New York, March 5 : A smoking cessation drug — cytisine — may help treat Parkinson’s disease or stop its progression in women, say researchers, including an Indian-origin.
The study, published in the Journal of Neurochemistry, showed that, in an animal-based model, the drug reduces the loss of dopamine neurons in females, which indicates it as a potential evidence for the use of the drug to treat Parkinson’s disease.
“What cytisine does is it binds to target receptors but doesn’t activate them as efficiently as nicotine,” said researcher Rahul Srinivasan from the Texas A&M University in the US.
“It keeps the receptors ‘occupied’ and ‘chaperones’ them to the surface of the neuron. Since cytisine is a natural compound, is available quite freely and is pretty cheap, I decided to test this concept of chaperoning in an animal model of the disease to see if it works,” Srinivasan added.
For the study, the team artificially induced Parkinson’s disease in animal models.
During that time, they either gave them saline (salt water) or cytisine. Then, the researchers performed a series of behavioural experiments in order to see if there was any sort of protective effect on the animal models that were given cytisine.
