Key Features of Adaptive Immunity

  • Specificity: Each immune response targets one specific antigen
  • Memory: Faster, stronger response upon re-exposure
  • Self-recognition: Distinguishes between self and foreign molecules
  • Diversity: Can recognize millions of different antigens
  • Two main types: Humoral (antibody) and cell-mediated immunity

What is an antibody?
A Y-shaped protein (immunoglobulin) produced by plasma cells that binds specifically to antigens to neutralize or mark them for destruction.
What is an antigen?
A foreign substance that triggers an immune response by being recognized as non-self by the immune system.
