Mitochondrial Dynamics Dysregulation In Neurodegeneration is an important cell type in the neurobiology of neurodegenerative diseases. This page provides detailed information about its structure, function, and role in disease processes.
Mitochondrial dynamics—the balance between fusion and fission—is essential for neuronal health. Dysregulation of these processes contributes to neurodegeneration by impairing mitochondrial quality control, energy metabolism, and calcium homeostasis.
- MFN1/2: Outer membrane GTPases
- OPA1: Inner membrane fusion
- Mitofusins: Tethering proteins
