Eosinophil is a cell . WBC Polymorphonuclear Leukocytes
Eosinophils are important in phagocytosis as well as in allergic and inflammatory reactions. can kill helminths by ADCC .
A polymorphonuclear leukocyte with large eosinophilic (i.e. red) cytoplasmic granules.
Eosinophil function is incompletely understood. They are prominent at sites of allergic reactions, and with parasitic ( helminths ) infections. Eosinophil secretory products inactivate many of the chemical mediators of inflammation. This phenomenon is most obvious with mast cell-derived mediators. Mast cells produce a chemotactic factor for eosinophils. Secretory products of eosinophils:
major basic protein (MBP) the substance that can kill parasitic larvae (helminths), inactivates heparine .
