Integrin-mediated mechanotransduction
Nettet20. sep. 2024 · We show that UTI89 takes advantage, via its CNF1 toxin, of integrin mechanoactivation to trigger its invasion into cells. We identified OPTN as a protein regulated by ECM stiffness whose function is required for bacterial invasion and integrin mechanical coupling and for stimulation of HACE1 E3 ligase activity towards the Rac1 … NettetIntegrins and extracellular matrix in mechanotransduction.

NettetIn this review, we have discussed how integrin-mediated mechanotransduction could be a linchpin factor in the causation and progression of autoimmune disorders. We have provided an insight on how tissue stiffness exhibits a positive correlation with the autoimmune diseases’ prevalence. Nettet1. mai 2016 · Integrins are transmembrane receptors with 2 subunits, α (alpha) and β (beta), which have distinct regulatory and signal-transducing functions, respectively. Both subunits contribute to connecting the cell to specific ECM proteins through transmembrane associations with the cytoskeleton.
