emigration of neutrophils into tissues
phagocytes are elements of innate immune system what are the two types?
macrophages (arrive first)
neutrophils (which are called my macrophages)
_____ are the guardians of innate immunity
macrophages
what are the phagocytes in innate immunity?
macrophages and neutrophils
macrophages can recognize _____ which is present with tissue damage
DAMPs
what kind of receptors do macrophages use to recognize PAMPs?
toll-like receptors
what are inflammasomes used for?
recognizing cell damage to then produce IL-1 which triggers release of other inflammatory mediators
neutrophils are derived from ____ then circulate in the blood stream
