The autoimmune response causes the immune system to attack the body's own cells. The hypersensitivity response, mediated by IgE, causes the release of harmful chemical mediators. Recognition of MHC molecules as nonself in a transplanted organ can cause organ rejection. Activation of the complement system causes a cascade of reactions that assist in the immune response. Opsonization is a process that assists with phagocytosis.
