Mechanism of Focal Adhesion Kinase Mechanosensing
Mechanosensing at focal adhesions regulates vital cellular processes. Here, we present results from molecular dynamics (MD) and mechano-biochemical network simulations that suggest a direct role of Focal Adhesion Kinase (FAK) as a mechano-sensor. Tensile forces, propagating from the membrane through the PIP2 binding site of the FERM domain and from the cytoskeleton-anchored FAT domain, activate...
متن کاملFocal adhesion kinase is involved in mechanosensing during fibroblast migration.
Focal adhesion kinase (FAK) is a non-receptor protein tyrosine kinase localized at focal adhesions and is believed to mediate adhesion-stimulated effects. Although ablation of FAK impairs cell movement, it is not clear whether FAK might be involved in the guidance of cell migration, a role consistent with its putative regulatory function. We have transfected FAK-null fibroblasts with FAK gene u...
متن کاملUniversal kinetics for engagement of mechanosensing pathways in cell adhesion
When plated onto substrates, cell morphology and even stem cell differentiation are influenced by the stiffness of their environment. Stiffer substrates give strongly spread (eventually polarized) cells with strong focal adhesions, and stress fibers; very soft substrates give a less developed cytoskeleton, and much lower cell spreading. The kinetics of this process of cell spreading is studied ...

The basic physiology of leucocyte emigration from the intravascular space into the tissues is now known to be dependent on a class of cell surface molecules that have come to be known as adhesion molecules. Many cell-cell interactions are dependent on adhesion and signal transduction via the various adhesion molecules, particularly the integrins. The study of the functions of these molecules ha...
متن کاملSoluble Intercellular Adhesion Molecule
Previous studies have suggested that intercellular ad¬ hesion molecule 1 (ICAM-1, CD54) may be involved in the pathogenesis ofasthma. In addition, a soluble form of ICAM-1 (sICAM-1) has been detected in increased concentrations in the sera of patients with certain in¬ flammatory conditions. To determine whether bron¬ chial asthma is associated with increased levels of sICAM-1 in serum and to as...
