Across
- 2. A B cell that produces antibodies after meeting its matching antigen.
- 5. A type of T cell that destroys infected or abnormal cells in the body.
- 6. Type of immunity where the body is given antibodies made by another person.
- 9. A type of cancer cell used in monoclonal antibody production because it divides continuously.
- 14. A cell made by fusing a plasma cell and a cancer cell to make antibodies in large amounts.
- 16. A chemical released during infection to attract neutrophils to the damaged tissue.
- 18. The process where white blood cells engulf and digest pathogens.
- 19. The first immune response after a pathogen enters the body.
- 20. The faster, stronger immune response when the same pathogen enters again.
Down
- 1. Type of immunity a person gets without medical help, like from infection or from antibodies passed by the mother.
- 3. Type of immunity where the body makes its own antibodies after contact with an antigen.
- 4. A short-lived phagocyte that quickly responds to infection and forms pus when it dies.
- 7. Type of immunity given by medical treatment, such as vaccines or antitoxin injections.
- 8. A word to describe identical (only one type of) antibodies made from one type of plasma cell.
- 10. Long-lived phagocytes that cut up pathogens and present antigens to lymphocytes.
- 11. A chemical messenger released by T helper cells to help activate other white blood cells.
- 12. A safe/weaken version of a pathogen (containing antigen) given to cause an immune response and create memory cells.
- 13. A protein made by plasma cells that attaches to antigens.
- 15. A type of T cell that helps start the immune response by releasing cytokines.
- 17. This type of cell remains in the body after infection and helps in a faster response if the same antigen returns.
