What is the Origin of VEGFR2?

The discovery of VEGF and its receptors, including VEGFR2, occurred in the late 1980s and early 1990s as scientists sought to understand the factors controlling blood vessel growth. The term is an acronym that precisely identifies the molecule's function and type.

What is the Mechanism of VEGFR2?

Upon binding of the VEGF ligand, VEGFR2 dimerizes and undergoes autophosphorylation of its intracellular tyrosine residues, initiating a complex intracellular signaling cascade. This activation promotes endothelial cell proliferation, migration, and survival, driving the formation of new capillaries. Hormones, including estrogen, can modulate the expression of both VEGF and VEGFR2, thereby linking the endocrine system to the regulation of vascular health and tissue perfusion.

VEGFR2

Meaning

Vascular Endothelial Growth Factor Receptor 2, a high-affinity transmembrane receptor tyrosine kinase that is predominantly expressed on the surface of endothelial cells, the cells that line the interior of blood vessels. VEGFR2 is the primary mediator of the biological effects of Vascular Endothelial Growth Factor (VEGF), making it a crucial regulator of angiogenesis, the process of forming new blood vessels. Its signaling pathway is vital for tissue repair, reproduction, and is often overactive in various pathological conditions, including cancer.
