Function and interactions of integrins
WebApr 10, 2024 · EV binding by recipient cells is mediated by protein–protein, lipid–protein, lipid–lipid, and glycan–protein interactions. For example, tetraspanins, integrins, various adhesion molecules, fibronectins, and phosphatidylserine are known to be involved in the process of EV binding. WebOne of the major receptors of ECM-cell interactions is integrins. Integrins are heterodimers involved in transmitting extracellular cues into cellular signaling [ 16 , 326 ]. During development and in some pathological conditions, specific integrins are expressed and these influence specific cellular activities such as migration, proliferation ...
