The TEK receptor tyrosine kinase is expressed almost exclusively in endothelial cells in mice, rats, and humans. (TEK is closely related to the TIE receptor tyrosine kinase.) This receptor possesses a unique extracellular domain containing 2 immunoglobulin-like loops separated by 3 epidermal growth factor-like repeats that are connected to 3 fibronectin type III-like repeats. The ligand for the receptor is angiopoietin-1. TEK has also been suggested as a marker … Webb31 jan. 2024 · A signaling axis in the vascular endothelium, the Angiopoietin-Tie2 pathway, may play a central role in the abrupt transition from microvascular integrity to pathological disruption. Tie2 signaling is highly active when vessels are in their quiescent state: stable junctions, anti-inflammatory, and anti-coagulant. inspiracni texty
