Integrin cycling
Nettet14. feb. 2013 · Cells regulate adhesion in response to internally generated and externally applied forces. Integrins connect the extracellular matrix to the cytoskeleton and provide cells with mechanical anchorages and signaling platforms. Here we show that cyclic forces applied to a fibronectin–integrin α5β1 bond switch the bond from a short-lived state … Nettet2. jan. 2009 · Although studies have shown that these cells are slow cycling, their molecular characteristics are not well understood. Using a whole-mount procedure, we show that whereas α 9 -integrin is present in a subset of the basal cells at the corneal limbus and absent in the central cornea, β 1 -, β 4 -, α 3 -, and α 6 -integrins are more …

NettetIntegrin-mediated adhesion initiates transduction of signals towards the cell interior and also regulates transmission of signals from growth factor receptors.2,3Thus, activation of most signaling pathways, including the E rk, PI 3-kinase, FAK, Src and Rho GTPases path- ways depend on integrins.4Integrin-mediated signal transduction regulates … Nettet15. okt. 2013 · Cell Cycle. 2013 Oct 15;12(20):3317-28. doi: ... Moreover, inhibition of autophagy slowed down the lysosomal degradation of internalized β1 integrins and promoted its membrane recycling. From these findings, we conclude that autophagy regulates cell migration, a central mechanism in cell development, ...
Integrins are transmembrane receptors that facilitate cell-cell and cell-extracellular matrix (ECM) adhesion. Upon ligand binding, integrins activate signal transduction pathways that mediate cellular signals such as regulation of the cell cycle, organization of the intracellular cytoskeleton, and movement of new receptors to the cell membrane. The presence of integrins allows rapid a…
