Abstract

The present invention relates to the construction method and application of one kind of human neurenergen-3 receptor gene (human TrkC gene) recombined adenovirus expressing vector. The basic scheme of the present invention includes: designing and synthesizing primer, RT-PCR process, construction and identification of cloned shuttle vector pShuttle-TrkC, construction and identification of recombined adenovirus vector pAdeno-TrkC, 293 cell packaging, identification of recombined adenovirus, bioactivity detection of human neurenergen-3 receptor gene recombined adenovirus expressing vector and other steps. The present invention is superior in that one kind gene recombined adenovirus expressing vector is selected to promote the survival of damaged central neure and the regeneration of axone, to promote nerve stem cell to differentiate into more neures to replace damaged or dead neures.

Description

technical field [0001] The invention relates to a method for constructing a recombinant adenovirus expression vector, in particular to a method for constructing an adenovirus expression vector recombined with human neurotrophin-3 receptor gene (human TrkC gene) and its application. Background technique [0002] Neurotrophic factors are a class of chemical factors that can support the survival of neurons in the body, promote their growth, differentiation, and maintain their functions. Before neurotrophic factors exert cytological effects on their target cells, they must first bind to receptors on the target cells. Currently known neurotrophic factors have two receptors: tyrosine protein kinase receptor (high affinity receptor) and p75 receptor (low affinity receptor). Tyrosine protein kinase receptor is a receptor encoded by the proto-oncogene Trk, also known as Trk receptor. Trk receptors can be divided into three types: TrkA, TrkB and TrkC. [0003] Neurotrophic factors ...
