Selective Autophagy as a Potential Therapeutic Target in Age-Associated Pathologies

Area of Science:

• Cellular Biology
• Molecular Biology
• Gerontology

Background:

• Progressive accumulation of damaged cellular components is a hallmark of aging and contributes to age-related diseases.
• Autophagy, a fundamental catabolic process, is crucial for recycling cellular material across various tissues and organs.
• Dysfunctional autophagy, particularly selective autophagy, is increasingly linked to severe pathologies and aging processes.

Purpose of the Study:

• To elucidate the modes and mechanisms of selective autophagy.
• To review experimental evidence linking autophagy perturbations to severe pathologies.
• To identify potential pharmacological targets for therapeutic interventions in autophagy-related disorders.

Main Methods:

• Literature review of selective autophagy mechanisms.
• Survey of experimental data on dysfunctional autophagy.
• Analysis of identified pharmacological targets for therapeutic potential.

Main Results:

• Selective autophagy ensures cellular homeostasis by precisely degrading damaged constituents.
• Polymorphisms in genes regulating selective autophagy are associated with aging and age-related disorders.
• Evidence highlights severe pathologies arising from impaired autophagy.

Conclusions:

• Pharmacological modulation of autophagic flux presents a promising therapeutic strategy for age-related diseases.
• Targeting specific pathways in selective autophagy may alleviate cellular cargo burden and associated pathologies.
• Understanding and manipulating selective autophagy is key to combating age-related cellular dysfunction.
