chapter 13

2. response when the antibodies are able to bind to pathogens and mark them for elimination
4. cells that directly destroy cells they recognise
6. the tips of the chain form what region
7. cells that modulate the immune system
9. treating a patient with antibodies against a particular pathogen for immediate effect against pathogen.
10. substances that can elicit a response from a B or T cell
12. have antibody receptors
13. immunity that develops when the innate immune system cannot handle getting rid of the pathogen.
14. cells that actively secrete antibodies
16. cells induced to fight the infection if it comes back

1. used to stimulate a primary response and a memory response to a pathogen
3. immunity from exposure to a pathogen that triggers antibody prouction
5. T cells that recognize antigen presented via MHC II and also express CD4
8. Binding of a BCR to an antigen is an early step in B cell activation, as before this B cells are termed
11. the receptors on a single B cell or T cell are all what to one another
15. the key players of adaptive (acquired) immunity
