Background:

• Vascular endothelial growth factor (VEGF) and its receptors (VEGFRs) are crucial regulators of angiogenesis and lymphangiogenesis.
• Dysregulation of VEGF/VEGFR pathways is implicated in various diseases, including cancer, arthritis, and ischemic conditions.
• Targeting VEGF/VEGFR interactions presents significant pharmaceutical opportunities.

Purpose of the Study:

• To review structure-based design strategies for peptides that mimic VEGF/VEGFR binding epitopes.
