Across
  1. 4. Any substance that triggers an immune response from B or T cells.
  2. 5. A type of white blood cell (B cells and T cells) that play a major role in adaptive immunity.
  3. 7. The process of displaying antigen fragments on MHC molecules so T cells can recognize them.
  4. 8. A receptor on B cells that binds directly to antigens and helps activate the B cell.
  5. 10. A protein produced by B cells that binds to pathogens to mark them for destruction.
  6. 11. The part of immunity involving B cells and antibodies circulating in body fluids.
  7. 15. T cells that activate and coordinate other immune cells to respond to infection.
Down
  1. 1. A specific, slower immune response that targets particular pathogens and creates memory for future protection.
  2. 2. The process of exposing the body to antigens to stimulate immunity and create memory without causing disease.
  3. 3. Proteins on cell surfaces that present antigen fragments to T cells.
  4. 6. A receptor on T cells that recognizes antigen fragments presented by other cells.
  5. 9. T cells that directly kill infected or abnormal (like cancer) cells.
  6. 12. Activated B cells that produce and secrete large amounts of antibodies.
  7. 13. The specific part of an antigen that an immune cell receptor binds to.
  8. 14. Long-lived B or T cells that “remember” a pathogen and respond faster if it returns.
