Herpes simplex virus: a tool for neuroscientists

Herpes viruses have received a great deal of attention due to their widespread and ubiquitous prevalence in the human population and to the diverse range of diseases caused as a result of an infection. During the last 20-25 years, many research laboratories have investigated the pathogenesis and molecular biology of these viruses; particularly herpes simplex virus (HSV). As a result of this research, HSV has begun to get the attention of neuroscientists. In fact, in the last few years there has been an explosion of research involving the use of HSV and related viruses as tools or model systems for different areas of neuroscience research. This brief review will describe several of these areas including demyelinating diseases, neuronal tracings, and genetic therapy.
