NettetThese experiments yielded the protein name “integrin” as a description of the proteins' integral role in cellular adhesion processes and the transmembrane association between the extracellular matrix and the cytoskeleton. [2] LFA-1, a leukocyte integrin, was first discovered by Timothy Springer in mice in the 1980s. [2] 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…

NettetB VCAM-1. The vascular cell adhesion molecule VCAM-1 was originally identified as a cytokine-inducible adhesion molecule on human endothelial cells, mediating the binding to leukocytes and melanoma cells (178,203,204). VCAM-1 is a ligand for the α 4 β 1 integrin (VLA-4) and binds weakly to α 4 β 7 (102,205–207).
