The integrin α2 and integrin β1-Col I interaction plays an important part in bone cell differentiation. Nettet7. okt. 2024 · A subset of integrins, namely α1, α2, α10, and α11 exhibiting high collagen-binding affinity, are responsible for transducing biochemical or mechanical cues to regulate a variety of cellular functions such as cell proliferation, adhesion, migration, and hemostasis ( Adorno-Cruz and Liu, 2024 ).
Nettet1 integrins in collagens have been localized to the triple helical areas of the molecules (8, 9). One peptide sequence derived from the collagen achain has been reported to block integrin-collagen interaction (10), but in many studies it has been ineffective and it probably does not represent the actual binding site in collagen (11–13). More NettetIntegrins are transmembrane receptors that mediate the attachment between a cell and its surroundings, such as other cells or the extracellular matrix (ECM). In signal transduction, integrins pass information about the chemical composition and mechanical status of the ECM into the cell.

NettetIntegrins are a family of αβ heterodimeric cell surface receptors, responsible for cell-cell and cell-extracellular matrix interactions. The specificity and regulation of these interactions is critical to many biological processes, including embryonic cell migration, wound healing, and the immune response ( 1 ).
