Gene transfer into neurones for the molecular analysis of behaviour: focus on herpes simplex vectors.
The use of viral vectors to transfect genes into specific brain-cell populations is a novel approach that can be used to investigate the molecular and cellular basis of brain function. Ideal vectors should be targetable and capable of regulated transgene expression. From the viral vectors developed so far, this article focuses on herpes simplex virus 1 (HSV-1)-based vectors. HSV-1 vectors can be engineered for gene transfer to the brain, which makes them suitable for neuroscience research applications. In particular, genetic manipulations of the virus can almost eliminate toxicity and allow expression of multiple transgenes simultaneously. In some instances, transfection of selected neuronal populations is also possible. Specific alterations in behaviour and in disease models have been described after the viral-vector-mediated expression of specific genes within highly localized brain regions.
