Across
- 2. Cells that make class II MHC molecules (abbreviation)
- 6. T cell that destroys virus infected cells
- 8. Sentinel cells that can found just below the surface of tissues exposed to the environment
- 9. Process by which antibodies bind to bacteria and viruses and tag them for destruction
- 10. Protein that neutrophils rapidly mobilize to the surface to stop at the site of infection
- 12. Vesicle that contains an invader digested by a phagocyte
- 15. Method by which the 4 gene modules(V,D,J,C) are combined to make an antibody
- 16. Hormone-like messengers which facilitate communication between cells of the immune system
- 17. Molecule on the surface of gram negative bacteria (abbreviation)
- 19. Process where a B cell is triggered to double in size and divide into two daughter cells
- 20. T cell that secretes cytokines to "direct the action" of the immune response
- 21. A Y shaped protein that is made in response to exposure to a particular antigen and secreted into the blood
Down
- 1. Chemicals that can recruit other immune system cells to the battle site, such as C3a and C5a
- 3. Cells most associated with type I interferon production (abbreviation)
- 4. Organ in the body primarily responsible for producing complement proteins
- 5. Antibodies that bind to viruses so that viruses cannot enter your cells
- 7. T cell that helps restrain the immune system so it doesn't overreact
- 11. Short-lived cell that circulates in the blood and is "on call" to leave the blood to kill invaders
- 13. An antibody that has been anchored on the surface of a B cell
- 14. Region of an antibody that can bind to antigens
- 18. Region of an antibody that binds to receptors on the surface of cells
