3. cytotoxic T cell, recognize antigen presents via MHC I, directly destroys cells they recognize, often viral infections
6. key player in adaptive immunity, smallest type of WBC with large nucleus and small amount of cytoplasm
8. treating a patient with antibodies against a particular pathogen for immediate effect against pathogen
9. recognize antigen presented via MHC I or MHC II, modulates immune response; calms down the immune response after pathogen is destroyed
10. host proteins displaying antigen fragments on the cell surface: MHC I or MHC II, also called antigen presentation
11. substance that can elicit a response from a B or T cell
12. response when antibodies are able to bind to pathogens and mark them for elimination
14. an immunity obtained by inoculation with selected antigens/parts of a microbe, or the entire microbe; developed by Edward Jenner

1. mature in bone marrow, Y shaped antigen made of 2 heavy and 2 light chains
2. stimulate a primary response and a memory response to a pathogen
4. involves a very specific response to a pathogen and is slower to develop than innate immunity
5. small accessible part of an antigen that binds to an antigen receptor
7. cell record information to fight pathogen if it comes back
8. cell actively secretes antibodies
9. mature in thymus, T shaped antigen, include Th, Tc, and Tregs cells
13. helper T cell, recognizes antigen present via MHC II, detects pathogens and activate other immune cells to fight for them
