Ways Antibodies defend

  1. Opsonization
    Using antibodies to attach microbes to phagocytes or phagocytes to cells recognized as nonself.
  2. MAC Cytolysis
    Using antibodies to activate the classical complement pathway resulting in the lysis of gram-negative bacteria and cells recognized as nonself by way of the membrane attack complex (MAC
  3. Antibody-dependent Cellular Cytotoxicity (ADCC) by NK Cells
    Using antibodies to attach NK cells to infected cells and tumor cells.
  4. Neutralization of Exotoxins
    Using antibodies to prevent exotoxins from binding to receptors on host cells.
  5. . Neutralization of Viruses
    Using antibodies to prevent viruses from binding to receptors on host.
  6. Preventing Bacterial Adherence to Host Cells
    Using antibodies to prevent bacteria from binding to receptors on host.
  7. Agglutination of Microorganisms
    Using antibodies to clump microbes together for more effective phagocytosis.
  8. Immobilization of Bacteria and Protozoans
    Using antibodies to against cilia and flagella to block motility.
