Antibody Complexes

Antibody complexes form when antibodies, which are proteins produced by the immune system to identify and neutralize foreign invaders like bacteria and viruses, attach to specific antigens on these invaders' surfaces. This binding creates an antibody-antigen complex that marks the invader for destruction by other immune cells or neutralizes it directly. These complexes are essential for immune defense, helping the body target and eliminate threats effectively. They also play a role in immune regulation and can be involved in immune-related conditions if they form inappropriately or excessively.
