Across
- 6. Substances that can elicit a response from B or T cell. cell.
- 7. "Record" information to fight pathogen if it comes back.
- 10. Recognize antigen presented via MHC 1 and express CD8. Directly destroy cells they recognize, which are often virus-infected cells.
- 11. Develops when the innate immune system cannot handle getting rid of a pathogen.
- 12. Key players of the adaptive (acquired) immunity.
- 14. The small accessible part of an antigen that binds to an antigen receptor.
- 15. Host proteins displaying antigen fragments on the cell surface.
- 16. A subset against primarily intracellular pathogens.
Down
- 1. Exposure to a pathogen triggers antibody production.
- 2. Actively secrete antibodies.
- 3. The antibodies (rather than B-cells) defend against pathogens. The antibodies bind to pathogens and mark them for elimination.
- 4. A person is given antibodies rather than producing them.
- 5. Deliberate inoculation of dried pus from smallpox pustules of one patient into the arm of a healthy person.
- 8. Recognize antigen presented via MHC 2 or MHC 1 and express CD4 or CD8. Modulate the immune response, including by limiting chronic inflammatory diseases.
- 9. A subset that contribute to protection at mucosal surfaces.
- 13. A subset leading to a humoral response.
