Abstract
Norovirus (NoV) is an enteric pathogen notorious for causing epidemics of acute gastroenteritis. An effective vaccine against NoV is therefore urgently needed. A short double-stranded RNA (dsRNA) has been described that acts as a retinoic-acid-inducible gene-I agonist to induce the production of type I interferon; it also exhibits adjuvant activity. Using built-in dsRNA of different lengths (DS1 and DS2), we developed a recombinant adenovirus 5 (rAd5) expressing NoV VP1, and evaluated its immunogenicity following oral administration in a mouse model. An in vitro study demonstrated that the dsRNA adjuvants significantly enhanced VP1 protein expression in infected cells. The oral administration of both rAd5-VP1-DS vaccines elicited high serum levels of VP1-specific IgG and blocking antibodies, as well as strong and long-lasting mucosal immunity. There was no apparent difference in immunostimulatory effects in immunised mice between the two dsRNA adjuvants. This study indicates that an oral NoV-rAd5 vaccine with a built-in dsRNA adjuvant may be developed to prevent NoV infection in humans.

Abstract
Although cyclic GMP-AMP synthase (cGAS)-stimulator of interferon genes (STING) signaling has been well recognized in defending DNA viruses, the role of cGAS-STING signaling in regulating infection of RNA viruses remains largely elusive. Noroviruses, as single-stranded RNA viruses, are the main causative agents of acute viral gastroenteritis worldwide. This study comprehensively investigated the role of cGAS-STING in response to murine norovirus (MNV) infection. We found that STING agonists potently inhibited MNV replication in mouse macrophages partially requiring the JAK/STAT pathway that induced transcription of interferon (IFN)-stimulated genes (ISGs). Loss- and gain-function assays revealed that both cGAS and STING were necessary for host defense against MNV propagation. Knocking out cGAS or STING in mouse macrophages led to defects in induction of antiviral ISGs upon MNV infection. Overexpression of cGAS and STING moderately increased ISG transcription but potently inhibited MNV replication in human HEK293T cells ectopically expressing the viral receptor CD300lf. This inhibitory effect was not affected by JAK inhibitor treatment or expression of different MNV viral proteins. Interestingly, STING but not cGAS interacted with mouse RIG-I, and attenuated its N-terminus-mediated anti-MNV effects. Our results implicate an essential role for mouse cGAS and STING in regulating innate immune response and defending MNV infection. This further strengthens the evidence of cGAS-STING signaling in response to RNA virus infection.

Abstract
Human noroviruses (HuNoVs) are increasingly becoming the main cause of transmissible gastroenteritis worldwide, with hundreds of thousands of deaths recorded annually. Yet, decades after their discovery, there is still no effective treatment or vaccine. Efforts aimed at developing vaccines or treatment will benefit from a greater understanding of norovirus-host interactions, including the host response to infection. In this review, we provide a concise overview of the evidence establishing the significance of type I and type III interferon (IFN) responses in the restriction of noroviruses. We also critically examine our current understanding of the molecular mechanisms of IFN induction in norovirus-infected cells, and outline the diverse strategies deployed by noroviruses to supress and/or avoid host IFN responses. It is our hope that this review will facilitate further discussion and increase interest in this area.

Bovine viral diarrhea virus NS4B protein interacts with 2CARD of MDA5 domain and negatively regulates the RLR-mediated IFN-β production. Virus Res 2021; 302:198471.

Abstract
Bovine viral diarrhea virus (BVDV) is an important member of the family Flaviviridae and often causes immunosuppression. Previous studies have suggested that BVDV envelope protein Erns and the nonstructural autoprotease Npro can inhibit host innate immune responses. Herein, we found that BVDV NS4B, as a nonstructural protein necessary for replication, is involved in antagonizing the main RNA virus sensing pathway. Overexpression of BVDV NS4B protein significantly inhibited Sendai virus (SeV)-induced interferon-β promoter activity, IFN-β mRNA and IFN regulatory factor 3 (IRF3) phosphorylation levels. We also discovered that BVDV NS4B protein significantly inhibited RIG-I like receptor (RLRs)-mediated interferon-β (IFN-β) promoter activity and endogenous MDA5 mRNA levels. In addition, the BVDV NS4B protein directly interacts with N-terminal CARDs of MDA5, and co-localized with MDA5 or MDA5-2CARD in the cytoplasm. In summary, the results of this study indicate that the BVDV NS4B protein acts as an interferon-β antagonist through inhibiting the MDA5-mediated signal transduction pathway. Our study provides an in-depth understanding of the molecular mechanisms of BVDV evading the host's natural immune response.
