Molecular analysis of behavior by gene transfer into neurons with herpes simplex vectors.
One goal of neuroscience is to define the molecular and cellular basis for behavior and neurological diseases. A novel approach to this problem is based on the use of viral vectors to transfect specific genes into specific brain cell populations. This review focuses on herpes simplex-based vectors. Major advances have recently been made to improve the characteristics of these vectors, in particular to reduce their toxicity, to modulate the greatness and the time-course of transgene expression, to precisely target specific cell populations, and to transfer multiple genes. Much remains to be done to obtain robust and prolonged transgene expression. However, specific alterations in the behavior and in disease models have already been described following the herpes simplex vector-mediated expression of specific genes within highly localized brain areas. Therefore, this research strategy is likely to provide new clues on the cellular and molecular basis of behavior and of neurological diseases.
