An overview of findings on the biology of neutrophils. These cells have become a focus of attention because of their fascinating biochemistry and molecular biology and their ability to affect the functions of other cells. The book describes, in detail, the molecular events leading to neutrophil activation, migration, microbial killing, production of oxidative radicals and cytokines, and eventually to the death of these cells. It also provides an overview of the neutrophil's role in viral diseases, including AIDS. Finally, the book describes how to improve the function of neutrophils and use these cells in the treatment of diseases.
