Objective: To construct the recombinant vector of human single herpes virus (HSV) carried brain derived neurotrophic factor (BDNF) gene.
Methods: BDNF gene was acquired from rat brain tissue by RT-PCR, then was cloned into plasmid, and enveloped by HSV. The recombinant was used to transfer cultured cortical neurons. The number and neurite length of neurons were quantified. The BDNF level and subcellular localization were detected by ELISA and immunohistochemistry.
Results: HSV carried BDNF gene recombinant has been successfully constructed. The recombinant showed the bioactivity on the growth of cortical neurons. BDNF level was increased significantly in BDNF transferred group.
Conclusion: HSV carried BDNF gene recombinant, with the bioactivity, has been successfully constructed. This could provide the vector for the treatment of BDNF under disease condition base on transferring gene technique.
