R( ^& G0 t" P9 q2 RA macrophage attacking bacteria. Macrophages are phagocytic cells found in blood, lymph and in all mammalian tissue types. They have many and diverse roles in normal development, homeostasis, tissue repair and the immune response to pathogens. Their diversity means that they are involved in almost every human disease and are prime therapeutic targets because their function can be augmented or inhibited to alter disease outcome. A Review in this issue discusses macrophage physiology in terms of the homeostatic mechanisms by which macrophages contribute to physiological and pathophysiologic adaptations in mammals.
