Special protein that atacches to a specific pathogen?

The special protein that attaches to a specific pathogen is called an antibody. Antibodies are produced by the immune system in response to antigens, which are unique molecules found on the surface of pathogens like bacteria and viruses. By binding to these antigens, antibodies help neutralize the pathogen and mark it for destruction by other immune cells. This specificity enables the immune system to effectively target and eliminate a wide variety of infectious agents.
