[Impaired angiogenesis and lymphangiogenesis in diabetes mellitus]

Area of Science:

• Vascular Biology
• Endocrinology
• Pathophysiology

Context:

• Diabetes mellitus is a global health concern associated with significant microvascular and macrovascular complications.
• Impaired formation of new blood vessels (angiogenesis) and lymphatic vessels (lymphangiogenesis) are increasingly recognized in diabetic pathology.
• Understanding these mechanisms is crucial for developing targeted therapeutic strategies.

Purpose:

• To review and synthesize recent findings on the molecular mechanisms underlying impaired angio- and lymphangiogenesis in diabetes mellitus.
• To elucidate the role of these vascular disorders in the pathogenesis of diabetes and its associated vascular complications.
• To highlight potential therapeutic targets for improving vascular function in diabetic patients.

Summary:

• Diabetes mellitus significantly disrupts the processes of angiogenesis and lymphangiogenesis.
• Key molecular pathways, including those involving growth factors (e.g., VEGF) and inflammatory mediators, are dysregulated in diabetic vasculature.
• These impairments contribute to diabetic retinopathy, nephropathy, neuropathy, and delayed wound healing.

Impact:

• Provides a comprehensive overview of current research on diabetes-related vascular dysfunction.
• Identifies critical knowledge gaps and suggests future research directions.
• Informs the development of novel therapeutic interventions aimed at restoring normal angio- and lymphangiogenesis in diabetes.
