The ability of SARS-CoV-2 to infect cells depends on interactions between the viral spike protein and the human cell surface protein ACE2. To enable the virus to hook onto the cell surface, the spike protein binds ACE2 using three finger-like protrusions, called the receptor binding domains (RBDs). Blocking the RBDs therefore has the potential to stop the virus from entering human cells.

Beta-blockers could potentially be used to treat COVID-19, according to a new international study by Italian and Australian scientists.

University of South Australia cancer researcher, Dr Nirmal Robinson, working with a team in Naples, has found evidence in animal models that the beta-blocker Propranolol helps suppress the spread of cancer in the lung which has an inflammatory profile very similar to COVID-19.

An innovative nanoparticle vaccine candidate for the pandemic coronavirus produces virus-neutralizing antibodies in mice at levels ten-times greater than is seen in people who have recovered from COVID-19 infections. Designed by scientists at the University of Washington School of Medicine in Seattle, the vaccine candidate has been transferred to two companies for clinical development.

Researchers from the University of Kent, the Goethe-University in Frankfurt am Main (Germany), and the Hannover Medical School (Germany) have identified a drug with the potential to provide a treatment for COVID-19.

The international team led by Professor Martin Michaelis, Dr Mark Wass (both School of Biosciences, University of Kent), and Professor Jindrich Cinatl (Institute of Medical Virology, Goethe-University) found that

The United States has become the epicenter of the world in the ever increasing pandemic of COVID-19. While public health prevention strategies of social distancing, crowd avoidance, masking and frequent hand washing are of proven benefit, effective drug therapies for treatment are sparse. Not surprisingly, remdesivir has attracted worldwide attention, first receiving an Emergency Use Authorization (EUA) from the U.S. Food and Drug Administration (FDA) and especially with U.S. President Donald Trump taking the drug for COVID-19 earlier this month.

"Much of the discussion so far related to the future trajectory of COVID-19 has rightly been focused on the effects of seasonality and non-pharmaceutical interventions [NPIs], such as mask-wearing and physical distancing," said co-first author Chadi Saad-Roy, a Ph.D. candidate in Princeton's Lewis-Sigler Institute for Integrative Genomics.

The AstraZeneca Oxford COVID-19 vaccine (ChAdOx1 nCoV-19 and also known as AZD1222) now undergoing Phase III clinical trials, has already undergone rigorous testing to ensure the highest standards of quality and safety. Now a team at Bristol University has used recently developed techniques to further validate that the vaccine accurately follows the genetic instructions programmed into it by the Oxford team.
