Across
- 2. Immunization The administration of antibodies against a particular pathogen to provide immediate but temporary protection without inducing immune memory.
- 3. Receptor A receptor consisting of two different polypeptide chains, alpha and beta, whose variable regions form an antigen-binding site.
- 5. A specific immune response that develops when innate immunity cannot eliminate a pathogen and produces memory cells to fight future infections.
- 6. T lymphocytes that recognize antigens presented by MHC II, express CD4, and activate other immune cells to fight pathogens.
- 8. White blood cells that are the key players in adaptive immunity, with dark, round nuclei and little cytoplasm.
- 10. A Y-shaped protein molecule consisting of two identical heavy chains and two identical light chains that recognizes specific antigens.
- 12. Cells that record information about a pathogen and help fight the infection if it returns.
- 13. T lymphocytes that modulate the immune response, including limiting chronic inflammatory diseases.
- 14. Substances that can elicit an immune response from B cells or T cells.
- 15. Soluble proteins produced by plasma cells that bind to pathogens and mark them for elimination.
Down
- 1. The process of obtaining immunity through inoculation with selected antigens, parts of a microbe, or sometimes an entire microbe.
- 4. T lymphocytes that recognize antigens presented by MHC I, express CD8, and directly destroy infected cells.
- 7. The small accessible part of an antigen that binds to an antigen receptor.
- 9. An adaptive immune response in which antibodies defend against pathogens in body fluids.
- 11. Cells Activated B cells that actively secrete antibodies.
