Researchers at Laussane University hospital discover a highly effective antibody against SARS-CoV-2

 

A newly discovered antibody was isolated from the lymphocytes of patients with COVID-19. These patients were enrolled in a research study conducted by Laussane University Hospital. This antibody has been found to be very powerful in fighting against SARS-CoV-2. After performing structural analysis of the antibody, the researchers found that it does not associate itself with mutations of the spiked protein.

The cells expressing the ACE2 receptor are prevented from binding to the spike protein by the newly discovered antibody. The COVID-19 virus uses the spike protein to enter the body and infect the cells of the lungs. This implies that the antibody fights against the replication of the virus, helping immune cells in eliminating SARS-CoV-2 from the human body.

In vivo tests confirmed the antiviral properties of the antibody, which was administered into some specimens that had contracted a high infection of the virus. This antibody offers a lasting effect of protection against coronavirus infection. In general, a conventional antibody can provide protection against infection for about 3-4 weeks.

But this antibody offers protection for about 4-6 months, making it an attractive treatment that prevents infection in unvaccinated people or in vaccinated people with compromised immunity. These patients, cancer patients, or those who have undergone organ transplantation in these times should receive at least two to three doses of antibody injections in a year. The clinical trial of the drug containing this new antibody would begin in the latter half of the year 2022.

In Europe, a lot of efforts have been made in drug discovery, especially in times of COVID-19 pandemic. This newly discovered antibody can be very effective in fighting COVID-19 infection. This new form of treatment should be made available in the form of a drug, enhancing protection of patients with weak immune systems. However, it may be noted that the antibody cannot be replacement to COVID-19 vaccines, which are still most effective in controlling the pandemic.
