Across
- 4. Type of defence that reacts immediately.
- 7. Immune response using T cells.
- 10. An activated T cell presents an x.
- 11. These cells from B cell differentiation are more like B cells.
- 12. These cells churn out antibodies.
- 14. Type of cells that respond to chemicals released by pathogens during infections.
- 15. Memory cells are not active, they are x.
Down
- 1. Antibodies are also called x.
- 2. B cells divide and this causes x so that resulting cells are either plasma or memory B cells.
- 3. These are attenuated viruses.
- 5. Binding of antigen can inactivate the x by lysis or phagocytosis.
- 6. An x binds to an antigen.
- 7. x T cells (killer T cells).
- 8. White blood cells.
- 9. Antibodies that are artificially produced.
- 10. Binding of this with the T helper cell stimulates a reaction.
- 13. Antibody-mediated immune response.
