Autophagy and lysosomal dysfunction in diabetes and its complications

Area of Science:

• Cellular Biology
• Metabolism
• Endocrinology

Background:

• Autophagy is vital for cellular energy balance and organelle function, including endoplasmic reticulum (ER) and mitochondria.
• Dysregulated autophagy is implicated in aging, environmental stress, and genetic factors, contributing to diabetes via beta-cell dysfunction and inflammation.
• Lysosomal dysfunction, driven by metabolic stress, exacerbates diabetes and its complications, such as diabetic kidney diseases (DKDs).

Purpose of the Study:

• To explore the etiological role of disrupted autophagy and lysosomal function in the development of diabetes.
• To discuss the potential of modulating autophagy and lysosomal activity as a novel therapeutic approach for diabetes and its associated complications.

Main Methods:

• Literature review and synthesis of existing research on autophagy, lysosomal function, and metabolic diseases.
• Analysis of the molecular mechanisms linking dysregulated autophagy and lysosomal dysfunction to diabetes pathogenesis.
• Discussion of potential therapeutic interventions targeting autophagy and lysosomal pathways.

Main Results:

• Dysfunctional autophagy contributes to beta-cell failure and metabolic inflammation, key factors in diabetes.
• Lysosomal impairment, caused by metabolic overload, worsens diabetes and promotes complications like DKDs.
• Evidence suggests a strong link between impaired autophagic-lysosomal pathways and the progression of diabetic pathologies.

Conclusions:

• Autophagy and lysosomal dysfunction are critical etiological factors in diabetes and its complications.
• Targeting autophagy and lysosomal pathways presents a promising therapeutic avenue for managing diabetes and preventing its long-term consequences.
