A team of researchers at the University of Georgia has successfully demonstrated that a set of drug-like small molecules can block the activity of a key SARS-CoV-2 protein - providing a promising path for new COVID-19 therapeutics.

Led by Scott Pegan, director of UGA's Center for Drug Discovery, the team was the first to evaluate the SARS-CoV-2 protein PLpro, known to be essential in

Researchers at the Francis Crick Institute have found that a protein which is initially helpful in the body's immune response to a virus, can later interfere with the repair of lung tissue. The work, published in Science, highlights the need for careful consideration regarding the use of this protein to treat viruses, including coronavirus.

The global effort to quickly develop drugs and vaccines for COVID-19 has been hampered by limited numbers of laboratory mice that are susceptible to infection with SARS-CoV-2, the virus that causes COVID-19. Now, researchers at Washington University School of Medicine in St. Louis report they have developed a mouse model of COVID-19 that replicates the illness in people.

Cancer researchers at Children's Hospital of Philadelphia (CHOP) have harnessed tools used for the development of cancer immunotherapies and adapted them to identify regions of the SARS-CoV-2 virus to target with a vaccine, employing the same approach used to elicit an immune response against cancer cells to stimulate an immune response against the virus.

Early data from a clinical study suggest that blocking the Bruton tyrosine kinase (BTK) protein provided clinical benefit to a small group of patients with severe COVID-19. Researchers observed that the off-label use of the cancer drug acalabrutinib, a BTK inhibitor that is approved to treat several blood cancers, was associated with reduced respiratory distress and a reduction in the overactive immune response in most of the treated patients.

A team of scientists from Stanford University is working with researchers at the Molecular Foundry, a nanoscience user facility located at the Department of Energy's Lawrence Berkeley National Laboratory (Berkeley Lab), to develop a gene-targeting, antiviral agent against COVID-19.

The sacred oath taken by physicians during graduation from medical school to "First do no harm," the first words of the Hippocratic Oath, provides a strong impetus for a commentary just published in The American Journal of Medicine. Researchers from Florida Atlantic University's Schmidt College of Medicine and collaborators from the University of Wisconsin School of Medicine and Public Health are urging all health care providers to always prioritize compassion with reliable evidence on efficacy and safety.
