General description

Fibronectin is a high molecular weight extracellular adhesion molecule involved in many cellular processes, including tissue repair or wound healing, embryogenesis, blood clotting, and cell migration/adhesion. Fibronectin exists in two major forms: 1) as an insoluble glycoprotein dimer that serves as a linker in the extracellular matrix (ECM), and 2) as a soluble disulfide-linked dimer found in the plasma. The plasma form is synthesized by hepatocytes, and the ECM form is made by fibroblasts, chondrocytes, endothelial cells, macrophages, as well as certain epithelial cells. Fibronectin sometimes serves as a general cell adhesion molecule by anchoring cells to collagen or proteoglycan substrates. It can also serve to organize cellular interaction with the ECM by binding to different components of the ECM and to membrane-bound fibronectin receptors on cell surfaces. The immunogen for fibronectin polyclonal antibody AB2033 is purified mouse plasma. The antibody shows less than 0.1% reactivity with mouse laminin, and collagen types I, III, and IV by radioimmunoassay.

The classical view of the immune system has changed by the discovery of novel T-helper (Th) subsets, including Th17 (IL-17A-producing cells). IL-17A participates in immune-mediated glomerulonephritis and more recently in inflammatory pathologies, including experimental renal injury. Peritoneal dialysis patients present...

Birthdate-dependent neuronal layering is fundamental to neocortical functions. The extracellular protein Reelin is essential for the establishment of the eventual neuronal alignments. Although this Reelin-dependent neuronal layering is mainly established by the final neuronal migration step called "terminal translocation" beneath...
