title: Biological activities of human granulocyte-macrophage colony-stimulating factor.
abstract: Granulocyte-macrophage colony-stimulating factor (GM-CSF) has emerged as an important regulation for hematopoietic cell development and function. Within the myeloid lineages, GM-CSF serves as a growth and developmental factor for intermediate-stage progenitors between early, interleukin 3-responsive and late granulocyte colony-stimulating factor-responsive precursors. GM-CSF also serves as an activator of circulating effector cells. The ability of GM-CSF to induce monocyte expression of tumor necrosis factor, interleukin 1 and other factors, further ties this hormone into a network of cytokines that interact to regulate many hematologic and immunologic responses. The availability of large quantities of recombinant GM-CSF now provides the opportunity and challenge not only for unraveling the mechanisms regulating hematopoiesis, but also for developing new therapies for enhancement of host defense against infection that were not previously possible.
