Podocyte Death in Diabetic Kidney Disease: Potential Molecular Mechanisms and Therapeutic Targets

Area of Science:

• Nephrology and Diabetes Complications
• Cellular Biology and Pathophysiology

Background:

• Cell death is crucial for tissue homeostasis but aberrant cell death contributes to disease.
• Diabetic kidney disease (DKD) is a major diabetes complication characterized by high mortality.
• Podocyte loss and detachment are central pathological features driving DKD progression.

Purpose of the Study:

• To review the mechanisms of various cell death modalities in podocytes within the context of DKD.
• To explore how different cell death pathways contribute to the pathogenesis and progression of DKD.
• To highlight current research and future therapeutic strategies targeting podocyte cell death in DKD.

Main Methods:

• Comprehensive literature review of basic and clinical research studies.
• Analysis of mechanisms including apoptosis, necrosis, autophagy, pyroptosis, ferroptosis, cuproptosis, and podoptosis.
• Focus on studies investigating the role of these cell death pathways in podocytes during DKD.

Main Results:

• Multiple cell death pathways (apoptosis, necrosis, pyroptosis, ferroptosis, cuproptosis, podoptosis) are implicated in podocyte injury in DKD.
• These diverse cell death mechanisms collectively contribute to podocyte loss and kidney damage.
• Current research identifies specific pathways as potential therapeutic targets.

Conclusions:

• Targeting specific podocyte cell death pathways presents a promising therapeutic avenue for DKD.
• Further research is needed to fully elucidate the roles of each cell death mode and develop effective treatments.
• Interventions aimed at modulating podocyte cell death could mitigate DKD progression and improve patient outcomes.
