Immunity

6. release histamine during inflammatory and allergic reaction
11. specialized t cells destroy affected host cells
13. lymphocyte that produces antibodies
15. trigger apoptosis of foreign cells during cell-mediated response
17. class of proteins in the immune system, antibodies
18. glycoproteins that regulate immune response
19. immune system loses tolerance for self and turns against certain molecules of the body
20. region on antibody that binds to antigens
21. short term immunity resulting from introduction of antibodies from another person or animal
24. lymphocytes that respond to a particular antigen on its reintroduction
25. enhance the ability of antibodies and phagocytes to clear microbes and damaged cells from an organism
26. triggers the humoral and cell-mediated responses
27. parts of the antibody that make each cell specific to one antigen
28. block actions of other lymphocytes to keep the immune system from becoming over-active

1. when a pathogen is marked for destruction by phagocytes
2. resistance to disease
3. protein pair that forms part of the main antigen-binding regions of an antibody
4. differentiated B cells that produce a single type of antibody
5. shows how immunological memory allows a rapid response upon a second exposure to an antigen
7. signaling proteins that cause other cells to heighten anti-viral defenses in response to the presence of a virus
8. immunity resulting from production of antibodies in the presence of an antigen
9. antibodies neutralize or eliminate toxins and pathogens in the blood and lymph
10. protein pair that makes up the major part of an antibody
12. where antibody attaches to antigen
14. substance produced by lymphocytes that acts upon other immune system cells
15. determine the particular class that an antibody belongs to
16. proteins displayed on cell surface responsibe for tissue/organ rejection
22. mature in thymus
23. substance that elicits lymphocyte response
