UAB - The University of Alabama at Birmingham, 2023 The University of Alabama at Birmingham. When an antibody binds to the cell, it serves as a flag to attract disease-fighting molecules or as a trigger that promotes cell destruction by other immune system processes. Now, doctors are using that same technology to develop monoclonal antibodies to target the coronavirus.
