Sammanfattning : Networks of epithelial tubes, such as the vertebrate lung, kidney and vascular system, enable transport of gases and nutrients to all tissues in the body. These tubes are built up by a single layer of polarized epithelial cells, with the apical membrane facing the lumen. LÄS MER

Sammanfattning : Extravasation of polymorphonuclear leukocytes (PMN) and associated plasma exsudation are key events in the inflammatory process. The mechanism by which activated PMN may induce increased vascular permeability for macromolecules is not fully understood but crucially dependent on an intact leukocytic beta2 integrin (CD11/CD18) adhesion receptor function.

Sammanfattning : The epithelial barrier facing the external environment in the gastrointestinal (GI) tract is comprised of several components, including the tight junction (TJ) structures observed for the first time in 1963. TJ structures, which are multiprotein complexes composed of transmembrane proteins and a diverse spectrum of intracellular components, create a primary barrier to diffusion of ions, solutes, and water and they concomitantly prevent permeation of pro-inflammatory factors, such as pathogens, toxins, and antigens.
