  1. 4. cells- actively secrete antibodies
  2. 5. Jenner- thought to use cowpox to prevent smallpox
  3. 7. immunity- person is given antibodies rather than producing them
  4. 9. molecules- host proteins displaying antigen fragments on the cell surface
  5. 11. T cells- recognize antigen presented via MHC 1 & express CD8
  6. 12. 1st recorded attempt at immunization occurred in sixth century China
  7. 13. cells- record information to fight pathogen if it comes back
  8. 14. bind only to antigen fragments presented on another cell in MHC context
Down
  1. 1. substances that can elicit a response from B or T cell
  2. 2. T cells- recognize antigen presented via MHC 2 & express CD4
  3. 3. immunization- treating patient with antibodies against pathogen for immediate effect
  4. 6. immunity- specific response to pathogen, slower to develop than innate immunity
  5. 8. stimulate a primary response & a memory response to a pathogen
  6. 10. immunity- exposure to a pathogen triggers antibody production
  7. 15. T cells- recognize antigens presented via MHC 2 & MHC 1
