Abstract
mRNA m6A modification is heavily involved in modulation of immune responses. However, its function in antiviral immunity is controversial, and how immune responses regulate m6A modification remains elusive. We here find TBK1, a key kinase of antiviral pathways, phosphorylates the core m6A methyltransferase METTL3 at serine 67. The phosphorylated METTL3 interacts with the translational complex, which is required for enhancing protein translation, thus facilitating antiviral responses. TBK1 also promotes METTL3 activation and m6A modification to stabilize IRF3 mRNA. Type I interferon (IFN) induction is severely impaired in METTL3-deficient cells. Mettl3fl/fl-lyz2-Cre mice are more susceptible to influenza A virus (IAV)-induced lethality than control mice. Consistently, Ythdf1-/- mice show higher mortality than wild-type mice due to decreased IRF3 expression and subsequently attenuated IFN production. Together, we demonstrate that innate signals activate METTL3 via TBK1, and METTL3-mediated m6A modification secures antiviral immunity by promoting mRNA stability and protein translation.

Abstract
Mx proteins are interferon-induced members of the dynamin superfamily of large guanosine triphosphatases. These proteins have attracted much attention because some display antiviral activity against pathogenic RNA viruses, such as members of the orthomyxoviridae, bunyaviridae, and rhabdoviridae families. Among the diverse mammalian Mx proteins examined so far, we have recently demonstrated in vitro that the Bos taurus isoform 1 (boMx1) is endowed with exceptional anti-rabies-virus activity. This finding has prompted us to seek an appropriate in vivo model for confirming and evaluating gene therapy strategies. Using a BAC transgene, we have generated transgenic mouse lines expressing the antiviral boMx1 protein and boMx2 proteins under the control of their natural promoter and short- and long-range regulatory elements. Expressed boMx1 and boMx2 are correctly assembled, as deduced from mRNA sequencing and western blotting. Poly-I/C-subordinated expression of boMx1 was detected in various organs by immunohistochemistry, and transgenic lines were readily classified as high- or low-expression lines on the basis of tissue boMx1 concentrations measured by ELISA. Poly-I/C-induced Madin-Darby bovine kidney cells, bovine turbinate cells, and cultured cells from high-expression line of transgenic mice were found to contain about the same concentration of boMx1, suggesting that this protein is produced at near-physiological levels. Furthermore, insertion of the bovine Mx system rendered transgenic mice resistant to vesicular-stomatitis-virus-associated morbidity and mortality, and embryonic fibroblasts derived from high-expression transgenic mice were far less permissive to the virus. These results demonstrate that the Bos taurus Mx system is a powerful anti-VSV agent in vivo and suggest that the transgenic mouse lines generated here constitute a good model for studying in vivo the various antiviral functions-known and yet to be discovered-exerted by bovine Mx proteins, with priority emphasis on the antirabic function of boMx1.

Abstract
Interferon-gamma (IFN-gamma) has potent antiviral activity in neurons which is affected by the production of nitric oxide (NO). This study examines the interactions between cannabinoid receptor-1 (CB(1)), IFNgamma-induced pathways, and inhibition of vesicular stomatitis virus (VSV) replication in neuronal cells. CB(1) is abundantly expressed in neurons of the CNS and the NB41A3 neuroblastoma cell line. CB(1) activation of NB41A3 cells by the synthetic cannabinoid, WIN55,212-2, is associated with an inhibition of Ca(2+) mobilization, leading to diminished nitric oxide synthase (NOS)-1 activity and the production of NO, in vitro. This ultimately results in antagonism of IFN-gamma-mediated antiviral activity and enhanced viral replication. Therefore, activation of cells expressing CB(1) by endogenous (or exogenous) ligands may contribute to decreased inflammation and to increased viral replication in neurons and disease in the CNS.

Abstract
Melatonin, a potent antioxidant, has shown to be beneficial in murine Venezuelan equine encephalomyelitis (VEE) virus infection. In addition, melatonin can induces the production of interleukin-1 beta (IL-1beta), a cytokine capable of inducing increased expression of inducible nitric oxide synthase; the activity of this enzyme is increased in the brain of mice infected with VEE virus. The aim of this study was to determine the effect of VEE virus on the nitric oxide (NO) production, lipid peroxidation and IL-1beta production in the brain and serum of mice infected with VEE virus, and to investigate the modulatory role of melatonin during this viral infection. Mice were infected with 10 LD(50) of VEE virus and treated with melatonin (500 microg/kg of body weight) starting 3 days before and continuing for 5 days after virus inoculation. Mice were sacrificed on days 1, 3 and 5 postinfection and brains and blood samples were obtained. NO and IL-1beta production and lipid peroxidation levels were measured in perfused brain homogenates and serum. Increased production of brain nitrite was found on days 1, 3 and 5 postinfection and lipid peroxidation products were increased at day 5. Levels of serum nitrite were found elevated on days 3 and 5 postinfection; however, lipid peroxidation products remained similar to basal levels. Melatonin treatment decreased nitrite concentration in brain and serum of infected mice as well as the lipid peroxidation products in the brain. IL-1beta was found to be increased in the brain and serum of infected animals, and melatonin treatment induced higher levels of this cytokine (brain: about 4-fold; serum: about 8-fold). These results may be related to the beneficial effect of melatonin in the VEE experimental disease and address the possible therapeutic potential of the indoleamine in human VEE virus infection.

Abstract
Increased expression of inducible nitric oxide synthase has been shown in murine Venezuelan equine encephalitis (VEE) virus infection. In this experimental model, melatonin (MTL) treatment has shown to be beneficial. The aim of this study was to determine the effect of VEE virus on the nitric oxide (NO) production and lipid peroxidation in neuroblastoma cell cultures, and to investigate the role of MTL during cell-virus interaction. Neuroblastoma cells were co-cultured with VEE virus and treated with MTL at doses ranging from 0 to 1.8 mM, for 6, 12, 24 and 48 h. NO and lipid peroxidation were measured in culture supernatants and in the cellular content by nitrite concentration and thiobarbituric acid assay, respectively. Expression of inducible nitric oxide synthase (iNOS) was determined by indirect immunofluorescence. Increased production of NO and lipid peroxidation products were found in supernatants and cellular contents of VEE virus treated cultures. Both NO and lipid peroxidation were decreased by MTL treatment in a time dependent manner. Increased iNOS expression was observed in VEE virus infected cultures that was reduced by MTL treatment. These results could be related to the beneficial role of MTL in the VEE experimental disease and address the possible therapeutic potential of the hormone in human VEE virus infection.

Abstract
Vesicular stomatitis virus (VSV), a negative-sense, single-stranded RNA rhabdovirus, causes acute viral encephalitis when administered intranasally to mice. Interleukin-12 (IL-12) is a key pro-inflammatory cytokine that is produced largely by the antigen presenting cells (APC) and that bridges the innate and acquired immune responses. IL-12 is efficacious in enhancing recovery from VSV infection of the murine central nervous system. This effect is mediated by nitric oxide (NO) produced by the neuronal isoform of nitric oxide synthase (NOS-1), and is independent of the pro-inflammatory cytokines interferon-gamma (IFN-gamma) and tumor necrosis factor-alpha (TNF-alpha). These data implied a link between IL-12 and NOS-1. Here we investigate the role of the IL-12R during VSV pathogenesis, using IL-12R beta2 and IL-12R beta1-deficient mice. We showed that a deficiency in either IL-12R beta2 or IL-12R beta1 had no effect on the outcome of VSV infection of the CNS or on the clearance of VSV from the CNS. Furthermore, these data indicate that IL-23 is not acting redundantly in the absence of IL-12 during VSV-induced encephalitis.
