The cytokines that signal through the common receptor subunit gp130, including ciliary neurotrophic factor (CNTF), interleukin-6, leukemia inhibitory factor (LIF) and oncostatin M, have pleiotropic functions in CNS development. Given the restricted expression domain of the CNTF receptor alpha (CNTFR) in the developing forebrain germinal zone and adult forebrain periventricular area, we have exa...

Macroscopic carbon nanotube fiber (CNTF) is a continuous monofilament microns-thick thread whose cross section consists of ten to hundreds millions tightly packed, aligned nanotubes (CNTs). CNTF flexible, strong, conductive, and has excellent electrochemical properties, making it an ideal candidate for bioelectronic interfaces. recent applications range from neuroelectronics cardiac electrophys...

Axonal maintenance, plasticity, and regeneration are influenced by signals from neighboring cells, in particular Schwann cells of the peripheral nervous system. Schwann cells produce neurotrophic factors, but the mechanisms by which ciliary neurotrophic factor (CNTF) and other neurotrophic molecules modify the axonal cytoskeleton are not well understood. In this paper, we show that activated si...

Ciliary neurotrophic factor (CNTF) and basic fibroblast growth factor (bFGF) were tested for effects on sprouting by motor neurons innervating the adult mouse gluteus muscle. Factors were delivered by subcutaneous injection directly over the surface of the superior gluteus muscle once daily for 7 d and then end plates and axons were visualized by combined silver and cholinesterase staining. CNT...

Obesity and its related cluster of pathophysiologic conditions including insulin resistance, glucose intolerance, dyslipidemia, and hypertension are recognized as growing threats to world health. It is now estimated that 10% of the world's population is overweight or obese. As a result, new therapeutic options for the treatment of obesity are clearly warranted. Recent research has focused on th...

Plasma levels of interleukin (IL)-6, soluble IL-6 receptor, soluble gp130, leukemia inhibitory factor (LIF), and ciliary neutrophic factor (CNTF) were analyzed in 32 patients with severe malaria. Ten had renal failure, 8 had cerebral malaria, and 14 had other causes of severity. Before treatment, the IL-6 and soluble IL-6 receptor plasma levels were significantly higher in persons with cerebral...

Ciliary ganglion (CG) neurons undergo target-dependent cell death during embryonic development. Although ciliary neurotrophic factor (CNTF) was identified in vitro by its ability to support the survival of chick CG neurons, its function as a target-derived neurotrophic factor has been questioned by those working on mammalian-derived forms of CNTF. We have purified and cloned a chicken CNTF [chC...

Interleukin 6 (IL-6) is a major growth factor for tumor plasma cells involved in human multiple myeloma (MM). In particular, human myeloma cell lines (HMCL), whose growth is completely dependent on addition of exogenous IL-6, can be obtained reproducibly from every patient with terminal disease. Four cytokines, ciliary neurotropic factor (CNTF), IL-11, leukemia inhibitory factor (LIF), and onco...

Ciliary neurotrophic factor (CNTF) has been purified 35,000-fold to homogeneity from rabbit sciatic nerves using its ability to promote the survival of chick embryo ciliary ganglion neurons as the bioassay. The purification involved a combination of acid treatment, ammonium sulfate fractionation, hydrophobic interaction chromatography, chromatofocusing, preparative sodium dodecyl sulfate-polyac...
