRAV; MOV10; RNA summary = title: IRAV (FLJ11286), an Interferon-Stimulated Gene with Antiviral Activity against Dengue Virus, Interacts with MOV10 IRAV is an RNA binding protein and localizes to cytoplasmic processing bodies (P bodies) in uninfected cells, where it interacts with the MOV10 RISC complex RNA helicase, suggesting a role for IRAV in the processing of viral RNA. FLJ11286, which we refer to here as IRAV (interferon-regulated antiviral gene) (also annotated as C19orf66, UPF0515, or RyDEN), encodes a protein 291 amino acids (aa) in length with a calculated molecular mass of 33.1 kDa. Analysis of published microarray data suggests that IRAV (FLJ11286) is upregulated in response to type I and type II IFNs (6, 20, (24) (25) (26) . IRAV also associates with the host RNA binding proteins UPF1 and HuR (ELAV1) and interacts with MOV10 (a RISC complex RNA helicase), suggesting a role for IRAV in processing or stability of RNA. doi = 10.1128/jvi.01606-16 id = cord-290385-0smnl70i author = Chan, Jasper F.W. title = Zika fever and congenital Zika syndrome: An unexpected emerging arboviral disease date = 2016-03-03 keywords = Aedes; Brazil; DENV; ZIKV; Zika; infection; virus summary = doi = 10.1016/j.jinf.2016.02.011 id = cord-303818-z3js3mr4 author = Chen, Huixin title = Development and Evaluation of a SYBR Green–Based Real-Time Multiplex RT-PCR Assay for Simultaneous Detection and Serotyping of Dengue and Chikungunya Viruses date = 2015-10-11 keywords = CHIKV; DENV; PCR summary = doi = 10.1016/j.jmoldx.2015.06.008 id = cord-274129-vaygaqe5 author = Cheng, Ming Soon title = Impedimetric cell-based biosensor for real-time monitoring of cytopathic effects induced by dengue viruses date = 2015-08-15 keywords = CPE; DENV; MOI; PLL summary = doi = 10.1016/j.bios.2015.03.018 id = cord-317169-qlqavi4t author = Chiow, K.H. title = Evaluation of antiviral activities of Houttuynia cordata Thunb. extract, quercetin, quercetrin and cinanserin on murine coronavirus and dengue virus infection date = 2015-12-19 keywords = DENV-2; MHV summary = (Saururaceae) and three of its constituent flavonoids (quercetin, quercitrin and rutin) against murine coronavirus and dengue virus (DENV). cordata and flavonoids were assessed using virus neutralization tests against mouse hepatitis virus (MHV) and DENV type 2 (DENV-2). Certain flavonoids exhibited comparatively weaker antiviral activity, notably quercetin which could inhibit both MHV and DENV-2. This was followed by quercitrin which could inhibit DENV-2 but not MHV, whereas rutin did not exert any inhibitory effect on either virus. cordata contribute to the superior antiviral efficacy of the EA fraction which lacked cytotoxicity in vitro and acute toxicity in vivo. cordata exhibited anti-MHV activity at a MIC of 0.98 mg/mL without any apparent cytotoxic effects on CCL9.1 cells. cordata and its flavonoid component, quercetin, could inhibit both MHV and DENV-2 in vitro.

The study objectives were to estimate the seroprevalence of arboviruses in the urban population of Solomon Islands while using qPCR to determine the circulating viruses from the clinical samples; furthermore, to characterize and compare the dengue virus isolated from our study to previous published isolates from the region using the phylogenetic tree analysis. The high positivity rate for anti-DENV IgG antibodies (77.9%) and the high DENV positivity rate detected in the qPCR analysis of the clinical samples (76.3%) were indicative of a high number of secondary infections in the 2016 outbreak. The phylogenetic tree analysis and the serotypespecific qPCR results indicated that there was a single DENV-3 serotype in circulation from 2012 to 2016 in Solomon Islands. doi = 10.1186/s41182-020-00217-8 id = cord-318120-vfznyyz6 author = Dauner, Allison L. title = Development of a pan-serotype reverse transcription loop-mediated isothermal amplification assay for the detection of dengue virus date = 2015-05-15 keywords = DENV; LAMP; PCR summary = title: Development of a pan-serotype reverse transcription loop-mediated isothermal amplification assay for the detection of dengue virus To facilitate needed diagnosis, we developed and optimized a reverse transcription loop-mediated isothermal amplification (RT-LAMP) assay that detects all 4 serotypes of dengue virus (DENV).

In addition, no significant reduction in viral protein or RNA levels was seen in WNV replicon-expressing cells transfected with siRNAs targeting the NS3 gene using lipid-based reagents. Also, a recent report showed that siRNA toward the TNF-a gene reduced cytokine response in DENV-infected DCs, highlighting the potential of targeted RNAi-based approaches to simultaneously decrease viral replication and the detrimental host immune response (Subramanya et al., 2010) . In addition, it has been shown that WNV (Chotkowski et al., 2008) and DENV (Mukherjee & Hanley, 2010) infection (Mukherjee & Hanley, 2010) of Drosophila cell lines induce functional virus-specific siRNAs that promote a protective RNAi response. So far we have described the antiviral effect of the RNAi mechanism induced by exogenous delivery of siRNA or precursors, and how cellular miRNA can target sequences artificially introduced within the genome of flaviviruses. doi = 10.1016/b978-0-12-408116-1.00004-5 id = cord-011026-iapgkz0p author = El-Bitar, Alaa M.

For dengue virus infectivity, serially diluted venom fractions and Smp76 were mixed with fixed amount of DENV and incubated for 2 h at 37 °C. The above results suggest that the Smp76 directly affects HCV particles and/or host cells in the culture medium to inhibit the viral infection and does not have an antiviral effect in the cells. To determine whether the antiviral activity of Smp76 peptide (previously described) was specific to HCV and DENV, a Schematic of infection assay. The exact mechanism by which Smp76 exerts its antiviral activity against HCV and DENV to inhibit infecting their target cells need further studies. doi = 10.1007/s10989-019-09888-2 id = cord-002426-5e1xn7kj author = Falcón-Lezama, Jorge Abelardo title = Analysis of spatial mobility in subjects from a Dengue endemic urban locality in Morelos State, Mexico date = 2017-02-22 keywords = DENV; case; control summary = MATERIALS AND METHODS: We carried out a cohort-nested, case-control study with 126 individuals (42 cases, 42 intradomestic controls and 42 population controls) with the goal of describing human mobility patterns of recently Dengue virus-infected subjects, and comparing them with those of non-infected subjects living in an urban endemic locality. CONCLUSIONS: Results of this study show that human mobility in a small urban setting exceeded that considered by local health authority''s administrative limits, and was different between recently infected and non-infected subjects living in the same household. These observations provide important insights about the role that human mobility may have in Dengue virus transmission and persistence across endemic geographic areas that need to be taken into account when planning preventive and control measures. Sample: 126 individuals (42 cases, 42 intradomestic controls and 42 population controls) with age older than 12, and residents in Axochiapan, Morelos State, México, were selected from the cohort "Peridomestic infection as determinant for Dengue virus transmission" [13] . doi = 10.1371/journal.pone.0172313 id = cord-273065-peqz7okh author = Girard, Marc title = Arboviruses: A global public health threat date = 2020-04-24 keywords = Aedes; Brazil; DENV; ZIKV; dengue summary = doi = 10.1016/j.vaccine.2020.04.011 id = cord-278260-3o91v72a author = Halstead, Scott B title = COVID 19 Vaccines: Should we fear ADE? date = 2020-08-12 keywords = ADE; DENV; SARS summary = Within months large numbers of vaccinated children developed a severe breakthrough disease, called "atypical measles." [6] A similar outcome, "vaccine associated enhanced respiratory disease (VAERD)," was observed in infants, 4 -12 months of age, who were given formalininactivated respiratory syncytial virus (RSV) and a few months later infected by RSV. The biological behavior of some coronaviruses in non-human species together with evidence that human coronavirus antibodies enhanced infection of SARS or MERS CoVs in Fc receptor-bearing cells, in vitro, have led to speculations that ADE contributes to disease severity in humans. [11] It has been reported that high levels of SARS CoV-1 IgG antibodies circulated in severe SARS cases and that anti-S IgG neutralizing antibody (NAb) responses developed significantly faster after the onset of clinical symptoms in fatal compared with recovered cases leading some to attribute enhanced tissue damage to ADE. With others, we conclude that the differences in clinical, epidemiological and pathological features of SARS and DENV diseases suggest that iADE does not contribute to the severity of natural human coronavirus infections. doi = 10.1093/infdis/jiaa518 id = cord-285538-3ah05ijf author = Halstead, Scott B. title = Chapter 19 Pathogenic Exploitation of Fc Activity date = 2014-12-31 keywords = ADE; DENV; IL-10; Leishmania; dengue summary = 3, 4 While follow-up research in the 1960s suggested that this phenomenon resulted from the stabilization of MVEV by antibodies, 5 a different explanation emerged when sequential infections in humans with dengue viruses (DENVs) were shown to produce severe disease (dengue hemorrhagic fever, DHF). Unexpectedly, the incubation of Ross River virus (RRV) with diluted RRV antiserum resulted in enhanced infection in mouse macrophage cell lines and in primary human monocytes/macrophages via innate immune suppression involving reduced production of reactive nitrogen radicals via NOS2 and a downregulation of TNF-α and IFN-β production through abolished interferon regulatory factor 1 (IRF-1) and nuclear factor-κB gene expression. 43 Note has been made above of the possible role of different Fcγ receptors in mediating ADE in macrophages in leishmania mouse models and the interesting observation suggesting that ligation of FcγRIIB may affect the fate of large immune complexes during the immune clearance phase of dengue infections. doi = 10.1016/b978-0-12-394802-1.00019-4 id = cord-273388-615acz0l author = He, Miao title = The Impact of Emerging Infectious Diseases on Chinese Blood Safety() date = 2016-11-04 keywords = China; DENV; EID; blood; chinese summary = doi = 10.1016/j.tmrv.2016.10.002 id = cord-272459-w14finxf author = Heaton, Nicholas S. title = Dengue Virus and Autophagy date = 2011-08-04 keywords = DENV; autophagy; replication summary = Recently, it was reported that autophagy plays an indirect role in DENV replication by modulating cellular lipid metabolism. Relevant to DENV infection, a type of selective autophagy termed lipophagy was described, wherein autophagosomes can target cellular stores of lipids known as lipid droplets (LDs) to generate energy for the cell [38] . In subsequent work, the authors reproduced the published results that DENV induces and requires autophagy for robust viral replication [39] . These autophagosomes did not co-localize with markers of the viral replication complex, suggesting that they may play an indirect, non-structural role in DENV replication. Alternatively, DENV infection induces a selective autophagy that is preferentially targeted to lipid droplets, which leads to changes in cellular metabolism. More work, however, is required to show whether the proposed viral triggers of autophagy reproduce all cellular signals and phenotypes that accompany autophagy induction in DENV-infected cells. doi = 10.3390/v3081332 id = cord-355610-7xy4s483 author = Hu, Dan title = A broadly neutralizing germline-like human monoclonal antibody against dengue virus envelope domain III date = 2019-06-26 keywords = DENV; DIII; Fig; antibody; m366.6 summary = doi = 10.1371/journal.ppat.1007836 id = cord-355179-wmfwl2bh author = Jung, Eunhye title = Neutralization of Acidic Intracellular Vesicles by Niclosamide Inhibits Multiple Steps of the Dengue Virus Life Cycle In Vitro date = 2019-06-18 keywords = DENV; Fig; RNA; niclosamide summary = Overall, the data indicate that the antiviral activity of niclosamide during the early stage of the DENV life cycle correlates with the neutralization profile of the low-pH compartments, suggesting that blocking endosomal acidification results in the inhibition of viral genome replication and polyprotein processing, which further impedes viral protein expression and virus production. In this study, we found that neutralization of low-pH intracellular compartments by niclosamide not only inhibited the early stage of the DENV viral life cycle, such as viral RNA replication, independent of the entry step but also the late stage, specifically, the maturation of virus particles into infectious virions. Indeed, niclosamide treatment www.nature.com/scientificreports www.nature.com/scientificreports/ during the first 6 h of infection reduced DENV replication in BHK-21 cells harbouring dengue replicons to a level comparable to that of ribavirin, suggesting that the drug affects viral RNA replication and/or translation independent of its effect on entry, membrane fusion and genome release. doi = 10.1038/s41598-019-45095-1 id = cord-342157-qjyooq68 author = King, Chwan-Chuen title = Comparative analysis of full genomic sequences among different genotypes of dengue virus type 3 date = 2008-05-21 keywords = DHF; Taiwan; dengue; denv-3 summary = In our study, complete genomic sequencing of DENV-3 strains collected from different geographical locations and isolation years were determined and the sequence diversity as well as selection pressure sites in the DENV genome other than within the E gene were also analyzed. RESULTS: Using maximum likelihood and Bayesian approaches, our phylogenetic analysis revealed that the Taiwan''s indigenous DENV-3 isolated from 1994 and 1998 dengue/DHF epidemics and one 1999 sporadic case were of the three different genotypes – I, II, and III, each associated with DENV-3 circulating in Indonesia, Thailand and Sri Lanka, respectively. Compared to the prototype strain H87, several unique amino acid substitutions that serve as unique signature sites for each genotype were found within the full genomic sequences of the selected DENV-3 isolates from Taiwan or other countries and are listed by the order of the gene in Table 3 . doi = 10.1186/1743-422x-5-63 id = cord-011968-abd891ej author = Lai, Yen-Chung title = Roles of Macrophage Migration Inhibitory Factor in Dengue Pathogenesis: From Pathogenic Factor to Therapeutic Target date = 2020-06-12 keywords = DENV; MIF; dengue; infection summary = Macrophage migration inhibitory factor (MIF) is a pleiotropic proinflammatory cytokine that mediates diverse immune responses, and the serum level of MIF positively correlates with disease severity in patients with dengue. In another study, it was demonstrated that live DENV2-induced endoplasmic reticulum (ER) stress is required for autophagy activation, viral replication and pathogenesis in HuH-7 and A549 cells [57] . In our study, since UV-inactivated viral particles could not induce MIF secretion or expression, it is possible that DENV infection triggered RNA sensing or pattern recognition receptor (PRR) activation, which was followed by the release of preformed MIF from the cytosol through the vesicle trafficking secretory pathway.

Clinicians from Singapore reported two COVID-19 cases that were misdiagnosed as dengue among patients who presented with clinical manifestations and hematology profiles, suggesting dengue infection and false-positive DENV IgM antibody using a rapid diagnostic test (RDT). COVID-19 cases were defined as inpatients who met the COVID-19 criteria based on a predetermined combination of symptoms, laboratory testing, imaging, and risk exposure at Tangerang District Hospital, Indonesia (see Supplemental Table 1 ), and had a positive nasopharyngeal or oropharyngeal real-time RT-PCR for SARS-CoV-2. None of the 42 subjects was positive for dengue NS1 or showed seroconversion or increasing DENV IgM and IgG index values, suggesting no acute DENV infection among these COVID-19 cases. The third patient did not recall having a fever before acute COVID-19 illness, suggesting asymptomatic or mild dengue, the most common presentation of DENV infection. doi = 10.4269/ajtmh.20-0676 id = cord-002581-r7mskri0 author = Magnani, Diogo M. title = A human inferred germline antibody binds to an immunodominant epitope and neutralizes Zika virus date = 2017-06-12 keywords = DENV; P1F12; ZIKV; Zika; virus summary = doi = 10.1371/journal.pntd.0005655 id = cord-033331-giku34r9 author = Manrique-Saide, Pablo title = The TIRS trial: protocol for a cluster randomized controlled trial assessing the efficacy of preventive targeted indoor residual spraying to reduce Aedes-borne viral illnesses in Merida, Mexico date = 2020-10-08 keywords = Aedes; DENV; Health; TIRS; Yucatan; abv summary = doi = 10.1186/s13063-020-04780-7 id = cord-355489-tkvfneje author = Mendez, Jairo A title = Phylogenetic history demonstrates two different lineages of dengue type 1 virus in Colombia date = 2010-09-14 keywords = Colombia; DENV-1; PCR; dengue; virus summary = Yet, the phylogenetic relationships between strains isolated along the covered period of time suggests that viral strains detected in some years, although belonging to the same genotype V, have different recent origins corresponding to multiple re-introduction events of viral strains that were circulating in neighbor countries.

Previously reported genotypes were represented in the tree and placed most of the Colombian isolates nesting in the genotype V clade (America, Africa) and were closely related to Argentina, Brazil and Paraguay virus strains. doi = 10.1186/1743-422x-7-226 id = cord-355906-yeaw9nr8 author = Nedjadi, Taoufik title = Tackling dengue fever: Current status and challenges date = 2015-12-09 keywords = Aedes; DENV; dengue; infection; vaccine; virus summary = doi = 10.1186/s12985-015-0444-8 id = cord-276718-3lujp0oy author = Neeraja, M. title = Rapid detection and differentiation of dengue virus serotypes by NS1 specific reverse transcription loop-mediated isothermal amplification (RT-LAMP) assay in patients presenting to a tertiary care hospital in Hyderabad, India date = 2014-10-24 keywords = DENV; LAMP; PCR summary = title: Rapid detection and differentiation of dengue virus serotypes by NS1 specific reverse transcription loop-mediated isothermal amplification (RT-LAMP) assay in patients presenting to a tertiary care hospital in Hyderabad, India In the present study, the standardization and validation of a one step, four tube reverse transcription loop-mediated isothermal amplification assay (RT-LAMP) for rapid detection and serotyping of the DENV targeting NS1 gene using the Genie® II flourometer was carried out.

Moreover, results from time-of-addition study showed that the inhibitory effect of CBX on DENV was exhibited by targeting the virus itself, not the host cells. In this study, we investigated whether CBX treatment inhibits dengue infection by measuring the production of progeny virions and viral RNA as well as viral protein expression. To determine whether CBX inhibits the production of infectious progeny DENV in other dengue-permissive cells, TCID 50 assay was performed to measure the virus titer in CBX-treated THP-1 and HUVEC cells, both of which are widely used in DENV studies [Halstead, 1988; Wu et al., 2000] .

IL-1β secretion further enhances the production and release of IL-23 and IL-6 and the association of IL-18, IL-1β, and IL-23 stimulate Th17/γδ T cells to generate pro-inflammatory cytokines (GM-CSF, IL-17A, IL-17F, IL-22,) that create the stage for host adaptive immune responses during DENV infection (Wu et al., 2013a) . Another study demonstrated that DENV infects DC and induces NLRP3 inflammasome activation, triggering ROS production in mitochondria that leads to the discharge of mitochondrial DNA (mtDNA) into the cytosol.

Clinical predictors of laboratory-positive dengue compared to all other AFI etiologies were determined by age and day post-illness onset (DPO) at presentation. By enrolling febrile patients at clinical presentation, we identified unbiased predictors of laboratory-positive dengue as compared to other common causes of AFI. Among 6,349 participants who presented early (<3 DPO) in the clinical course, leukopenia, thrombocytopenia, headache, eye pain, nausea, and dizziness were significant positive predictors of laboratory-positive dengue as compared to all other AFI cases across all age groups ( Table 5 ).

Development of a quantitative thiouridine cross-linking mass spectrometry (qTUX-MS) method for identification of proteins associated with the DENV RNA TUX-MS can be used to identify host factors by incorporating 4-thiouridine (4sU), a zero-distance cross-linker, into the viral RNA (vRNA) to enable cross-linking of proteins bound to vRNA during a live infection in cell culture [15] . Since some of hnRNPs are known to modulate cellular gene expression in response to dengue infection [60, 61] , we can not rule out that some of the observed effects on virus titers derive from their roles in regulating host mRNAs. Among the numerous qTUX-MS identified factors of interest, our study is the first to demonstrate the involvement of HMCES (or C3orf37) in viral infection. doi = 10.1371/journal.pntd.0004921 id = cord-276364-zyw5aukk author = Wong, Ho Him title = Manipulation of autophagy by (+) RNA viruses date = 2019-08-08 keywords = DENV; HCV; RNA; autophagy; virus summary = Over the past few decades, a growing body of research has defined the critical role of this pathway in facilitating infection by numerous +RNA RNA viruses, including poliovirus (PV) [7, 8] , Coxsackievirus B3 (CVB3) [9, 10] , CVB4 [11] , Enterovirus 71 (EV71) [12] , Human rhinovirus (HRV) [13] , Foot-and-mouth disease virus (FMDV) [14] , encephalomyocarditis virus (EMCV) [15] , Dengue virus (DENV) [16, 17] , Zika virus (ZIKV) [18, 19] , Hepatitis C virus (HCV) [20] , Mouse hepatitic virus (MHV), Newcastle disease virus (NDV) [21] , Severe and acute respiratory syndrome coronavirus (SARS-CoV) [22] , Chikungunya virus (ChikV) [23] , and Japanese encephalitis virus (JEV) [24] .

Since high mannose binding DC-SIGN interacts only with N67 glycans on the viral surface (Pokidysheva et al., 2006) and N153-glycan is dispensable for virus production in mosquito and mammalian cells (Bryant et al., 2007) , this suggests that N153 glycans may serve a distinct function from N67 glycans in DEN pathogenesis possibly via interaction with an unknown fucose binder or act as a viral glycan shield. Finally, N153 deglycosylated (N153 − ) DENV mutant displayed reduced infectivity (10-fold lower) in both mammalian and mosquito cells compared to WT, possibly due to impaired virus entry process (Lee et al., 1997; Hacker et al., 2009) , whereby loss of the N153-glycan affected the conformational stability of E proteins and led to premature exposure of the fusion peptide (Yoshii et al., 2013) .

Since 1990, however, DENV1 has been mainly isolated from the infected cases, and its continued existence in Guangdong Province indicated that endemic infectious agents of dengue may be circulating locally. With the epidemiological data since 2005 supplied by the Guangdong Provincial CDC, we studied phylogenetics, molecular characteristics, and epidemiology to strengthen the foundational research of DENV1 for the prevention of large-scale dengue epidemics, providing preventive and control measures of DF with important evidence. Based on representative strains of the E gene in lineages of the 2014 outbreak, as well as the molecular evolution database, we analyzed molecular characterization and possibility of local circulation for DENV1 since 2005 in Guangdong. doi = 10.4269/ajtmh.18-0951 id = cord-330743-o11d0aa1 author = Yu, Xi title = Broad-spectrum virucidal activity of bacterial secreted lipases against flaviviruses, SARS-CoV-2 and other enveloped viruses date = 2020-05-25 keywords = DENV; SARS; ZIKV summary = Herein, we identified 2 secreted bacterial lipases from a Chromobacterium bacterium, named Chromobacterium antiviral effector-1 (CbAE-1) and CbAE-2, with a broad-spectrum virucidal activity against dengue virus (DENV), Zika virus (ZIKV), severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), human immunodeficiency virus (HIV) and herpes simplex virus (HSV).

Although there was no significant direct virucidal activity against DENV-2 by quercetin, continuous treatment of cells from 5 h before virus infection up to 4 days post-infection exhibited anti-dengue activity with IC 50 = 28.9 μg mL -1 (Figure 3a) . There was no significant change in the antiviral activity of daidzein when cells were treated continuously from 5 h before virus infection up to 4 days post infection comparing to its anti-dengue activity for postadsorption treatment (Figure 1 ).
