Cell migration is a coordinated process that involves rapid changes in the dynamics of
actin filaments, together with the formation and disassembly of cell adhesion sites.
External stimuli that control cell migration are transduced into intracellular
biochemical signals through the interactions of ...
Integrins are heterodimeric adhesion receptors composed
of alpha- and beta-subunits. It is known that at least 18 distinct alpha subunits and 8
or more beta subunits lead to generation of 24 alpha/beta heterodimeric receptors. Most
integrins recognize extracellular matrix (ECM) proteins, such ...
The binding of Plasminogen activator, urokinase (PLAU
(UPA)) to its glycosyl-phosphatidyl-inositol (GPI) anchored Plasminogen
activator, urokinase receptor (PLAUR (UPAR) (uPAR)) mediates
a variety of functions including vascular homeostasis, inflammation and tissue repair
The integrin family of transmembrane adhesion receptors mediates both cell-cell and
cell- extracellular matrix (ECM) adhesion. One important, rapid and reversible mechanism
for regulating adhesion is increasing the affinity of integrin receptors for their
extracellular ligands (integrin activation). ...
Extracellular matrix (ECM) remodeling is involved in normal physiological processes,
such as embryonic development, reproduction, proliferation, cell motility and adhesion,
wound healing, angiogenesis, as well as in disease processes, such as arthritis and
metastasis. Matrix metalloproteinases (MMPs) ...
Contacts between endothelial cells are of great importance for blood vessel
formation.The formation and maintenance of endothelial cell
contacts require the complex interplay of plasma membrane proteins, cytoskeleton
components, and signaling molecules. Some of these molecules are specifically ...
