Swedish scientists tested a cocktail of molecules in mice with Parkinson-like symptoms.
After treatment, the mice’s symptoms appeared to improve.
The revolutionary approach may overtake brain cell transplants, which was previously thought to be the only hope of a cure.
According to study author Dr Ernest Arenas, this new treatment will not require the immune system-suppressing drugs needed in transplants.
The therapy makes dopamine-producing cells from those already in the brain, meaning patients will not reject them, which is a risk with transplants, he said.
Although the potential cure could transform Parkinson’s treatment, scientists warn further animal studies are needed before the approach can be tried in humans.
Professor David Dexter, deputy director, Parkinson’s UK said: ‚Further development of this technique is now needed,‘ the BBC reported.
‚If successful, it would turn this approach into a viable therapy that could improve the lives of people with Parkinson’s and, ultimately, lead to the cure that millions are waiting for.‘
This comes after scientists from the University of Oxford found infection with hepatitis B and C viruses raises the risk of Parkinson’s by up to 76 per cent.
This is thought to be due to the viruses targeting the motor system once they leave the liver.
