Scientists identify antibody 'SC27' to counter all Covid-19 variants | sciencefather.com

 Researchers have discovered an antibody that could counter all known variants of the coronavirus that causes COVID-19 and also distantly related ones that infect other animals.

SARS-CoV-2, the coronavirus causing COVID-19, ScienceFather uses its spike protein to invade and infect another individual, or the host. Antibodies, produced by the host in response, bind to the spike protein to block its action and prevent infection.

The researchers, led by those at The University of Texas in Austin, US, isolated the antibody 'SC27' from the plasma donated by four patients. ScienceFather These patients had breakthrough infections, which occur when a vaccinated individual gets infected.


The research has been published in the journal Cell Reports Medicine.
Over the more than four years since the first case of COVID-19 emerged, SARS-CoV-2 has evolved to acquire certain characteristics which make the virus resistant to vaccines and treatments.ScienceFather
The authors said the 'SC27' antibody recognised all these various characteristics of the spike proteins across COVID-19 variants.

"One goal of this research, and vaccinology in general, is to work toward a universal vaccine that can generate antibodies and create an immune response with broad protection to a rapidly mutating virus," said one of the lead authors William Voss, a PhD graduate in cell and molecular biology at The University of Texas.

Words Matter When Discussing Alcohol Issues: A New Stigma-Free Vocabulary for Better AUD Outcomes

Image
Word choice may seem out of place among the myriad factors that can influence outcomes for a complex condition like alcohol use disorder (AUD). In fact, the stigma created by the language that is used to describe alcohol problems can decrease many people’s willingness to seek help for alcohol problems. It also can affect how people with AUD are treated in all aspects of life. “Stigmas are the negative attitudes toward people that are based on certain distinguishing characteristics,” says National Institute on Alcohol Abuse and Alcoholism (NIAAA) Director George F. Koob, Ph.D. “More than a decade of research has shown that stigma contributes significantly to negative health outcomes and can pose a barrier to seeking treatment for mental illness or substance use disorders.” In the United States, nearly 90 percent of people with substance use disorders and 35 percent of people with serious mental illness do not receive treatment. In a recent article published in  Neuropsychopharma...

‘Massive-scale mobilization’ necessary for addressing climate change, scientists say

Image
A year after a global coalition of more than 11,000 scientists declared a climate emergency, Oregon State University researchers who initiated the declaration released an update today that points to a handful of hopeful signs, but shares continued alarm regarding an overall lack of progress in addressing climate risks. “Young people in more than 3,500 locations around the world have organized to push for urgent action,” said Oregon State University’s William Ripple, who co-authored “The Climate Emergency: 2020 in Review,” published today in Scientific American. “And the Black Lives Matter movement has elevated social injustice and equality to the top of our consciousness. “Rapid progress in each of the climate action steps we outline is possible if framed from the outset in the context of climate justice – climate change is a deeply moral issue. We desperately need those who face the most severe climate risks to help shape the response.” One year ago, Ripple, distinguished profess...

Researchers advance science behind gut health and prebiotics

Image
When it comes to improving human gut health, approaches and the success of these approaches are based largely on an individual’s gut ecosystem: the bacteria present, its diversity and other factors. Therefore, trying to improve gut health through application of prebiotics or probiotics can have wildly variable results based on gut flora composition. Bruce Hamaker , director of the Whistler Center for Carbohydrate Research and Distinguished Professor of Food Science, and Thaisa Moro Cantu-Jungles, his postdoctoral research associate, recently discovered a way to select prebiotic fibers that have the potential to provide improvement of gut health where everyone would benefit. Their study, conducted in vitro, showed an increase in butyrate-producing bacteria with a selected fiber using this new approach. Butyrate is a short-chain fatty acid that supports many of the body’s essential functions from regulating the immune system to digestive health. In donors’ gut flora where these bacter...
