Abstract
Rhinovirus (RV) is the most common respiratory virus affecting humans. The majority of asthma deteriorations are triggered by RV infections. However, whether the effects of RV single- and double-stranded RNA on asthma deterioration have common target genes needs to be further studied. In the present study, two datasets (GSE51392 and GSE30326) were used to screen for common differentially expressed genes (cDEGs). The molecular function, signaling pathways, interaction networks, hub genes, key modules and regulatory molecules of cDEGs were systematically analyzed using online tools such as Gene Ontology, Kyoto Encyclopedia of Genes and Genomes, STRING and NetworkAnalyst. Finally, the hub genes STAT1 and IFIH1 were verified in clinical samples using reverse transcription-quantitative PCR (RT-qPCR). A total of 85 cDEGs were identified. Function analysis revealed that cDEGs served an important role in the innate immune response to viruses and its regulation. Signal transducer and activator of transcription 1 (STAT1), interferon induced with helicase C domain 1 (IFIH1), interferon regulatory factor 7 (IRF7), DExD/H box helicase 58 (DDX58) and interferon-stimulating gene 15 (ISG15) were detected to be hub genes based on the protein-protein interactions and six topological algorithms. A key module involved in influenza A, the Toll-like receptor signaling pathway, was identified using Cytoscape software. The hub genes were regulated by GATA-binding factor 2 and microRNA-146a-5p. In addition, RT-qPCR indicated that the expression levels of the hub genes STAT1 and IFIH1 were low during asthma deterioration compared with post-treatment recovery samples. The present study enhanced the understanding of the mechanism of RV-induced asthma deterioration.

Abstract
Porcine enterovirus G (EV-G) is endogenous to most pig farming countries worldwide. Reports that a papain-like protease (PLP) gene has been naturally inserted into the 2C/3A junction region of the EV-G genome, has increased the potential public health threats from this virus. We constructed a full-length infectious cDNA clone of EV-G, CH/17GXQZ/2017, in order to determine the packaging capacity at the 2C/3A insertion site. Subsequently, recombinants viruses containing the coding tags, GFP, iLOV and His at the 2C/3A junction region, were synthesized. The infectious virus was successfully rescued only with the insertion of the His-tag, which displayed similar virological and molecular properties to its parental strain. This study determined the packaging capacity of the 2C/3A insertion site, and it provides a practical tool for studying the functions and pathogenic mechanisms of EV-G in pigs.

Abstract
Coxsackievirus A5 (CV-A5) is a re-emerging enterovirus that causes hand, foot, and mouth disease in children under five years of age. CV-A5-M14-611 is a mouse-adapted strain that can infect orally and lead to the death of 14-day-old mice. Here, recombinants based on CV-A5-M14-611 were constructed carrying three reporter genes in different lengths. Smaller fluorescent marker proteins, light, oxygen, voltage sensing (iLOV), and nano luciferase (Nluc) were proven to be able to express efficiently in vitro. However, the recombinant with the largest insertion of the red fluorescence protein gene (DsRed) was not rescued. The construction strategy of reporter viruses was to insert the foreign genes between the C-terminus of VP1 and the N-terminus of 2A genes and to add a 2A protease cleavage domain at both ends of the insertions. The iLOV-tagged or Nluc-tagged recombinants, CV-A5-iLOV or CV-A5-Nluc, exhibited a high capacity for viral replication, genetic stability in cells and pathogenicity in mice. They were used to establish a rapid, inexpensive and convenient neutralizing antibody assay and greatly facilitated virus neutralizing antibody titration. Living imaging was performed on mice with CV-A5-Nluc, which exhibited specific bioluminescence in virus-disseminated organs, while fluorescence induced by CV-A5-iLOV was weakly detected. The reporter-gene-tagged CV-A5 can be used to study the infection and mechanisms of CV-A5 pathogenicity in a mouse model. They can also be used to establish rapid and sensitive assays for detecting neutralizing antibodies.

Abstract
According to the American Centers for Disease Control and Prevention, people in all age groups catch two or more “colds” per year, at least half of which are caused by human rhinoviruses. Despite decades of effort, there are no vaccines or drugs against rhinovirus infections and even social distancing measures that were effective in reducing the spread of the pandemic coronavirus, SARS-CoV-2, did not reduce the rate of rhinovirus detection. Fortunately, most rhinovirus strains are naturally attenuated in that they are not associated with serious illness, hospitalization or mortality. Instead, rhinoviruses are one of the most frequent viruses found in nasal swabs of asymptomatic, healthy people. Since rhinovirus infections cannot be avoided, a rational approach would be to engineer them for the benefit of their human hosts. Rhinovirus infections naturally induce robust mucosal and serum immune responses to all virus-expressed proteins. Several replication-competent, human rhinovirus vaccine vectors able to express protective antigens for other pathogens have already been designed and tested in animal models. With this strategy, the inevitable common cold would be able to induce immunity not just to a specific rhinovirus serotype but to other more pathogenic respiratory viruses as well. This article reviews existing rhinovirus vaccine vector technology and describes the characteristics that make live-attenuated rhinoviruses attractive vaccine candidates for SARS-CoV-2 and other pathogenic respiratory viruses in the future.

Abstract
A tagged or reporter astrovirus can be a valuable tool for the analysis of various aspects of the virus life cycle, and to aid in the development of genetically engineered astroviruses as vectors. Here, transposon-mediated insertion mutagenesis was used to insert a 15-nucleotide (nt) sequence into random sites of open reading frame 1a (ORF1a) based on an infectious full-length cDNA clone of porcine astrovirus (PAstV). Five sites in the predicted coiled-coil structures (CC), genome-linked protein (VPg), and hypervariable region (HVR) in ORF1a of the PAstV genome were identified that could tolerate random 15 nt insertions. Incorporation of the commonly used epitope tags, His, Flag, and HA, into four of the five insertion sites permitted the production of infectious viruses and allowed recognition by specifically tagged monoclonal antibodies. The results of immuno-fluorescent assays showed that Flag-tagged ORF1a protein overlapped partially with capsid and ORF2b proteins in the cytoplasm. Improved light-oxygen-voltage (iLOV) gene was also introduced at the insertion sites of CC, VPg, and HVR. Only one viable recombinant reporter PAstV expressing iLOV inserted in HVR was recovered. Biological analysis of the reporter virus showed that it displayed similar growth characteristics, and yet produced less infectious virus particles, when compared with the parental virus. The recombinant virus carrying the iLOV fused with the HVR of ORF1a protein maintained its stability and showed green fluorescence after 15 passages in cell cultures. The resultant fluorescently tagged virus could provide a promising tool for the rapid screening of antiviral drugs as well as allowing the visualization of PAstV infection and replication in living cells.

Abstract
Senecavirus A (SVA) is an emerging picornavirus that has been associated with vesicular disease and neonatal mortality in swine. The construction of SVA virus carrying foreign reporter gene provides a powerful tool in virus research. However, it is often fraught with rescuing a recombinant picornavirus harboring a foreign gene or maintaining the stability of foreign gene in the virus genome. Here, we successfully generated recombinant SVA GD05/2017 viruses (V-GD05-clone) expressing the green fluorescent protein (iLOV), red fluorescent protein (RFP), or NanoLuc luciferase (Nluc). These recombinant viruses have comparable growth kinetics to the parental virus. Genetic stability analysis indicated that V-GD05-iLOV was highly stable in retaining iLOV gene for more than 10 passages, while V-GD05-RFP and V-GD05-Nluc lost the foreign genes in five passages. In addition, high-intensity fluorescent signals were found in the V-GD05-RFP- and V-GD05-iLOV-infected cells by fluorescence observation and flow cytometry analysis, and the luciferase activity assay could quantitatively monitor the replication of V-GD05-Nluc. In order to identify the porcine cell receptor for SVA, anthrax toxin receptor 1 (ANTXR1) was knocked out or overexpressed in the ST-R cells. The ANTXR1 knock-out cells lost the ability for SVA infection, while overexpression of ANTXR1 significantly increased the cell permissivity. These results confirmed that ANTXR1 was the receptor for SVA to invade porcine cells as reported in the human cells. Overall, this study suggests that these SVA reporter viruses will be useful tools in elucidating virus pathogenesis and developing control measures. KEY POINTS: • We successfully generated SVA viruses expressing the iLOV, RFP, or Nluc. • The iLOV was genetically stable in the V-GD05-iLOV genome over ten passages. • ANTXR1 was the receptor for SVA to invade porcine cells.

Abstract
Senecavirus A (SVA), also known as Seneca Valley virus, is an emerging virus that causes vesicular disease in pigs. This virus belongs to the genus Senecavirus in the family Picornaviridae. The SVA CH-LX-01-2016 was isolated from Guangdong Province of China in 2016. In this study, a recombinant SVA CH-LX-01-2016 was constructed using reverse genetics, and proven to be able to express efficiently an enhanced green fluorescent protein (eGFP) in vitro. This eGFP-tagged recombinant SVA (rSVA-eGFP) exhibited a high capacity for viral replication. Its fluorescence-tracked characteristics greatly facilitated both virus neutralization test (VNT) and antiviral assay. The rSVA-eGFP-based VNT was used to detect eight porcine serum samples, out of which four were determined to be neutralization titer-positive. Subsequently, two antiviral drugs, ribavirin and apigenin, were assayed for evaluating both effects against the rSVA-eGFP in vitro. The result showed that only the ribavirin exhibited an anti-SVA activity.

Abstract
Background Rhinovirus (RV) causes the common cold and asthma exacerbations. The RV genome is a 7.3 kb single‐strand positive‐sense RNA. Objective Using minor group RV1A as a backbone, we sought to design and generate a recombinant RV1A accommodating fluorescent marker expression, thereby allowing tracking of viral infection. Method Recombinant RV1A infectious cDNA clones harboring the coding sequence of green fluorescent protein (GFP), Renilla luciferase, or iLOV (for light, oxygen, or voltage sensing) were engineered and constructed. RV‐infected cells were determined by flow cytometry, immunohistochemistry, and immunofluorescence microscopy. Results RV1A‐GFP showed a cytopathic effect in HeLa cells but failed to express GFP or Renilla luciferase due to deletion. The smaller fluorescent protein construct, RV1A‐iLOV, was stably expressed in infected cells. RV1A‐iLOV expression was used to examine the antiviral effect of bafilomycin in HeLa cells. Compared to parental virus, RV1A‐iLOV infection of BALB/c mice yielded a similar viral load and level of cytokine mRNA expression. However, imaging of fixed lung tissue failed to reveal a fluorescent signal, likely due to the oxidation and bleaching of iLOV‐bound flavin mononucleotide. We therefore employed an anti‐iLOV antibody for immunohistochemical and immunofluorescence imaging. The iLOV signal was identified in airway epithelial cells and CD45+ CD11b+ lung macrophages. Conclusions These results suggest that RV1A‐iLOV is a useful molecular tool for studying RV pathogenesis. The construction strategy for RV1A‐iLOV could be applied to other RV serotypes. However, the detection of iLOV‐expressing RV in fixed tissue required the use of an anti‐iLOV antibody, limiting the value of this construct.
