A polymorphonuclear leukocyte with large eosinophilic (i.e. red) cytoplasmic granules.
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 .
