Abstract: The present invention is related to compositions and methods for the delivery of nucleic acids to neurons in a mammal, and uses thereof. The present invention specifically discloses the use of compounds that cause synaptic nerve sprouting to increase neuron retrograde transport of a vector or a product (a polypeptide or a nucleic acid for example) in a mammal. The invention is also based on the use of a compound that interacts with synaptosomal associated proteins to increase neuron retrograde transport of a vector or a product such as one cited above in a mammal. The invention also relates to a product comprising a viral vector comprising a transgene and a compound that causes synaptic nerve sprouting, for sequential use for delivering said transgene to neurons by retrograde transport and its uses for the preparation of a composition used as a treatment in several neurological disorders.
