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.

Study shows oxidant hydrogen peroxide can actually slow down cell ageing

At high concentrations, reactive oxygen species - known as oxidants - are harmful to cells in all organisms and have been linked to ageing.

Ground-breaking discovery provides new insight into how proteins operate

A ground-breaking discovery by Centenary Institute scientists has provided new understanding as to the nature of proteins and how they exist and operate in the human body.

An analysis of genetic diversity of D614G mutation in SARS-CoV-2

A new study published in the preprint server bioRxiv in November 2020 reports that the effect of the mutation is minimal, in terms of pathogenicity or altered response to neutralizing antibodies elicited against the native virus strain.

D614G mutation enhances stability of SARS-CoV-2 spike protein

A new study, published on the preprint server bioRxiv in November 2020 by researchers at the Indian Institute of Science, has explored this issue further. The researchers have found that this mutation is associated with structural and energetic changes that cause this spike variant to become more available during infection, thus rendering the associated strain more infective.

SARS-CoV-2 mutations becoming more contagious

A team of researchers working with Scott Wesley Long from Houston Methodist Hospital and colleagues from Texas, New York, and Illinois studied the patterns of genetic mutations of SARS CoV-2 and its impact on the second wave of infections worldwide.

Adaptive evolution of human coronaviruses may necessitate frequent reformulation of vaccines

Researchers from the Vaccine and Infectious Disease Division at the Fred Hutchinson Cancer Research Center, USA, have revealed that adaptive evolution in the antigenic regions facilitates seasonal coronaviruses to escape the host immune responses and to cause recurrent infections.

Rapid generation of divergent synthetic antibodies against SARS-CoV-2 in a cell-free engineering platform

In a groundbreaking bioRxiv paper, a research group from the Massachusetts Institute of Technology (MIT), Harvard University and Howard Hughes Medical Institute in the US engineered antibodies against the receptor-binding domain (RBD) of the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) spike glycoprotein by using a novel approach. In doing so, they also identified more than 800 predicted binder families.

Researchers use new approach to study the mechanisms of cellular uptake of amyloid beta

One of the hallmarks of Alzheimer's disease is the formation of amyloid plaques--sticky clumps of a protein called amyloid beta--that collect between neurons in the brain.

5-amino levulinic acid inhibits SARS-CoV-2 infection in vitro

Researchers tested 5-amino levulinic acid in vitro in human-derived cells and found it prevents severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection. Because it is safe and ubiquitous in plants and animals, it could be a potential drug against SARS-CoV-2.

SARS-CoV-2 viroporin triggers NLRP3 inflammasome causing a severe inflammatory response

Now, a team of researchers at the University of Florida report that the SARS-CoV-2 viroporin triggers the NLR Family Pyrin Domain Containing 3 (NLRP3) inflammasome, which is responsible for the inflammatory pathology in severely ill COVID-19 patients.
