β3-Integrin-Dependent Fibrillogenesis of Macromolecular RGD-Ligands in Relation to Biome-chanic Stress
Integrins and their ligands are prominent players regulating interactions of the extracellular environment and cellular functions. Sensing the biomechanic microenvironment integrins bidirectionally transmit conformational changes across the membrane. The resulting signals modulate cytoskeletal functions (outside-in signalling) and vice versa the cytoskeleton regulates the molecular relationship between receptor molecules and their ligands (inside-out signalling). Thus, mechanotransduction of ligand-occupied integrins regulate stable but flexible interactions between neighbouring cells. This is particular true for cells which are exposed to shear forces. The integrins αIIbβ3 and αvβ3 both incorporate the same β-subunit. β3-integrins bind RGD containing ligands e.g. fibronectin (Fn), fibrinogen and von Willebrand Faktor (vWF). Whereas Fn is a core component of extracellular matrices fibrinogen and vWF are plasmatic proteins. Fn and vWF are of a compact structure. They are unfolded by either shear stress or β3-integrins and cell traction forces modulate their fibrillogenesis. In our project we focus on the dynamic of β3-integrin-ligand interaction in response to conformational and functional changes upon exposure to shear stress. In a flow model we use human platelets or cell lines expressing β3-integrins to measure fibrillogenesis of Fn in response to mechanotransduction. Therefore, fluorescently labelled Fn is used to measure e.g. disappearance of fluorescence resonance energy transfer (FRET). To assess the specific role of the β3-subunit, two isoforms (Leu33 and Pro33) are compared because the Pro33 isoform is a risk determinant of acute coronary syndromes due to a prothrombotic characteristics like enhanced platelet adhesion and increased outside-in signaling.
