Study shows how dietary saturated/trans fats promote liver tumorigenesis

Fatty foods harm our health. Prior research has established a link between the consumption of dietary fats and non-alcoholic fatty liver disease, which subsequently leads to inflammation and tumor formation in the liver. However, the precise effects of dietary fat composition on liver tumorigenesis remain elusive. A new study shows that dietary saturated/trans fats, but … Read more

Research reveals a novel viral strategy in modulating stress granule formation to promote virus infection

In a recent study published in PLOS pathogensresearchers illustrated a novel strategy likely employed by viruses to promote infection. Study: Targeting Nup358/RanBP2 by a viral protein disrupting stress granule formation. Image credit: Rost9/Shutterstock Background Viruses likely inhibit a host cell stress response by blocking the accumulation of stress granules (SGs). SGs are ‘sinks’ or ribonucleic … Read more

Pocket feature in SARS-CoV-2 spike protein is present in all deadly coronaviruses, study reveals

Scientists have discovered why some coronaviruses are more likely to cause severe disease, which has remained a mystery until now. Researchers of the University of Bristol-led study, published in Science advances today [23 November], say their findings could lead to the development of a pan-coronavirus treatment to defeat all coronaviruses-; from the 2002 SARS-CoV outbreak … Read more

Research reveals existence of a hidden ”pocket” on the surface of key SARS-CoV-2 protein

With the continuous emergence of new variants and the risk of new strains of the virus, the development of innovative therapies against SARS-CoV-2 remains a major public health challenge. Currently, the proteins that are on the surface of the virus and/or are involved in its replication are the preferred therapeutic targets, such as the spike … Read more

Novel mRNA vaccines encoding monkeypox virus proteins show promise in preclinical studies

In a recent study posted to the bioRxiv* preprint server, researchers in China demonstrated the efficacy of three messenger ribonucleic acid (mRNA) technology-based Monkeypox virus (MPXV) vaccines in combating a lethal Vaccinia virus (VACV) challenge in mice models. Study: Novel mRNA vaccines encoding monkeypox virus M1R and A35R protect mice from a lethal virus challenge. … Read more

The biological properties of the SARS-CoV-2 E protein in the context of HIV-1

In a recent study published in Retrovirologyresearchers assessed the effectiveness of severe acute respiratory syndrome coronavirus (SARS-CoV) and SARS-CoV-2 envelope (E) proteins against human immunodeficiency virus (HIV)-1. Study: The envelope proteins from SARS-CoV-2 and SARS-CoV potently reduce the infectivity of human immunodeficiency virus type 1 (HIV-1). Image Credit: Corona Borealis Studio/Shutterstock Background Viroporins are ion … Read more

Chitin-immobilized nanobodies for SARS-CoV-2 detection

In a recent study posted to bioRxiv*, researchers demonstrated a novel strategy to detect severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) using chitin-immobilized nanobodies. Study: Efficient SARS-CoV-2 detection utilizing chitin-immobilized nanobodies synthesized in Ustilago maydis. Image Credit: CROCOTHERY/Shutterstock Background Shark and Camelidae-derived nanobodies are emerging alternatives to traditional antibodies. Nanobodies bind to ligands at the … Read more

Mosaic nanoparticles displaying spike protein trimers from different coronaviruses elicits cross-reactive protection

In a recent study under review at the Nature Portfolio journal and currently posted to Research Square* preprint server, researchers developed and assessed the immunogenicity of nanoparticles expressing spike trimers from coronaviruses (CoVs). CoVs, particularly beta-CoVs, thrive in animal reservoirs and constantly threaten human health. Seven CoVs infect humans, including severe acute respiratory syndrome coronavirus … Read more

SpyCatcher-SpyTag technology used to develop recombinant protein-based intranasal vaccine against SARS-CoV-2

The findings of a new study posted to the bioRxiv* preprint server showed that the intranasal SpyCage vaccine platform can be protective against severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) and may prove to be a versatile and adaptable modality for the formulation of intranasal vaccines that target respiratory pathogens. Study: Intranasal virus-particle mimicking vaccine … Read more
