Across
- 2. Cell with long arms, excellent at capturing antigens to activate adaptive immunity.
- 5. Group of about 30 blood proteins that cause the lysis of invading cells.
- 7. Immune receptor that binds to common pathogen structures.
- 8. The process of engulfing and destroying foreign substances.
- 10. Protein molecule, released by macrophages, that modulates the immune response.
- 11. The "first responder" phagocyte with a multi-lobed nucleus.
- 13. Lymphocyte that kills virus-infected and cancerous cells lacking MHC I.
- 14. A phagocytic cell that circulates in the hemolymph of an insect.
Down
- 1. Chemical released by mast cells to dilate blood vessels during inflammation.
- 3. A large phagocytic cell that "eats" pathogens and presents antigens.
- 4. Molecular structure found on pathogens that triggers an immune response.
- 6. Enzyme in tears and saliva that breaks down bacterial cell walls.
- 9. A major type of PRR that binds to pathogen fragments like LPS or flagella.
- 12. Protein released to "interfere" with viral replication in nearby cells.
- 15. Granulocyte that discharges enzymes to destroy parasitic worms.
