Interestingly, do not directly attack, nor destroy, any pathogens. They to pathogens, and in doing so render them incapable of causing an immune response. This opens binding sites and promotes , resulting in a conversion of complement proteins to fight the pathogen. Antibodies that bind to more than one cell simultaneously can rapidly cause to occur, which is a clumping that prevents the pathogen from contacting and damaging human cells. This process makes the molecule insoluble and less mobile. This is an example of .
