Across
- 3. host proteins displaying antigen fragments on the cell surface
- 5. have antibody receptors (BCRS)
- 9. thought to use cowpox to prevent smallpox
- 10. recognition of traits specific to particular pathogens, using a vast array of receptors
- 12. have T cell receptors (TCRs)
- 13. treating a patient with antibodies against a particular pathogen for immediate effect against pathogen
- 14. recognize antigen presented via MHC I and express CD8, directly destroy cells they recognize, which are often virus-infected cells
Down
- 1. recognize antigen presented via MHC II or MHC I and express CD4 or CD8, modulate the immune response, including by limiting chronic inflammatory diseases
- 2. actively secrete antibodies
- 3. "record" information to fight pathogens if it comes back
- 4. recognition of traits shared by broad ranges of pathogens, using a smaller set of receptors
- 6. key players in adaptive (acquired) immunity
- 7. substances that elicit a response from a B or T cell
- 8. is any immunity obtained by inoculation with selected antigens/parts of a microbe, or in some cases, the entire microbe
- 11. antibodies defend against infection in body fluids
