CH 12

4. (immunity) recognition of traits specific to particular pathogens, using a vast array of receptors, slower response
7. provide innate defense, interfering with viruses and helping activate macrophages
8. natural killer cells, a type of lymphocyte, circulate through the body and detect abnormal cells, like cancer cells
9. Pattern Recognition Receptors, found on innate immune cells
12. recognizes LPS (a Gram(-) cell wall component
13. circulate the blood and are attracted by signals from infected tissues, granulocyte, first responder to an infection
14. circulate within hemolymph and carry out phagocytosis, there is no blood

1. Patttern Associated Molecular Patterns, found on potential pathogens
2. (system) consists of about 30 proteins that are activated by substances on microbe surfaces
3. stimulate development of adaptive immunity in cells that contact the environment (such as skin), agranulocytes, have long arms
5. recognizes viral RNA
6. discharge destructive enzymes, granulocytes, involved in allergic and anti-helminth (worms) responses
10. (immunity) all animals and plants, recognition of traits shared by broad ranges of pathogens, using a small set of receptors, rapid response
11. found throughout the body, agranulocytes, originate from monocytes
12. recognizes bacterial flagella
