Notes de l'éditeur

  1. Self recognition is important in an immune response Presence of receptors/markers in pathogens that enter the body Very efficient, even undigested proteins are considered as antigens
  2. Single lymphocyte has ~100,000 receptors for antigen Differentiation of unspecialized lymphocytes gives rise to diversity of the antibody or receptor Makes it possible to respond to different pathogens
  3. Re-exposure- response is faster, greater magnitude and more prolonged
