Scientists are exploring a new way to treat Parkinson's disease (PD) using a special form of melatonin.
Here's a simplified explanation:
What is Parkinson's Disease? It's a brain disorder that affects movement. It's caused by the death of brain cells that make dopamine, a chemical messenger. This cell death is often linked to the buildup of a protein called synuclein. Current treatments only manage symptoms, not the underlying cause.
What is Melatonin? It's a hormone that helps regulate sleep. New research suggests it might also help clean up damaged parts inside cells, which could be helpful for PD.
What is Mitophagy? It's the cell's way of getting rid of damaged mitochondria (the cell's power plants). In PD, damaged mitochondria cause problems, so improving mitophagy could be a good treatment strategy.
What's the new approach? Scientists at INST Mohali have created a special "nano" form of melatonin. This means the melatonin is packaged in tiny particles (using human serum albumin or HSA) that help it get into the brain more effectively.
How does it work? The nano-melatonin helps boost mitophagy and create new, healthy mitochondria. It also protects brain cells from damage caused by toxins. This protection seems to be linked to increasing a protein called BMI1, which controls genes related to mitophagy.
What have they found? In experiments with rats, the nano-melatonin protected brain cells that are affected in PD. This suggests it could have a real benefit for people with the disease.
In simple terms: Scientists are trying to use melatonin, a sleep hormone, to treat Parkinson's disease. They've created a special "nano" version that works better in the brain. This nano-melatonin helps clean up damaged parts of brain cells and protect them from further damage, which could slow down or even stop the progression of PD. This is still early research, but it's a promising new direction for treatment
