A knowledge of eosinophil granulocytes is indispensable for the study of hypereosinophilia. For this reason, the most recent findings relating to eosinophil morphology, production/regulation mechanism, and function are reported. Particular attention is given to enzyme populations, local control mechanisms and eosinophil cell surface receptors. Among the various enzymes present in the eosinophil, major basic protein (MBP), with its capacity to damage the cells of many organs, plays an important part; other enzymes include eosinophil peroxidase (EPO), arylsulphatase B, phospholipase D, histaminase and cationic proteins (ECP). Factors influencing eosinophil tissue concentrations and mode of action are considered. Recent findings agree on the role of eosinophils in immunological reactions and parasitic infestations: eosinophil plays a part in an immunological physiopathological sequence: it may, act as a killer cell with selective action against invading parasites, or it may be an immune modulator, anti-inflammatory cell able to surround inflammatory reactions and prevent them from spreading.
