Discovery opens new possibilities for treating COVID-19 by disrupting virus’ ability to bind the carbohydrate, potentially by using a repurposed drug. Researchers discovered that the SARS-CoV-2 virus can’t grab hold of cell receptor ACE2 without a carbohydrate called heparan sulfate, which is also found on lung cell surfaces – disrupting that interaction with a repurposed drug may help treat COVID-19.

A molecule known as ACE2 sits like a doorknob on the outer surfaces of the cells that line the lungs...

However, the effect of the vaccine specifically against COVID-19 has not been demonstrated. The BCG vaccine, an old treatment originally developed for tuberculosis, has a broad, stimulating effect on the immune system. This gives it an effective preventive action against various infections — possibly also against COVID-19. It is frequently given to children, but in this double-blind randomized clinical study, a collaboration between Radboud University Medical Center and the National and Kapodistrian University of Athens it was shown that elderly people also benefit from it. The results of the study are in Cell.

Physicists at the University of Göttingen, together with pathologists and lung specialists at the Medical University of Hannover, have developed a 3D imaging technique that enables h...

As the world awaits vaccines to bring the COVID-19 pandemic under control, UC San Francisco scientists have devised a novel approach to halting the spread of SARS-CoV-2, the virus that causes the disease.

Led by UCSF graduate student Michael Schoof, a team of researchers engineered a completely synthetic, production-ready molecule that straitjackets the crucial SARS-CoV-2 machinery that allows the virus to infect our cells...
