Integrin signaling emphysema
Nettet13. aug. 1999 · The ECM exerts profound control over cells. The effects of the matrix are primarily mediated by integrins, a family of cell surface receptors that attach cells to the matrix and mediate mechanical and chemical signals from it. These signals regulate the activities of cytoplasmic kinases, growth factor receptors, and ion channels and control … Nettetof focal adhesions and integrin signaling (4, 5). Because of its ability to associate into oligomers, caveolin-1 may help integrins to cluster on the plasma membrane. Integrin-associated structural and signaling proteins also aggregate with the integrins, and signal-ing is facilitated by the resulting high local concentrations of these proteins ...

The α6β4 integrin is an essential component of hemidesmosomes in keratinocytes. Integrins not only connect cells mechanically to the surrounding environment but also NettetIntegrin members are expressed on virtually every cell and provide essential links between the extracellular environment and intracellular signaling pathways. In doing so, integrins play a role in most essential cell behaviors, including cell survival, apoptosis, differentiation, and transcriptional regulation.
