Autophagy in Chronic Kidney Diseases

Area of Science:

• Cell Biology
• Nephrology
• Molecular Medicine

Background:

• Autophagy is a fundamental cellular process for degrading and recycling damaged components.
• It plays a crucial role in maintaining kidney physiology and homeostasis.
• Autophagy dysfunction is implicated in various kidney diseases, including acute kidney injury, chronic kidney disease, diabetic nephropathy, and polycystic kidney disease.

Purpose of the Study:

• To review the current understanding of autophagy in kidney pathophysiology.
• To discuss the role of autophagy in different kidney diseases and drug-induced nephrotoxicity.
• To explore therapeutic strategies targeting autophagy for kidney disease treatment.

Main Methods:

• Literature review of current concepts and evidence on autophagy in kidney diseases.
• Analysis of molecular mechanisms linking autophagy to kidney cell function and dysfunction.
• Synthesis of findings on autophagy's role in acute kidney injury, chronic kidney disease, drug toxicity, and aging kidneys.

Main Results:

• Autophagy modulation is linked to acute and chronic kidney diseases, diabetic nephropathies, and polycystic kidney diseases.
• Oxidative stress, inflammation, and mitochondrial dysfunction impact autophagy, leading to cellular recycling defects.
• Impaired autophagy in chronic kidney disease is not reversed by hemodialysis; drug-induced autophagy alterations offer insights into nephrotoxicity.

Conclusions:

• Autophagy is a critical player in kidney health and disease, with its dysregulation contributing to various nephropathies.
• Understanding autophagy's role provides opportunities to manage drug-induced kidney damage and develop novel therapeutic interventions.
• Targeting the autophagy system holds promise for treating a range of kidney diseases.
