Enhanced protective efficacy of a dendritic cell-targeting truncated F protein delivery via minicircle DNA vaccine against genotype VII newcastle disease virus in chickens.

Newcastle disease (ND), caused by the Newcastle disease virus (NDV), poses a severe threat to global poultry farming, leading to significant losses annually. The limitations of current ND vaccines in terms of efficacy and duration of protection have encouraged the exploration of novel vaccine designs. This study aimed to adopt a delayed-lysis Salmonella strain χ11218 as vaccine delivery vector.

Faecalibacterium prausnitzii-derived outer membrane vesicles reprogram gut microbiota metabolism to alleviate Porcine Epidemic Diarrhea Virus infection.

Background: The Porcine Epidemic Diarrhea Virus (PEDV) is one of the major challenges facing the global pig farming industry, and vaccines and treatments have proven difficult in controlling its spread. Faecalibacterium prausnitzii (F.prausnitzii), a key commensal bacterium in the gut, has been recognized as a promising candidate for next-generation probiotics due to its potential wide-ranging health benefits.

The glycosylation sites in RBD of spike protein attenuate the immunogenicity of PEDV AH2012/12.

Porcine epidemic diarrhea (PED) is a highly contagious swine intestinal disease caused by PED virus (PEDV). Vaccination is a promising strategy to prevent and control PED. Previous studies have confirmed that glycosylation could regulate the immunogenicity of viral antigens.

African swine fever virus MGF505-7R protein interacted with IRF7and TBK1 to inhibit type I interferon production.

African swine fever virus (ASFV) employs diverse strategies to confront or evade host type I interferon (IFN-I)-induced antiviral responses. Moreover, the mechanisms of this process are largely unknown. Here, we assessed 27 ASFV proteins to determine whether any of them suppressed the cGAS-STING pathway to facilitate immune evasion.

African swine fever virus MGF360-11L negatively regulates cGAS-STING-mediated inhibition of type I interferon production.

The type I interferon (IFN-I) signaling pathway is an important part of the innate immune response and plays a vital role in controlling and eliminating pathogens. African swine fever virus (ASFV) encodes various proteins to evade the host's natural immunity. However, the molecular mechanism by which the ASFV-encoded proteins inhibit interferon production remains poorly understood.

The CpG Dinucleotide Adjacent to a κB Site Affects NF-κB Function through Its Methylation.

NF-κB is an important transcription factor that plays critical roles in cell survival, proliferation, inflammation, and cancers. Although the majority of experimentally identified functional NF-κB binding sites (κB sites) match the consensus sequence, there are plenty of non-functional NF-κB consensus sequences in the genome. We analyzed the surrounding sequences of the known κB sites that perfectly match the GGGRNNYYCC consensus sequence and identified the nucleotide at the -1 position of κB sites as a key contributor to the binding of the κB sites by NF-κB.
