- Parkinson's disease (PD) is a neurodegenerative disorder affecting motor function, leading to tremors, rigidity, bradykinesia, and postural instability.
- PD involves the degeneration of dopaminergic neurons in the substantia nigra pars compacta (SNpc) and α-synuclein protein deposits.
- Miro1, a mitochondrial Rho GTPase, regulates neuronal energy transport, mitochondrial motility, and quality control in the CNS.
- Miro1 interacts with PD-related proteins like PINK1, Parkin, and LRRK2, influencing mitochondrial function.
- Dysregulation or mutations in Miro1 disrupt mitochondrial transport, mitophagy, and calcium homeostasis, contributing to oxidative stress and neurodegeneration.
- Miro1 dysfunction is linked to α-synuclein aggregation and increased risk of PD development.
- The review highlights Miro1's role in PD pathophysiology and explores its potential as a therapeutic target.
