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
