Integrins as cell surface receptors
NettetEndothelial cells and pericytes both express a subset of mammalian integrins including: the fibronectin receptors, α4β1, α5β1; the collagen receptors, α1β1, α2β1; the laminin receptors, α3β1, α6β1, and α6β4; and the osteopontin receptor, α9β1. 6,7 In addition pericytes also express α7β1 (laminin receptor) and α8β1 (osteopontin receptor) integrins. NettetIntegrins are transmembrane glycoproteins occurring in cell membranes as hetorodimers made of two subunits, alpha and beta, associated with noncovalent …

Nettetthe basal cell surface and therefore were not available to serve as pilus receptors. Antibody-labelled a 1-, a 2- and b 1-integrins were only faintly visible on the surface of … NettetCells respond to extracellular mechanical forces through the assembly of integrin adhesion complexes (IACs) that provide a scaffold through which cells sense and transduce responses to those forces. IACs are composed of transmembrane integrin receptors that bind to extracellular matrix (ECM) proteins externally and connect with the actomyosin …
