WebJan 17, 2024 · Antibodies that bind to surface antigens on a bacterium attract the first component of the complement cascade with their Fc region and initiate activation of the classical complement system. Key Terms epitope: Part of a biomolecule (such as a protein) that is the target of an immune response. The fragment crystallizable region (Fc region) is the tail region of an antibody that interacts with cell surface receptors called Fc receptors and some proteins of the complement system. This property allows antibodies to activate the immune system. In IgG, IgA and IgD antibody isotypes, the Fc region is composed of two identical protein fragments, derived from the second and third constant
