Summary

This summary is machine-generated.

Integrins are cell adhesion receptors that also act as signaling molecules in epithelial cells. These signals regulate cell behavior and responses to tissue injury, inflammation, and remodeling.

Main Results:

Integrins on epithelial cells function as signaling molecules, detecting cell-matrix interactions.
Integrin-initiated signals influence epithelial cell differentiation, proliferation, survival, and gene expression.
Altered integrin ligand concentrations during injury and inflammation impact epithelial cell responses.

Conclusions:

Integrins are crucial signaling molecules in epithelial cells, beyond their adhesive roles.
Integrin signaling is vital for epithelial cell homeostasis and response to tissue damage.
Targeting integrin signaling pathways may offer therapeutic strategies for epithelial-related diseases.
