Genetic modification in ‘coat’ of fatal brain virus may allow it to escape antibodies

A genetic modification in the 'coat' of a brain infection-causing virus may allow it to escape antibodies, according to Penn State College of Medicine researchers.

Mosaic RBD nanoparticles elicit neutralizing antibodies against SARS-CoV-2

The researchers show that the mice immunized with homotypic or mosaic nanoparticles produced broad binding and neutralizing responses, in contrast to plasma antibodies elicited in humans by SARS-CoV-2 infection. The RBD nanoparticles induced cross-reactive IgG responses in the immunized mice.

Altered gut microbiota increases production of molecules that may contribute to type 2 diabetes

It is the bacterial changes in the gut that increase the levels of imidazole propionate, the molecule that makes the body's cells resistant to insulin in type 2 diabetes. This result emerges from a European study, MetaCardis.

"Escape mutations" could help SARS-CoV-2 evade immune attack

Researchers in the United States have identified mutations within severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) – the agent that causes coronavirus disease 2019 (COVID-19) – that can reduce antibody binding to the virus, potentially mediating its escape from immune attack.

Severe COVID-19 complications linked to gut barrier breakdown

A new study claims that severe COVID-19 is caused by a positive feedback loop triggered by systemic inflammation and mediated by abnormal gut permeability. This finding could potentially help open up new avenues of treatment.

Metabolic biomarkers could predict COVID-19 severity

A new study suggests that metabolic biomarkers could possibly predict the severity of COVID-19 in patients.

Research provides insight into how Alzheimer’s plaques form

We are beginning to better understand how 'amyloid-β' protein plaques form, which are implicated in degenerative brain diseases including Alzheimer's and Parkinson's diseases.

Novel mutations in SARS-CoV-2 may explain high pathogenicity of COVID-19

Researchers in Korea and the United States have identified novel genetic variants that demonstrate the active mutational progression of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) – the agent that causes coronavirus disease 2019 (COVID-19).

Antimalarials could disrupt SARS-CoV-2’s Nsp1 translation termination

A research team from the Engelhardt Institute of Molecular Biology in Russia have shown that Nsp1 – a non-structured protein present in the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) pathogen – stimulates translation termination in the stop codon recognition stage. Studying and developing drugs that compete with Nsp1 for binding with the termination complex could therefore be a potential strategy for fighting against coronavirus disease 2019 (COVID-19).

Rhesus monkeys and cats potential spillover reservoirs for COVID-19 virus

A team of researchers from Switzerland, Costa Rica and Germany has conducted a study showing which animal species could potentially serve as spillback reservoirs of severe acute repertory syndrome coronavirus 2 (SARS-CoV-2) – the agent that causes coronavirus disease 2019 (COVID-19).

Biologists investigate how molecular chaperones dissolve protein aggregates linked to Parkinson's

In many neurodegenerative diseases like Parkinson's, protein aggregates form in the brain and are assumed to contribute to neuronal cell death.

Study: Effect of diabetes medication can be blocked by a molecule from gut bacteria

The action of metformin, the classic drug used to treat diabetes by stabilizing blood sugar, can be blocked by a molecule from the bacteria in our intestines, a University of Gothenburg study shows.

Targeting TAAR5 can provide a new treatment opportunity for neurodegenerative disorders

St Petersburg University researchers, led by Professor Raul R. Gainetdinov, Director of the Institute of Translational Biomedicine and Academic Supervisor of the St Petersburg University Hospital, have found a new role for recently discovered neurotransmitter system that uses the trace amine-associated receptor 5 (TAAR5) for neurotransmission.

ERC Synergy project explores causes of drug tolerance in intractable fungal infections

Over the next six years, research groups at Charité - Universitätsmedizin Berlin and Tel Aviv University will study how invasive fungal pathogens are able to evade treatments and develop tolerance to antifungal drugs.

New biomaterial significantly reduces scar formation following wounds

Researchers at UCLA, Duke University and other collaborating institutions have developed a biomaterial that may significantly reduce scar formation after wounding, leading to more effective skin healing.

Promising yeast-expressed SARS-CoV-2 vaccine candidate effective in mice

Researchers at the Texas Children's Hospital Center for Vaccine Development, USA, have published a report on the preprint server bioRxiv that describes a yeast-expressed severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) receptor-binding domain (RBD) protein, a key target of current vaccine development efforts.

Majority of population likely has pre-existing immunity to SARS-CoV-2, claim researchers

A team of researchers has conducted a study suggesting that the majority of the global population is likely to have pre-existing T-cell immunity to severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) – the agent responsible for the coronavirus disease 2019 (COVID-19) pandemic.

Immune-evading variants can emerge in SARS-CoV-2, researchers warn

An international team of researchers has shown that a mutation within severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) – the agent responsible for the coronavirus disease 2019 (COVID-19) – enables the pathogen to evade antibody-mediated immunity while maintaining replication fitness and increasing viral loads.
