Across
  1. 4. : Reduced ability of the immune system to respond effectively
  2. 8. : Engulfing and digesting pathogens by phagocytes
  3. 9. : Programmed cell death that removes infected or damaged cells
  4. 12. : Secretions such as stomach acid lysozyme and saliva
  5. 13. : Molecule that triggers a specific immune response
  6. 14. : Structural defence such as skin or mucous membranes
  7. 15. : Non specific defence mechanisms present from birth
  8. 16. : Identical laboratory made antibodies that target one antigen
  9. 17. : Medical treatment that enhances or suppresses immune function
  10. 20. : Y shaped protein made by B cells that binds to a specific antigen
  11. 21. : White blood cell that differentiates into plasma and memory cells
  12. 22. : Disease causing agent such as a virus bacterium fungus or parasite
  13. 23. : Differentiated B cell that secretes antibodies
  14. 24. : Non specific reaction with swelling redness and heat
  15. 25. : Community protection when most people are immune
  16. 26. : Protein on cell surfaces that distinguishes self from non self
  17. 27. : Signalling protein that coordinates immune cell communication
  18. 29. : Overreaction of the immune system to a harmless antigen
  19. 31. : Activation of specific lymphocytes after binding to antigen
Down
  1. 1. : Slower first response by naive lymphocytes
  2. 2. : Administration of a vaccine to stimulate immunity
  3. 3. : Rapid replication of the selected lymphocytes
  4. 5. : Specific acquired immune response that forms memory cells
  5. 6. : T cell that activates B and cytotoxic T cells by releasing cytokines
  6. 7. : Condition where the immune system attacks self antigens
  7. 10. : Faster stronger response due to memory cells
  8. 11. : Preparation containing antigen that induces artificial active immunity
  9. 18. : Cell that displays antigen fragments to activate T cells
  10. 19. : T cell that kills infected or abnormal cells
  11. 28. : White blood cell responsible for cell mediated immunity
  12. 30. : Long lived lymphocyte that provides a faster secondary response
