Effects of Polymorphonuclear Leukocyte Transmigration
We describe a model to study the effects of polymorphonuclear leukocyte (PMN) transmigration on the intestinal epithelial barrier. Human PMN were induced to transmigrate across high resistance monolayers of a cultured human intestinal epithelial cell line (T84 cells) by chemotactic gradients produced by formyl methionyl leucyl phenylalanine (FMLP). With maximal transmigration monolayer resistan...
متن کاملEndothelial adapter proteins in leukocyte transmigration.
Leukocyte transendothelial migration (TEM) requires endothelial signalling. This signalling is initiated by clustering of cell-surface adhesion molecules and transmitted into the endothelium by a group of associated or co-clustered adapter proteins. These adapter proteins, such as cortactin and filamin, connect the adhesion molecules to the actin cytoskeleton as well as to signalling enzymes an...
متن کاملIII. Leukocyte adhesion and transmigration in the liver vasculature.
Leukocytes, i.e., neutrophils, monocytes, and lymphocytes, can accumulate in the hepatic vasculature and contribute to the pathophysiology of various liver diseases. Recently, significant progress has been made in the understanding of the basic mechanisms of neutrophil infiltration and cytotoxicity in the liver. However, there are a substantial number of unresolved issues. This article describe...
متن کاملAge-related intimal stiffening enhances endothelial permeability and leukocyte transmigration.
Age is the most significant risk factor for atherosclerosis; however, the link between age and atherosclerosis is poorly understood. During both aging and atherosclerosis progression, the blood vessel wall stiffens owing to alterations in the extracellular matrix. Using in vitro and ex vivo models of vessel wall stiffness and aging, we show that stiffening of extracellular matrix within the int...
متن کاملEndothelial signaling in paracellular and transcellular leukocyte transmigration.
As the primary physical barrier between blood and tissue compartments within the body, blood vessel endothelial cells and integrity of the cell junctions connecting them must be carefully regulated to support leukocyte transendothelial migration only when necessary. Leukocytes utilize two independent routes across the endothelium: the paracellular route involves migration in-between adjacent en...
