Porcine deltacoronavirus (PDCoV), a member of genus Deltacoronavirus, is an emerging swine enteropathogenic coronavirus (CoV). Although outstanding efforts have led to the identification Alphacoronavirus and Betacoronavirus receptors, receptor for Deltacoronavirus unclear. Here, we compared amino acid sequences several representative CoVs. Phylogenetic analysis showed that PDCoV spike (S) protein was close cluster containing transmissible gastroenteritis virus (TGEV), which utilizes porcine...
ABSTRACT Rabies, one of the oldest infectious diseases, still presents a public health threat in most parts world today. Its pathogen, rabies virus (RABV), can utilize its viral proteins, such as nucleoprotein and phosphorylation protein, to subvert host innate immune system. For long time, large (L) protein was believed be essential for RABV transcription replication, but role pathogenicity evasion not known. Recent studies have found that conserved K-D-K-E tetrad motif L is related...
Abstract Background The central nervous system (CNS) is vulnerable to viral infection, yet few host factors in the CNS are known defend against invasion by neurotropic viruses. Long noncoding RNAs (lncRNAs) have been revealed play critical roles a wide variety of biological processes and highly abundant mammalian brain, but their defending pathogens into remain unclear. Results We report here that multiple viruses, including rabies virus, vesicular stomatitis Semliki Forest herpes simplex...
One approach for developing a more universal influenza vaccine is to elicit strong immune responses against canonically immunosubdominant epitopes in the surface exposed viral glycoproteins. While standard vaccines typically induce directed primarily mutable hemagglutinin (HA) head domain, there are generally limited or variable relatively conserved HA stalk domain and neuraminidase (NA) proteins. Here we describe that utilizes combination of wildtype (WT) virus particles along with...
Rabies is an ancient disease but remains endemic in most parts of the world and causes approximately 59,000 deaths annually. The mechanism through which causative agent, rabies virus (RABV), evades host immune response infects central nervous system (CNS) has not been completely elucidated thus far. Our previous studies have shown that lab-attenuated, wild-type (wt), RABV activates innate mouse dog models. In this present study, we demonstrate lab-attenuated abortive infection astrocytes,...
Rabies, caused by rabies virus (RABV), is an acute, fatal encephalitic disease that affects many warm-blooded mammals. Currently, post-exposure prophylaxis regimens are effective for most cases, but once the clinical signs of appear, current treatment options become ineffective. Carrageenan has been reported as a potent inhibitor viruses. In this study, λ-carrageenan (λ-CG) P32 was investigated its potential role in inhibiting RABV infection. Our results show specifically inhibits...
ABSTRACT Rabies continues to present a public health threat in most countries of the world. The efficient way prevent and control rabies is implement vaccination programs for domestic animals. However, traditional inactivated vaccines used animals are costly have relatively low efficiency, which impedes their extensive use developing countries. There is, therefore, an urgent need develop single-dose long-lasting vaccines. little information available regarding mechanisms underlying...
Rabies, caused by rabies virus (RABV), is a fatal neurological disease that still causes more than 59,000 human deaths each year. Type III interferon IFN-λs are cytokines with type I IFN-like antiviral activities. Although IFN-λ can restrict the infection for some viruses, especially intestinal inhibitory effect against RABV remains undefined. In this study, function of IFN was investigated. Initially, we found IFN-λ2 and IFN-λ3 could inhibit replication in cells. To characterize role mouse...
Abstract Background Gut microbiome plays a crucial role in modulating human and animal immune responses. Rabies is fatal zoonosis causing encephalitis mammals vaccination the most effective method to control eliminate rabies. The relationship between gut humoral immunity post rabies has not been investigated yet. Methods Mice orally administrated with cocktail of broad‐spectrum antibiotics were inoculated vaccines, response was analyzed at indicated time points. 16S ribosomal RNA (16S rRNA)...
Rabies virus (RABV) causes fatal encephalitis in mammals and poses a public health threat many parts of the world. Vaccination remains most effective means for prevention control rabies. Studies focusing on mechanism RABV immunogenicity are necessary improvement rabies vaccines. Toll-like receptor 7 (TLR7), an innate sensing single-stranded viral RNA, is important induction adaptive immunity. Our studies revealed that absence TLR7 led to lower antibody production mice immunized with RABV. It...
Tripartite motif-containing protein 25 (Trim25) is an E3 ubiquitin ligase that activates retinoid acid-inducible gene I (RIG-I) and promotes the antiviral interferon response. Recent studies have shown Trim25 can bind degrade viral proteins, suggesting a different mechanism of on its effects. In this study, expression was upregulated in cells mouse brains after rabies virus (RABV) infection. Moreover, limited RABV replication cultured cells. Overexpression caused attenuated pathogenicity...
Current seasonal influenza virus vaccines induce responses primarily against immunodominant but highly plastic epitopes in the globular head of hemagglutinin (HA) glycoprotein. Because viral antigenic drift at these sites, need to be updated and readministered annually. To increase breadth vaccine-mediated protection, we developed an antigenically complex mixture recombinant HAs designed redirect immune more conserved domains protein. Vaccine-induced antibodies were disproportionally...
Interferon and its downstream products, ISGs, are essential in defending against pathogen invasion. One of the IIGP1, has been found to constrain intracellular parasite infection by disrupting their vacuole membranes. However, role IIGP1 limiting viral is unclear. In this study, we show that with a typical neurotropic virus, RABV, can induce upregulation which, turn, suppresses RABV interacting phosphoprotein (P protein) thus blocking dimerization P protein. Our study provides first evidence...
Rabies, caused by rabies virus (RABV), is a fatal encephalitis in humans and other mammals, which continues to present public health threat most parts of the world. Our previous study demonstrated that Toll-like receptor 7 (TLR7) essential induction anti-RABV antibodies via facilitation germinal center formation. In study, we investigated role TLR7 pathogenicity RABV mouse model. Using isolated plasmacytoid dendritic cells (pDCs), an innate recognition for RABV. When invaded from periphery,...
ABSTRACT Seasonal influenza vaccines provide mostly strain-specific protection due to the elicitation of antibody responses focused on evolutionarily plastic antigenic sites in hemagglutinin head domain. To direct humoral response toward more conserved epitopes, we generated an virus particle where full-length protein was replaced with a membrane-anchored, “headless” variant while retaining normal complement other viral structural proteins such as neuraminidase well RNAs. We found that...
