In the context of the immune response, what outcome results from antibody-antigen binding?

Antibody-antigen binding results in the marking of pathogens for destruction or neutralization. When antibodies bind to specific antigens on pathogens, such as bacteria or viruses, they serve several critical functions in the immune response. This binding effectively tags the pathogen, facilitating its recognition and elimination by immune cells like macrophages and neutrophils through processes such as opsonization, where the antibody-coated pathogen is more readily engulfed and destroyed.

Additionally, antibodies can neutralize pathogens by blocking their ability to infect host cells, thereby preventing the spread of infection. This interaction enhances the overall efficiency of the immune response in clearing infections. The other outcomes listed do not reflect the primary purpose or function of antibody-antigen binding within the immune system.
