Neutrophils, the predominant phagocytes of circulating blood, are the first cells to arrive at sites of infection. Although neutropenia has long been recognized to predispose to infection, recently other syndromes marked by frequent infections have been shown to be caused by an underlying neutrophil dysfunction. Efforts to define the molecular pathology of such disorders have helped delineate the molecular basis of normal neutrophil function. Advances have been made in defining the roles of the neutrophil's varied receptors in recognition, movement, and adhesive phenomena. Progress in establishing the pathogenesis of chronic granulomatous disease has provided important insights into the enzymatic machinery that normal neutrophils use to produce antimicrobial oxidants. The identification and precise characterization of antimicrobial components, such as defensins, have outlined the potential roles of "natural antibiotics" in neutrophil-mediated host-defense functions. These areas of neutrophil function will be reviewed and placed in a clinical context to guide physicians in evaluating children and adults with frequent or unusual infections.
