The COVID-19 pandemic has prompted considerable investigation into how the SARS-CoV-2 Spike protein attaches to a human cell during the infection process, as this knowledge is useful in designing vaccines and therapeutics. Now, a team of scientists has discovered additional locations on the Spike protein that may not only help to explain how certain [...]
Scientists have developed protein fragments—called peptides—that fit snugly into a groove on the SARS-CoV-2 Spike protein that it would normally use to access a host cell. These peptides effectively trick the virus into "shaking hands" with a replica rather than with the actual protein on a cell's surface that lets the virus in. Previous research has determined that the novel coronavirus [...]
HSE University researchers have become the first in the world to discover genetic predisposition to severe COVID-19. The results of the study were published in the journal Frontiers in Immunology. T-cell immunity is one of the key mechanisms used by the human body to fight virus infections. The staging ground for cell immunity development is [...]
When SARS-CoV-2 first began spreading across the globe, not every lab was equipped to study it directly. The virus behind the current pandemic is highly pathogenic and transmissible, leading the US Centers for Disease Control and Prevention to require many of the same biosafety guidelines that shape the study of diseases such as tuberculosis and Ebola. [...]
esearchers have detailed a mechanism in the distinctive corona of Covid-19 that could help scientists to rapidly find new treatments for the virus, and quickly test whether existing treatments are likely to work with mutated versions as they develop. The team, led by the University of Warwick as part of the EUTOPIA community of [...]
Almost half of people testing positive for coronavirus have reported symptoms of depression, according to a new study published in the International Journal of Environmental Research and Public Health. Researchers from Bangladesh, the United States and Anglia Ruskin University (ARU) in the UK carried out a cross-sectional survey of more than 1,000 Bangladeshi adult coronavirus [...]
A team of investigators from the Republic of China has discovered that 6 drugs previously approved by the US Food and Drug Administration (FDA) for other indications could be repurposed to treat or prevent COVID-19. The research is published in Antimicrobial Agents and Chemotherapy, a journal of the American Society for Microbiology. Using FDA-approved drugs [...]
Graphene is a layer of carbon only one atom thick. Since it was first isolated in 2004, it has found applications in strengthening materials, accelerating electronics, and boosting performance in batteries, among others. It also shows great potential for use in biosensors. These are devices used to detect small concentrations of biomarkers in biological [...]
Another Covid variant that could dodge vaccine-triggered immunity has been identified in the UK, scientists say. The strain — called B.1.525 — has been spotted 33 times already but experts say this could be an underestimate. It carries the E484K mutation found on both the South African and Brazilian variants, which make the current [...]
The ongoing Covid-19 pandemic has yielded an unexpected advancement in the pharmaceutical industry with the approval of the first mRNA vaccines, which GlobalData expects will soon impact other indications. This historical landmark could have significant implications, primarily in the oncology market since mRNA vaccines were being exclusively investigated in infectious and oncology diseases prior [...]
