Research Abstract

We produced various types of fusion glycoproteins, in which the junction between the RVG and VSVG glycoprotein segments diverged in the membrane-proximal region of RVG, and generated HIV-1-based lentiviral vectors pseudotyped with these fusion glycoproteins. We then tested the efficiency of the pseudotyped vectors for the in vivo gene transfer through retrograde transport, comparing that of the NeuRet vector with FuG-C. We found a novel type of fusion glycoprotein, termed type E (FuG-E), that showed improved efficiency of retrograde gene transfer while retaining the property of neuron-specific transduction. This NeuRet vector with FuG-E will provide a powerful tool for genetic treatment of neurological and neurodegenerative diseases and for the study of neural circuit mechanisms underlying various brain functions.
