adaptive immunity triggered when
how does adaptive arm of immune response kick in
what characterises resolution of infection
4 steps of innate reaction to pathogen
major cells of innate
neutrohils
surface receptors on neutrophils
opsonisation
surface receptors on monocytes/macrophages
NK cells
surface receptors on NK cells
how are NK cells activated
mast cells + basophils
step one: mo+dc produce/secrete cytokines
step two: effector cells recruited
step 3: neutrophils arrive
basophils + mast cells release granules when stimulated by:
step four: acute phase response activated
dendritic cells
recognition of microbes by innate immune system: receptor list (5)
what are acute phase proteins?
what are cytokines
what are interleukins
interferons
