Shared Synaptic Mechanism for Alzheimer's and Parkinson's Disease Unlocks New Treatment Possibilities
Parkinson's and Alzheimer's diseases are the two most prevalent neurodegenerative disorders, affecting millions globally. Recent research from the Okinawa Institute of Science and Technology (OIST), published in the Journal of Neuroscience, reveals a common molecular cascade between these diseases that causes synaptic dysfunctions, shedding light on how their symptoms develop.
Research Focus on Synaptic Dysfunction
The study explored how communication between brain cells across synapses is disrupted by the accumulation of disease-related proteins. The researchers identified a pathway that impairs synaptic vesicle recycling, a critical process for normal brain signaling.
Impact of Protein Accumulation on Brain Functions
Dimitar Dimitrov of OIST's Synapse Biology Unit explains, "Synapses are communication hubs in the brain involved in different neuronal circuits controlling different functions. Therefore, protein accumulation in synapses of one neuronal circuit may impact memory, while in another it may impair motor control."
