Across
- 8. Inflammatory chemicals attract neutrophils to the injury site.
- 10. Response is mostly IgG.
- 13. The actual part of an antigen that interacts with the immune cell to stimulate the immune response and antibody production.
- 18. Secreted early in the immune response.
- 19. What is LFA-1?
- 21. Cells that have not yet encountered their specific antigens.
- 24. Proteins produce by the immune system in response to the presence of a foreign substance.
- 25. Term given when 2 cytokines combine and give greater effects.
- 28. Cells involved in killing of antibody-coated parasites.
- 30. Proteins are sequentially activated in a cascade.
Down
- 1. A specific type of antigen that is able to induce adaptive immune response if injected on its own.
- 2. Antiviral Defense
- 3. Binding of peptide by MHC molecule and displaying the complex on the cell surface.
- 4. It is a substance of low molecular weight, which can react with specific antibody without inducing immune response.
- 5. Neutrophils squeeze through capillary walls and begin phagocytosis.
- 6. Mediated by antibodies, which are produced by cells called B lymphocytes.
- 7. A molecule is expressed IgM and IgD on its surface.
- 9. Degradation of proteins into peptides.
- 11. It is an automatic response to cell injury that eliminates harmful agents & removes dead tissues.
- 12. Proteins produced by pathogens but not processed by antigen presenting cells.
- 14. Antibody crosses the placenta.
- 15. Is the coordinated reaction of these cells and molecules to infectious microbes.
- 16. A chemical substance that encourages a cell to commence cell division by mitosis.
- 17. Mediated by cells called T lymphocytes.
- 20. Nneutrophils are released from the bone marrow in response to leukocytosis-inducing factors released by injured cells.
- 22. Cells involved in phagocytosis and activation of bactericidal mechanisms.
- 23. Is where phagocytic cells surround and ingest foreign materials.
- 26. Binding of C3b to microbe
- 27. A molecule is to induce the movement of leukocytes up a concentration gradient and toward the chemokine source.
- 29. The region at which arms of the antibody (ab) molecule forms a Y.
