Pre-existing coronavirus antibodies could help protect children against new pandemic strain

Researchers at the Francis Crick Institute and University College London have found that some antibodies, created by the immune system during infection with common cold coronaviruses, can also target SARS-CoV-2 and may confer a degree of protection against the new viral strain.

In response to infection with a virus, the immune system creates antibodies to help fight it. These antibodies remain in the blood for a period after infection, and in the case of re-infection, they are able to tackle the virus again.

Scientists identify synthetic mini-antibody to combat COVID-19

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.

Cancer treatment could be replicated for COVID-19

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.

Ultrapotent COVID-19 vaccine candidate designed via computer

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.

New drug candidate for the treatment of COVID-19

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

Remdesivir for COVID-19: FDA approved but still unproven

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.

COVID-19 containment shaped by strength, duration of natural, vaccine-induced immunity

"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.
