1 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.

A liposome-exosome hybrid vesicle loaded with ciliary neurotrophic factor, its preparation method and application

This invention relates to the field of biomedicine, specifically to a liposome-exosome hybrid vesicle loaded with ciliary neurotrophic factor (CNTF), its preparation method, and its application. This multifunctional hybrid vesicle comprises human umbilical cord mesenchymal stem cell exosomes and liposomes, with a particle number ratio of 1-4:1-4 for the human umbilical cord mesenchymal stem cell exosomes to liposomes. It is an innovative delivery system with dual functions, retaining the inherent natural targeting and biocompatibility of exosomes while integrating the efficient encapsulation and protection capabilities of liposomes for CNTF. In application, this multifunctional hybrid vesicle is used in a treatment model of traumatic optic nerve injury. This system can deliver bioactive CNTF to the injury site, effectively promoting the survival of retinal ganglion cells and axonal regeneration, demonstrating excellent therapeutic effects and providing a highly promising strategy for the treatment of central nervous system diseases such as optic nerve injury.
