Mitochondrial dysfunction is key in Alzheimer's disease (AD) pathogenesis. This review examines how altered mitochondrial dynamics and mitophagy contribute to neuronal dysfunction in AD.
Area of Science:
- Neuroscience
- Cell Biology
- Pathology
Background:
- Mitochondrial dysfunction is an early hallmark of Alzheimer's disease (AD).
- Neurons heavily rely on mitochondrial function due to their high metabolic activity.
- Mitochondrial dynamics (fusion/fission) and mitophagy are crucial for maintaining mitochondrial health.
Purpose of the Study:
- To review recent findings on mitochondrial dynamics and mitophagy alterations in Alzheimer's disease.
- To discuss the impact of these changes on mitochondrial quality control and neuronal dysfunction in AD.
Main Methods:
- Literature review of studies on mitochondrial dynamics and mitophagy in AD.
- Analysis of research on AD brain and mouse models.
Main Results:
- Significant alterations in mitochondrial dynamics (fusion/fission) are observed in AD.
- Dysfunctional mitophagy pathways are implicated in AD pathogenesis.
- These abnormalities impair mitochondrial quality control in vulnerable neurons.
Conclusions:
- Altered mitochondrial dynamics and mitophagy are critical contributors to mitochondrial dysfunction in Alzheimer's disease.
- Targeting these pathways may offer therapeutic strategies for AD.

Sorting of outer membrane proteins:
Mitochondrial outer membrane proteins are of two types: the transmembrane, beta-barrel porins, and the membrane-anchored, alpha-helical proteins. Beta-barrel porin precursors are translocated by the TOM complex and inserted into the outer mitochondrial membrane by the SAM complex. In contrast,...
