ISG15 is a type I interferon (IFN)-inducible gene encoding a protein with pleiotropic functions, acting both as a soluble molecule and as a protein modifier. Surprisingly, and despite the antiviral functions of ISG15 described in mice, humans born with inactivating mutations of ISG15 do not present with any overt viral phenotype, but are highly susceptible to environmental mycobacteria and have autoinflammatory disease presentations. In vitro, ISG15 deficiency also leads to persistently high levels of type I IFN-stimulated gene expression and to increased resistance to all viruses tested to date...

Exosomes are vesicles secreted to the extracellular environment through fusion with the plasma membrane of specific endosomes called multivesicular bodies (MVB) and mediate cell-to-cell communication in many biological processes. Posttranslational modifications are involved in the sorting of specific proteins into exosomes. Here we identify ISGylation as a ubiquitin-like modification that controls exosome release. ISGylation induction decreases MVB numbers and impairs exosome secretion. Using ISG15-knockout mice and mice expressing the enzymatically inactive form of the de-ISGylase USP18, we demonstrate in vitro and in vivo that ISG15 conjugation regulates exosome secretion...

Hepatitis B virus (HBV) is an important account of infectious hepatitis and interferon (IFN) remains one of the best treatment options. Activation of type I IFN signaling pathway leads to expressions of IFN-stimulated genes (ISGs) which play important roles in antiviral and immunomodulatory responses to HBV or hepatitis C virus (HCV) infection. Our previous studies indicated that ISG15 and its conjugation (ISGylation) were exploited by HCV to benefit its replication and persistent infection. This study was designed to assess the role of ISG15 and ISGylation in HBV infection in vitro...

In this study, we constructed for the first time a full-length cDNA clone of pig-original bovine viral diarrhea virus 2 (BVDV-2) strain SH-28, modified the cDNA clone (pASH28) for mutant pASHΔN(pro) and derived virus strain vASHΔN(pro) by deleting the genomic region encoding the N(pro) polypeptide, and examined significance of protein N(pro) for antiviral responses in vitro. Data showed that N(pro)-deletion mutant virus vASHΔN(pro) led to significant overexpression of oligo adenylate synthetase (OAS), myxovirus-resistant protein 1 (Mx1), and ubiquitin-like protein 15 (ISG15)...

Tripartite motif-containing 32 (TRIM32) has been demonstrated to pay vital roles in cancer, genetic disorders and antiviral immunity. However, the molecular functions of fish TRIM32 still remained largely unknown. Here, a novel TRIM32 gene from orange spotted grouper (EcTRIM32) was cloned and characterized. EcTRIM32 encoded a 685-aa protein which showed 93%, and 60% identity to large yellow croaker (Larimichthys crocea) and human (Homo sapiens), respectively. Amino acid alignment showed that EcTRIM32 contained a conserved RING-finger domain, a BBOX domain and NHL domain...

BACKGROUND: Borna disease virus is a neurotropic pathogen and infects the central nervous system. This virus infected a variety of animal species including cows. The most of cows infected with Borna disease virus 1 (BoDV-1) exhibit subclinical infection without any neurological symptoms throughout their lifetime. We previously reported on the low conception rates in-seropositive cows. Interferon-τ (IFN-τ) plays an important role in stable fertilization, and is produced from the fetal side following embryo growth at 15-40 days of pregnancy...

Probiotics are essential for the prevention of virus invasion and the maintenance of the immune balance. However, the mechanism of competition between probiotics and virus are unknown. The objectives of this study were to isolate the surface layer (S-layer) protein from L. acidophilus ATCC 4356 as a new antiviral material, to evaluate the stimulatory effects of the S-layer protein on mouse dendritic cells (DCs) and to verify its ability to inhibit the invasion of H9N2 avian influenza virus (AIV) in DCs. We found that the S-layer protein induced DCs activation and up-regulated the IL-10 secretion...

Pregnancy recognition is associated with the upregulation of the great number of genes in ruminants. One of these genes is interferon-stimulatory gene (ISG15), an ubiquitin-like protein that mediates the conjugation of different proteins through its ISGylation enzymes UBE1L and UBCH8. We demonstrate that ISG15 and its ISGlyation enzymes UBE1L and UBCH8 are differentially regulated in pregnant and non-pregnant cows. The mRNA and/or protein levels of ISG15, UBE1L and UBCH8 increased significantly (p<0.05) after treatment of PBMCs with different concentrations of interferon-tau (IFN-τ)...

The Bowman-Birk inhibitor (BBI), a soybean-derived protease inhibitor, is known to have anti-inflammatory effect in both in vitro and in vivo systems. Macrophages play a key role in inflammation and immune activation, which is implicated in HIV disease progression. Here, we investigated the effect of BBI on HIV infection of peripheral blood monocyte-derived macrophages. We demonstrated that BBI could potently inhibit HIV replication in macrophages without cytotoxicity. Investigation of the mechanism(s) of BBI action on HIV showed that BBI induced the expression of IFN-β and multiple IFN stimulated genes (ISGs), including Myxovirus resistance protein 2 (Mx2), 2',5'-oligoadenylate synthetase (OAS-1), Virus inhibitory protein (viperin), ISG15 and ISG56...

BACKGROUND: Alcohol consumption exacerbates the pathogenesis of hepatitis C virus (HCV) infection and worsens disease outcomes. The exact reasons are not clear yet, but they might be partially attributed to the ability of alcohol to further suppress the innate immunity. Innate immunity is known to be already decreased by HCV in liver cells. METHODS: In this study, we aimed to explore the mechanisms of how alcohol metabolism dysregulates IFNα signaling (STAT1 phosphorylation) in HCV(+) hepatoma cells...

Objectives were to identify cows with embryo mortality (EM) around the period of corpus luteum (CL) maintenance by Interferon tau (IFNT) and characterize ovarian function in cows that underwent EM. Lactating Holstein cows received AI (Day = 0) with semen or extender only. From Day 14 to 42 transrectal ultrasonography was performed daily to monitor ovarian dynamics and uterine contents whereas blood was collected every 48 h to determine ISG15 and MX2 mRNA abundance in blood mononuclear cells (Day 14 to 22 only) and determination of hormone concentrations...

A bovine interferon-kappa (BoIFN-κ) gene was amplified, which encodes a protein of 215 amino acids sharing 63% identity with human IFN-κ. BoIFN-κ was demonstrated to have antiviral and antiproliferative activities. Moreover, BoIFN-κ was shown to be highly sensitive to trypsin, however, it remained stable despite changes in pH and temperature. Result showed that BoIFN-κ can bind with bovine type I IFN receptors, and the antiviral activity can be blocked by antibodies against type I IFN receptors or BoIFN-κ...

Genome-editing technologies allow systematic inactivation of human genes. Whether knockout phenotypes always reflect gene functions as determined by acute RNAi is an important question. Here we show how the acute knockdown of the Adams-Oliver syndrome (AOS) gene DOCK6, coding for a RAC1/CDC42 guanine nucleotide exchange factor, results in strikingly different phenotypes to those generated by genomic DOCK6 disruption. Cell-intrinsic adaptation compensates for loss of DOCK6 function. Prolonged DOCK6 loss impacts upon the MRTF-A/SRF transcription factor, reducing levels of the ubiquitin-like modifier ISG15...

β-Catenin is a major transducer of the Wnt signaling pathway, which is aberrantly expressed in colorectal and other cancers. Previously, we showed that β-catenin is downregulated by the 90K glycoprotein via ISGylation-dependent degradation. However, the further mechanisms of β-catenin degradation by 90K-mediated ISGylation pathway were not investigated. This study aimed to identify the β-catenin domain responsible for the action of 90K and to compare the mechanism of 90K on β-catenin degradation with phosphorylation-dependent ubiquitinational degradation of β-catenin...

Vaccines based on inactivated or attenuated viruses can be a way to prevent viral hemorrhagic septicemia virus (VHSV) disease, and the efficiency of viral production is a critical factor that can determine the practical use of developed vaccines in aquaculture farms. To know the effects of epithelioma papulosum cyprini (EPC) cells over-subculture on VHSV replication, the VHSV titer produced from high-passage EPC cells (subcultured more than 200 times in our laboratory) was compared to the titer produced from low-passage EPC cells (subcultured 5-15 times)...

Interferon-stimulated gene 15 (ISG15) is an important cytokine that has been reported in carcinogenesis. However, we found that ISG15 and de-ISGylase USP18 were induced by several anti-cancer agents, which was confirmed by both RT-PCR and immunoblotting assays. Further studies demonstrated that ectopic ISG15 and USP18 inhibited proliferation of myeloma, leukemia and cervical cancer cells. More importantly, ISG15 and USP18 induced cancer cell apoptosis. This finding was confirmed in a cervical xenograft model in which cervical cancer growth was suppressed by lentiviral ISG15...

The interferon-stimulated gene 15 ubiquitin-like modifier (ISG15) encodes an IFN-inducible, ubiquitin-like protein. The ISG15 protein forms conjugates with numerous cellular proteins that are involved in a multitude of cellular functions, including interferon-induced immune responses and the regulation of cellular protein turnover. The expression of ISG15 and ISG15-mediated conjugation has been implicated in a wide range of human tumors and cancer cell lines, but the roles of ISG15 in tumorigenesis and responses to anticancer treatments remain largely unknown...
