Complement Activation

Complement activation is a part of the immune system that helps the body fight infections. When the body detects a threat like bacteria or viruses, a series of proteins called "complement proteins" are triggered. These proteins work together, leading to processes like marking invaders for destruction, attracting immune cells to the site of infection, and directly damaging the invaders' outer structures. This activation enhances the body's ability to clear infections efficiently. It’s a crucial, rapid response mechanism that supports immune defense beyond just antibody action.
