Interleukin 11 (IL-11) is a multifunctional cytokine which may play a role in regulating the growth and development of cells in both the hematopoietic and lymphoid systems. IL-11 activity was originally detected in the conditioned medium of a primate bone marrow stromal cell line, and the human cDNA was cloned from a human fetal lung fibroblast cell line. The purified protein shows multifunctional activity, influencing lymphohematopoietic stem cell proliferation and differentiation, megakaryocyte progenitor cell proliferation and differentiation, erythroid progenitor cell proliferation, B lymphocyte maturation, activation of hepatocyte acute phase protein synthesis, and adipogenesis. At the molecular level, IL-11 is unique, containing no asparagine-linked glycosylation sites and no cysteine residues. The IL-11 receptor belongs to a family of cytokine receptors which includes the receptors for IL-6, leukemia inhibitory factor (LIF), oncostatin M (OSM), and ciliary neurotrophic factor (CNTF), which are all capable of interacting with the signal transducing receptor gp130 after ligand binding. IL-11 has demonstrated activity in preclinical models for the treatment of thrombocytopenia and, in some cases, neutropenia; studies are underway to confirm its usefulness in the clinic for treatment of myelosuppression associated with cancer chemotherapy and bone marrow transplantation.

Granulocyte colony-stimulating factor (GCSF) is the principal growth factor regulating the maturation, proliferation and differentiation of the precursor cells of neutrophilic granulocytes and is used to treat neutropenia. GCSF is a member of the long-chain subtype of the class 1 cytokine superfamily, which includes growth hormone, erythropoietin, interleukin 6 and oncostatin M. Here we have determined the crystal structure of GCSF complexed to the BN-BC domains, the principal ligand-binding region of the GCSF receptor (GCSFR). The two receptor domains form a complex in a 2:2 ratio with the ligand, with a non-crystallographic pseudo-twofold axis through primarily the interdomain region and secondarily the BC domain. This structural view of a gp130-type receptor-ligand complex presents a new molecular basis for cytokine-receptor recognition.
