Assessing a compound's activity, not just its structure, could accelerate drug discovery

Assessing a drug compound by its activity, not simply its structure, is a new approach that could speed the search for COVID-19 therapies and reveal more potential therapies for other diseases.

This action-based focus - called biological activity-based modeling (BABM) - forms the core of a new approach developed by National Center for Advancing Translational Sciences (NCATS) researchers and others.

Arthritis drugs may reduce mortality and time in ICU for sickest COVID patients

Treating critically ill COVID-19 patients with drugs typically used for rheumatoid arthritis may significantly improve survival, a landmark study has found.

The findings, which were announced in January and have now been peer-reviewed and published in the New England Journal of Medicine, come from the REMAP-CAP trial, which evaluates the effect of treatments on a combination of survival and length of time patients need support in an intensive care unit (ICU).

Real-world effectiveness of COVID-19 vaccine

The Clalit Research Institute, in collaboration with researchers from Harvard University, analyzed one of the world's largest integrated health record databases to examine the effectiveness of the Pfizer vaccine against COVID-19. The study provides the first large-scale peer-reviewed evaluation of the effectiveness of a COVID-19 vaccine in a nationwide mass-vaccination setting. The study was conducted in Israel, which currently leads the world in COVID-19 vaccination rates.

Researchers reveal genetic predisposition to severe COVID-19

HSE University researchers have become the first in the world to discover genetic predisposition to severe COVID-19. The results of the study were published in the journal Frontiers in Immunology.

T-cell immunity is one of the key mechanisms used by the human body to fight virus infections. The staging ground for cell immunity development is the presentation of virus peptides on the surface of infected cells.

Researchers discover potential new therapeutic targets on SARS-CoV-2 Spike protein

The COVID-19 pandemic has prompted considerable investigation into how the SARS-CoV-2 Spike protein attaches to a human cell during the infection process, as this knowledge is useful in designing vaccines and therapeutics. Now, a team of scientists has discovered additional locations on the Spike protein that may not only help to explain how certain mutations make emerging variants more infectious but also could be used as additional targets for therapeutic intervention.

Antibody response may drive COVID-19 outcomes

COVID-19, the source of the current pandemic, may be caused by a single virus, but it has a variety of presentations that make treatment difficult. Children, for example, almost exclusively experience mild or asymptomatic COVID-19, while adults can develop severe or even fatal COVID-19.

Could a nasal spray prevent coronavirus transmission?

A nasal antiviral created by researchers at Columbia University Vagelos College of Physicians and Surgeons blocked transmission of SARS-CoV-2 in ferrets, suggesting the nasal spray also may prevent infection in people exposed to the new coronavirus, including recent variants.
