New small antibodies show promising effects against COVID-19 infection
Researchers at Karolinska Institutet in Sweden have developed, in collaboration with researchers in Germany and the U.S., new small antibodies, also known as nanobodies, which prevent the SARS-CoV-2 coronavirus from entering human cells. The research study, published in Science, shows that a combined nanobody had a particularly good effect – even if the virus mutated. According to the researchers, the nanobodies have the potential to be developed into a treatment for COVID-19.Specific proteins, spike proteins, on the surface of the SARS-CoV-2 coronavirus help the virus infect host cells.
