Autophagy and Lysosome Storage Disorders.

Area of Science:

• Biochemistry
• Genetics
• Cell Biology

Background:

• Lysosomal storage disorders (LSDs) are a group of over 70 genetic metabolic diseases.
• These disorders stem from gene mutations affecting lysosomal enzyme or protein function.
• Accumulation of undigested macromolecules causes cellular stress and systemic damage, particularly affecting the nervous system.

Purpose of the Study:

• To review the underlying mechanisms of LSDs.
• To highlight the role of impaired autophagy in LSD pathogenesis.
• To explore autophagy modulation as a therapeutic strategy for LSDs.

Main Methods:

• Literature review of genetic metabolic diseases.
• Analysis of lysosomal function and cellular degradation pathways.
• Examination of the relationship between autophagy and LSDs.

Main Results:

• Defective lysosomal function leads to the accumulation of undigested materials.
• Impaired autophagy is a common pathogenic mechanism across various LSDs.
• Autophagy dysfunction contributes to cellular, tissue, and organ damage.

Conclusions:

• Lysosomal storage disorders result from genetic defects causing macromolecular accumulation.
• Autophagy impairment is a central mechanism in LSDs.
• Targeting and modulating autophagy holds potential as a novel therapeutic approach for LSDs.
