innate immunity Flashcards
which type of immunity has a lag period?
adaptive immunity
what does innate immunity target?
microbes (molecular patterns)
what does adaptive immunity target?
antigens
does innate immunity have memory?
nope. it just looks for general patterns
- you get the same response every time
does adaptive immunity have memory?
yep. it looks for specific epitopes.
- the response gets better with time
what type of immunity is self-tolerant?
both!
what do toll-like receptors do?
-recognize double stranded RNA (which is weird so cool)
what are the two main structures that provide mechanical factors?
skin and mucous membranes
of neutrophils, monocytes, and macrophages, which ones are innate immune system and which are innate and adaptive?
- Neutrophils are innate only
- macrophages and monocytes are both innate and adaptve
what are the functions of neutrophils?
- phagocytosis and intracellular killing
- inflammation and debridement
what are the functions of macrophages?
- phagocytosis and intracellular killing
- antigen presentation for specific immune response
what are the functions of eosinophils?
- killing of certain parasites and involved allergies
- activate cells that increase histidine production
what lymphocytes are most abundant?
neutrophils and then lymphocytes
what lymphocyte arrives first at the site of infection/injury?
neutrophils
what do neutrophils do after they eat the cell?
they kill themselves.
