背景介绍
Ciliary Neurotrophic Factor (CNTF) is a potent survival factor for neurons and oligodendrocytes. CNTF has also been shown to prevent the degeneration of motor axons after axotomy. CNTF is highly conserved across species and exhibits cross-species activities. Human and rat CNTF share approximately 83% homology in their Protein sequence. CNTF is structurally related to IL6, IL11, LIF and OSM. All of these four helix bundle Cytokines share gp130 as a signal transducing subunit in their Receptor complexes. CNTF, like FGF acidic, FGF basic, and PD-ECGF (platelet-Derived endothelial cell Growth Factor), does not possess a signal sequence that would allow secretion of the factor by classical secretion pathways. The mechanism underlying the release of CNTF is unknown.
