Immune Response Crossword

3. Barriers that are used to prevent pathogens from entering the body.
5. A type of acquired immunity that uses T-cells to respond to body cells that have already been infected by a foreign pathogen.
6. A slow immune response that attacks a specific pathogen using humoral and cell-mediated immunity.
9. Substances (molecules) that are produced by the immune system to trigger a specific immune response.
10. Immune cells that “eat” pathogens and then die creating “pus”.
14. A quick immune response using your skin and mucous membranes that is general (nonspecific).
16. A specific type of lymphocyte that responds to antigens before a foreign pathogen infects body cells.
17. Immune cells that “eat” pathogens using cytoplasmic extensions (arms).
18. Type of immunity that is “borrowed” and occurs when we are injected with antibodies from the blood serum of an individual that has already been infected.
19. Immune cells that join Mast cells in stimulating blood vessels to dilate/constrict.
20. Warning signal proteins secreted by virally-infected body cells.
23. Immune cells that lyse (explode) infected or abnormal body cells based on a lack of “self” surface receptors (MHC-II).
24. Type of T-cell used to react to a second infection from the same pathogen more quickly.

1. Type of immunity that is “borrowed” and occurs when antibodies are passed from a mother to child through breastmilk or the placenta.
2. Barriers that are activated once a pathogen has entered the body.
4. Type of T-cell that recognizes antigen presenting B-cells causing a signaling cascade
5. Chemical signals used to help cells communicate during an immune response.
6. Substances (molecules) that are produced by lymphocytes to match and detect specific antigens.
7. Type of immunity that is “earned” and occurs when we contract an infection.
8. Type of T-cell that binds to infected body cells and causes apoptosis.
9. Type of immunity that is “earned” and occurs when we are given a vaccine.
11. Immune cells that respond to body cells that have already been infected with a foreign pathogen.
12. Proteins that work with other defenses by lysing pathogenic bacteria or marking pathogens for easier phagocytosis.
13. Immune cells that are responsible for responding to the release of antigens.
15. Long lived B-cells that produce a swift and strong response if the same antigen is encountered in the future. (“secondary response”)
21. Type of T-cell that releases chemicals to slow the immune response after the antigen is destroyed.
22. A type of acquired immunity that uses B-cells to respond to antigens before cells are infected by a foreign pathogen.
