Scientists from the Institute of Nano Science and Technology (INST) Mohali, an autonomous institute of the Department of Science and Technology (DST), have showed that nano-formulation of melatonin -- the hormone produced by the brain in response to darkness -- could provide therapeutic solution for Parkinson's disease.

Parkinson's disease (PD) is one of the most common neurological disorders caused by the death of dopamine-secreting neurons in the brain due to aggregation of synuclein protein inside it.
