Diabetic vascular complications: pathophysiology, biochemical basis and potential therapeutic strategy

Area of Science:

• Endocrinology
• Vascular Biology
• Diabetology

Background:

• Diabetic vascular complications contribute significantly to end-stage renal failure, blindness, neuropathy, and atherosclerosis.
• These complications lead to substantial disability and mortality in diabetic patients.
• While intensive glucose control benefits microvascular outcomes, macrovascular complications involve insulin resistance and postprandial hyperglycemia.

Purpose of the Study:

• To summarize the molecular mechanisms underlying diabetic vascular complications.
• To explore potential therapeutic interventions for preventing these disorders, even when hyperglycemia is difficult to control.

Main Methods:

• Review of molecular mechanisms initiated by chronic hyperglycemia.
• Analysis of pathways including advanced glycation end products, protein kinase C, polyol pathway, and reactive oxygen species.
• Examination of the role of vascular inflammation, gene expression, and cellular activation.

Main Results:

• Chronic hyperglycemia initiates vascular complications through multiple molecular pathways.
• These pathways regulate vascular inflammation, alter growth factor and cytokine expression, and activate platelets and macrophages.
• High glucose plays a central role in the development and progression of diabetic vascular complications.

Conclusions:

• Understanding the molecular basis of diabetic vascular complications is crucial.
• Targeting these mechanisms may offer therapeutic strategies to prevent or mitigate complications.
• Novel interventions are needed to manage hyperglycemia and its vascular consequences effectively.
