Across
  1. 3. Does acquired immunity display a SLOWER or FASTER response to specific microbes?
  2. 5. Diseases in which the immune system loses tolerance for self & turns against certain molecules of the body
  3. 8. What does an acute allergic response sometimes lead to?
  4. 9. infects helper T cells
  5. 12. Active chemicals which is stored in mast cells
  6. 14. Long lived cells bearing receptors specific for the same inducing antigen
  7. 16. A type of white blood cell that mediates acquired immunity
  8. 17. a vertebrate body cell that produces histamine and other molecules that trigger the inflammatory response
  9. 18. occurs when a pathogen can no longer infect a host because it is bound to an antibody
  10. 19. An enzyme that digests the cell walls of many bacteria
Down
  1. 1. Cells derived from B lymphocytes secrete defensive proteins called antibodies
  2. 2. short-lived cells that combat the same antigen
  3. 4. secreted antibodies which are structurally similar to B cell receptors but lack transmembrane regions
  4. 6. antigen-driven cloning of lymphocytes
  5. 7. can bind to an antigen that is free or on the surface of a pathogen
  6. 10. this type of immunity is present before any exposure to pathogens & is effective from the time of birth
  7. 11. Small proteins that direct the migration of phagocytes & signal them to increase production of microbe killing compounds
  8. 13. Which type of response serves as an internal defense
  9. 15. A surface protein is present on most cytotoxic T cells, greatly enhances the interaction between a target cell & cytotoxic T cell
  10. 19. What is it called when some viruses remain in a host cell in an inactive state
