Scientists isolate tiny antibody that neutralizes SARS-CoV-2

Researchers are also “thinking outside the box” for how the drug could be administered stating it may be able to be inhaled or through a superficial injection instead of an IV

They isolated the smallest biological molecule, which would help to neutralize the SARS-CoV-2 virus completely.

Ab8, the drug constructed with the antibody fragment, has worked in mice and hamsters, and has the potential eventually to be used as COVID-19 therapy and COVID-19 prevention in humans, according to the news release.

The University of North Carolina at Chapel Hill (UNC), University of Columbia, University of Saskatchewan, and University of Texas Medical Branch (UTMB) already evaluated Ab8's effectiveness.

The component, now developed into a drug called Ab8, was highly effective at treating and preventing SARS-CoV-2 infection in animal models. The drug is seen as a potential preventative against SARS-CoV-2. According to the team, the small size of the biologic not only increases its potential for diffusion into tissues to better neutralise the virus, but also enables administration by alternative routes, including inhalation.

He added that larger antibodies have been effective against other infectious diseases, giving the world a hope that they could also cure and prevent COVID-19 infections.

Wei Li, assistant director of Pitt's Center for Therapeutic Antibodies and co-lead author of the research, sifted through antibody components and found multiple therapeutic antibody candidates in record time.

NM tallies no virus deaths, just 81 cases
The county's website is reporting outcomes in 8,410 cases - where 8,049 are assumed to be recovered and 361 have died. "We know COVID-19 has not been without challenge and loss", said provincial health officer Dr.

It doesn't bind to human cells but only to virus cells thus eliminating any side effects. The tiny antibody component is the variable in the heavy chain (VH) of an immunoglobulin.

It was combined with part of the immunoglobulin tail area to create Ab8, without the bulk of a full-size antibody.

They said the molecule is far smaller than a full-sized antibody, which could allow it to be inhaled or injected just below the skin rather than with standard injection or intravenously, which they said would be another advantage. In the ensuing years, his team discovered potent antibodies against many other infectious diseases, including those caused by MERS-CoV, dengue, Hendra and Nipah viruses. REGN-COV2 is now being studied in two Phase 2/3 clinical trials for the treatment of COVID-19 and in a Phase 3 trial for the prevention of COVID-19 in household contacts of infected individuals. In mice trials, those treated with Ab8 had 10-fold less of the amount of infectious virus compared to those that were untreated.

Scientists discovered a new antibody that could possibly neutralize COVID-19 by preventing it from entering the human cells. They have found this drug to be largely effective in the prevention and treatment of infections.

Mellors says, "The COVID-19 pandemic is a global challenge facing humanity, but biomedical science and human ingenuity are likely to overcome it..."
