Across
- 5. Rapid mitosis of lymphocytes after activation
- 9. Engulfs pathogens and presents their antigens
- 11. Organ where T-lymphocytes mature
- 12. Immune response against transplanted organs or tissues
- 13. A foreign protein that triggers an immune response
- 14. First exposure to a pathogen, slower immune reaction
- 15. Proteins released by T-killer cells that punch holes in infected cells
- 16. T-cell that destroys virus-infected or cancerous cells
Down
- 1. Long-lived cells for a faster secondary immune response
- 2. IMMUNITY T-cell response that targets infected body cells
- 3. CELL Cell that displays foreign antigens on its surface
- 4. T-cell that releases cytokines to activate B-cells and macrophages
- 6. Drug given to transplant patients to prevent rejection
- 7. T-cell that switches off the immune response after infection is cleared
- 8. Chemicals released by T-helper cells to activate other immune cells
- 10. Process where a macrophage engulfs a pathogen
