  • Antibodies and Antigens
    • Antigens
      • Glycoproteins protruding from the surface of the cell
      • Stimulate the production of antibodies
      • Recognised by WBCs in specific response to infection
      • Can be toxins produced by pathogens
      • Only identical twins have same antigens
    • Antibodies
      • Proteins that binds to antigents on certain pathogens destroying them
      • Plasma cells secrete antibodies
      • Cause pathogens to agglutinate/clump together stopping spread
      • Antibody-antigen complex makes it easier for phagocytes to digest them
        • Complex can stimulaterelease of histamine to cause inflammation
