Abstract:
Autophagy is the major catabolic pathway involved in removing and recycling damaged macromolecules and organelles and several evidences suggest that dysfunctions of this pathway contribute to the onset and progression of central and peripheral neurodegenerative diseases. Diabetic retinopathy (DR) is a serious complication of diabetes mellitus representing the main preventable cause of acquired blindness worldwide. DR has traditionally been considered as a microvascular disease, however this concept has evolved and neurodegeneration and neuroinflammation have emerged as important determinants in the pathogenesis and evolution of the retinal pathology. Here we review the role of autophagy in experimental models of DR and explore the potential of this pathway as a target for alternative therapeutic approaches.
Insights
Autophagy dysfunction contributes to neurodegenerative diseases like diabetic retinopathy (DR). Targeting this cellular recycling process may offer new therapeutic strategies for DR, a leading cause of blindness.
Area of Science:
- Cellular Biology
- Ophthalmology
- Neuroscience
Background:
- Autophagy is a key cellular process for degrading damaged components.
- Dysfunctional autophagy is linked to neurodegenerative diseases.
- Diabetic retinopathy (DR) involves retinal neurodegeneration and inflammation beyond microvascular damage.
Purpose of the Study:
- To review the role of autophagy in experimental models of diabetic retinopathy (DR).
- To explore autophagy as a potential therapeutic target for DR.
Main Methods:
- Literature review of experimental models of DR.
- Analysis of studies investigating autophagy in the context of DR pathogenesis.
Main Results:
- Evidence suggests autophagy plays a significant role in DR.
- Autophagy modulation impacts retinal neurodegeneration in DR models.
Conclusions:
- Autophagy is implicated in the neurodegenerative aspects of DR.
- Targeting autophagy presents a promising avenue for novel DR therapies.
