Immune system NB
Across
- 3. These cells have receptors that react directly with antigens in the blood.
- 4. These antibodies are produced to target only one specific epitope.
- 6. Vaccines contain these types of pathogens, which are modified to trigger an immune response
- 7. What term refers to foreign molecules that stimulate an immune response?
- 8. Lymphocytes that mature in this organ become T cells.
- 12. This type of MHC protein is displayed on macrophages after they engulf a pathogen
- 14. This process involves blocking viral binding sites and coating bacterial toxins
- 15. This antibody class protects mucosal surfaces and is secreted in saliva and tears.
- 16. These cells, including eosinophils and neutrophils, move out of capillaries into tissues during infection
Down
- 1. These cells arise from activated B cells and produce antibodies.
- 2. Memory cells are in this phase of the cell cycle when they are not actively dividing.
- 5. These cells are activated by infected cells and are responsible for killing those infected cells
- 7. This Y-shaped protein binds to specific antigens to help neutralize pathogens.
- 9. These proteins released by Cytotoxic T cells create pores in the membrane of infected cells.
- 10. These cells persist in the body and are similar to the original B cells, ready for future encounters with the same antigen.
- 11. Interleukin-2 is an example of this type of signaling molecule.
- 13. This term describes the antibody-mediated immune response.
