Role of autophagy in chronic kidney diseases

Area of Science:

• Nephrology
• Cell Biology
• Molecular Medicine

Background:

• Chronic kidney diseases (CKD) represent a significant global health challenge, characterized by progressive kidney fibrosis, remodeling, and cell loss.
• Autophagy, a fundamental cellular process for degrading damaged components, is crucial for maintaining cellular homeostasis and responding to stress.
• Evidence suggests a link between dysfunctional autophagy and the pathogenesis of CKD.

Purpose of the Study:

• To review the current understanding of autophagy's role in the development and progression of chronic kidney diseases.
• To highlight the molecular mechanisms by which autophagy influences kidney fibrosis and cell survival in CKD.
• To explore the therapeutic potential of modulating autophagy for CKD treatment.

Main Methods:

• Literature review of preclinical and clinical studies investigating autophagy in CKD models and patients.
• Analysis of research on the molecular pathways regulating autophagy and their implications in kidney disease.
• Synthesis of evidence linking impaired autophagy to kidney fibrosis, inflammation, and cell death in CKD.

Main Results:

• Impaired autophagic activity is consistently observed in various forms of CKD.
• Dysfunctional autophagy exacerbates kidney fibrosis, tubular atrophy, and glomerular damage.
• Autophagy plays a critical role in cellular adaptation to kidney injury and maintaining renal function.

Conclusions:

• Autophagy is a key player in the pathogenesis and progression of chronic kidney diseases.
• Targeting autophagy signaling pathways presents a promising therapeutic avenue for CKD.
• Further research into autophagy modulation could lead to novel treatments for kidney fibrosis and related complications.
