Unlocking SARS-CoV-2's Deadly Immune Response

Researchers have made a significant discovery about how the immune system fights the COVID-19 virus. They found that a key way the immune system kills infected cells is through a process called antibody-dependent cellular cytotoxicity (ADCC), where antibodies bind to the virus and then trigger the immune cells to destroy it. The study analyzed 142 different antibodies that target the COVID-19 virus and found that the part of the antibody that binds to the virus is the most important factor in determining how well it can trigger ADCC. This new understanding could lead to better vaccine designs and the development of more effective treatments.
