New research published this week in the Journal of Experimental Medicine suggests that injections of a molecule produced by a virus may have great potential for developing treatments that can slow, stop or even reverse Parkinson's.
Viruses are the culprits behind many human infectious diseases - such as the common cold and HIV.
But their ability to get into our cells and affect the way they work makes them an attractive target for scientists who can manipulate them to treat conditions like Parkinson's.
In this new study - funded by the Michael J. Fox Foundation - researchers showed that injections of a tiny viral molecule called p137 protected rats from nerve cell loss and improved their mobility.
