77 results about "Ciliary neurotrophic factor" patented technology

Ciliary neurotrophic factor is a protein that in humans is encoded by the CNTF gene. The protein encoded by this gene is a polypeptide hormone and neurotrophic factor whose actions have mainly been studied in the nervous system where it promotes neurotransmitter synthesis and neurite outgrowth in certain neural populations including astrocytes. It is a hypothalamic neuropeptide that is a potent survival factor for neurons and oligodendrocytes and may be relevant in reducing tissue destruction during inflammatory attacks. A mutation in this gene, which results in aberrant splicing, leads to ciliary neurotrophic factor deficiency, but this phenotype is not causally related to neurologic disease. In addition to the predominant monocistronic transcript originating from this locus, the gene is also cotranscribed with the upstream ZFP91 gene. Cotranscription from the two loci results in a transcript that contains a complete coding region for the zinc finger protein but lacks a complete coding region for ciliary neurotrophic factor.

ActiveCN104001212APromote regenerationPromotes electrophysiological recoveryProsthesisFacial nerveCollagen scaffold
The invention discloses a method for preparing a collagen material for repairing peripheral nerve injury. The method comprises the following step: co-incubating a ciliary neurotrophic factor with a collagen binding domain (CBD-CNTF), a basic fibroblast growth factor with a collagen binding domain (CBD-bFGF) and an orderly collagen material to obtain a collagen material for repairing the peripheral nerve injury. According to the preparation method, two factors CBD-CNTF and CBD-bFGF are simultaneously crosslinked to the orderly collagen scaffold material, and the action of the double-factor peripheral nerve injury repairing collagen material in long-cross-section nerve injury repairing can be evaluated by establishing an animal peripheral nerve-facial nerve long cross-section injury model. Results prove that compared with single factor CBD-CNTF or CBD-bFGF functional collagen scaffold material, the double-factor peripheral nerve injury repairing collagen material can be used for better promoting regeneration of facial nerves and restoration of functions, and has a more important realistic guiding magnificence to application of clinical peripheral nerve injury repairing in the future.
