MeSH ID D009504

Neutrophils are the major bacteria-killers in the blood, they kill bacteria via two major mechanisms: the production of free radicals like hydrogen peroxide and bleach and (after phagocytosis) defensin (an antimicrobial protein)-mediated destruction (via 'poking holes' into the phagocyted invader) of the invader. They comprise some 50-70% of the leukocytes found in the blood. They are classed as granulocytes.[1] They form part of the innate immune response.
