What is the Origin of VEGFR2 Pathway?

The receptor itself, also known as KDR or Flk-1, was identified in the late 20th century as a key member of the receptor tyrosine kinase family, specifically mediating the mitogenic and survival effects of VEGF. The "pathway" refers to the entire downstream cascade of events that follows ligand binding, establishing its origin as central to vascular biology and cell signaling research.

What is the Mechanism of VEGFR2 Pathway?

The mechanism begins with the binding of the VEGF-A ligand, which induces the dimerization of two VEGFR-2 receptors on the endothelial cell surface. Dimerization activates the intrinsic tyrosine kinase domain, leading to trans-autophosphorylation of specific tyrosine residues within the receptor's intracellular tail. These phosphorylated sites serve as docking stations for various signaling proteins, subsequently activating major cascades like the PI3K-Akt and PLCγ-PKC pathways to promote endothelial cell proliferation, migration, and survival.

VEGFR2 Pathway

Meaning

The VEGFR2 Pathway is the critical intracellular signaling cascade initiated by the Vascular Endothelial Growth Factor Receptor 2 (VEGFR-2), which serves as the principal receptor for the pro-angiogenic ligand, VEGF-A. This pathway is the master switch for angiogenesis, the process of forming new blood vessels from pre-existing ones, and is vital for physiological processes like wound healing and pathological conditions like tumor growth.
