# Mitophagy in Age-Dependent Neurodegeneration

## TL;DR

This paper reviews how mitophagy, the process of removing damaged mitochondria, declines with age and contributes to neurodegenerative diseases like Alzheimer's and Parkinson's.

## Contribution

The paper provides a comprehensive overview of mitophagy pathways and their dysregulation in aging, highlighting potential therapeutic targets.

## Key findings

- Mitophagy declines with age, leading to mitochondrial dysfunction in neurons.
- Dysregulated mitophagy is linked to neurodegenerative diseases like Alzheimer's and Parkinson's.
- Understanding mitophagy pathways could lead to new therapies for age-related neurological conditions.

## Abstract

Mitochondrial dysfunction is one of the pathogenetic mechanisms of neuronal
damage during aging. The high energy dependence of neurons makes them
particularly vulnerable to age-related changes accompanied by oxidative stress
and impaired energy metabolism. The maintenance of a pool of functional
mitochondria is regulated by mitophagy, which ensures the utilization of
damaged organelles, thereby preventing the progression of mitochondrial
dysfunction. Brain aging is accompanied by a reduced level of activity of
metabolic processes, aggravated mitochondrial dysfunction, and an increased
risk of developing neurodegenerative diseases such as Alzheimer’s disease
and Parkinson’s disease. This review highlights the molecular and
signaling pathways of mitophagy and its dysregulation during physiological and
pathological aging, which is of particular interest for identifying
pharmaceutical targets and developing potential therapies for neurodegenerative
conditions.
