An increasing number of cytokines including GM-CSF, G-SCF, M-CSF, IL-3, IL-1 and IL-4, have been implicated in the control of the growth and differentiation of hematopoietic cells. The characterization of the cell surface receptors for these proteins is described. The binding of rh IL-3 to human monocytes is described in some detail, and the binding parameters measured for this cytokine are compared with those determined for the other cytokines. The range of cells to which rh IL-3, rh GM-CSF and rh G-CSF bind is more restricted than that observed for the cytokines IL-1 and IL-4, which bind to a diverse spectrum of cell types. Practical applications of receptor studies include the determination of receptor affinity as a measure of recombinant cytokine potency and the use of the receptor ligand interaction to establish sensitive radioreceptor assays for the detection of cytokines in solution. Finally, methods used for the molecular characterization of cytokine receptors are described and summarized for the CSF receptors, IL-4 and IL-1.

UI	MeSH Term	Description	Entries
D007375	Interleukin-1	A soluble factor produced by MONOCYTES; MACROPHAGES, and other cells which activates T-lymphocytes and potentiates their response to mitogens or antigens. Interleukin-1 is a general term refers to either of the two distinct proteins, INTERLEUKIN-1ALPHA and INTERLEUKIN-1BETA. The biological effects of IL-1 include the ability to replace macrophage requirements for T-cell activation.

D007377	Interleukin-3	A multilineage cell growth factor secreted by LYMPHOCYTES; EPITHELIAL CELLS; and ASTROCYTES which stimulates clonal proliferation and differentiation of various types of blood and tissue cells.

D007378	Interleukins	Soluble factors which stimulate growth-related activities of leukocytes as well as other cell types. They enhance cell proliferation and differentiation, DNA synthesis, secretion of other biologically active molecules and responses to immune and inflammatory stimuli.	Interleukin
D007700	Kinetics	The rate dynamics in chemical or physical systems.
D011956	Receptors, Cell Surface	Cell surface proteins that bind signalling molecules external to the cell with high affinity and convert this extracellular event into one or more intracellular signals that alter the behavior of the target cell (From Alberts, Molecular Biology of the Cell, 2nd ed, pp693-5). Cell surface receptors, unlike enzymes, do not chemically alter their ligands.

D011971	Receptors, Immunologic	Cell surface molecules on cells of the immune system that specifically bind surface molecules or messenger molecules and trigger changes in the behavior of cells. Although these receptors were first identified in the immune system, many have important functions elsewhere.
