- 4. The process of consuming and digesting cells and invaders
- 6. Third line of defense that helps protect vertebrates from almost any invader
- 7. Hormone-like messenger that facilitate communication between the cells of the immune system
- 8. Type of binding that occurs after a helper T cell binds to a class II MHC molecule displaying a cognate antigen
- 9. A sentinel that mostly is in a dormant state that lives in endothelial cells and recruits the rest of the innate immune system upon an infiltration
- 10. Protein that is only found in the "hands" region of IgG antibody (two words)
- 15. Makes it its business to eat invaders (2 words)
- 17. The display of these proteins are only intended for the enlightenment of helper T cells; alerts of a problem outside of cells (three words, last one abbreviated)
- 18. the process of only replicating B cells when their cognate antigen is found as to not waste space and resources to fight against invaders not currently in the body (two words)
- 20. Antibody-like-molecule on the surface of T cells that is made by modular design strategy
- 21. Digestive vesicle of cells that contains enzymes that could kill the host cell if released
- 23. Destroys virus-infected cells by making contact with the cell and "assisting its suicide" (three words)
- 26. Found on most cells surfaces of the body, informs T cells about what is going on inside the cell (three words, last one abbreviated)
- 30. The disease that was collected from pus so Edward Jenner could inoculate James Phipps
- 32. A protein that "presents" information for T cells to "view" about cells (three words)
- 34. The type of cells that line the inside of capillaries
- 36. The disease Edward Jenner vaccinated the English from in the 1790s
- 37. The agent that causes an antibody to be made
- 38. Second line of defense after the first line is breached (three words)
Down
- 1. Directs action through secreting cytokines that have dramatic effects on other immune system cells (three words)
- 2. Also known as the secondary lymphoid organ, this organ acts as a station to drop off the cargo that is invaders for B and T cells to attack and get rid of (two words).
- 3. Helps keep the immune system from overreacting (three words)
- 4. White blood cells that are born in the bone marrow and can mature to become antibody factories
- 5. "Test batch" of antibodies (three words)
- 11. Protein that is found in both the "hands" and "tail" regions of IgG antibody (two words)
- 12. First line of defense against invaders (two words)
- 13. Name of structure where an IgG binds to a cell surface (two words)
- 14. Stops a virus from entering/reproducing within a cell
- 16. The "tail" of an IgG antibody that can bind to receptors on cell surfaces (two words)
- 19. Utilizes "one for me, one for you" process while replicating (2 words)
- 22. what antibodies do to an invader, "to prepare for eating"
- 24. "Leftover" B and T cells from an attack that are more numerous than inexperienced B and T cells and are easier to activate to help defend from following attacks.
- 25. Immature macrophage cell that just left the bone marrow and entered the blood
- 27. Prototype antibody (two words)
- 28. Special proteins that circulate the blood of immunized individuals
- 29. The "hand" of an IgG antibody (two words)
- 31. Vesicle that a bacterium is engulfed in when a macrophage discovers it
- 33. The molecule that fits the Fab region of a B cell receptor (two words)
- 35. The only cells that can make class II MHC molecules
