16. Perturbation of the epithelial barrier by enteric pathogens
Sammanfattning : Gastrointestinal infections in humans have been associated with a number of diseased condition, including stomach ulcers, gastroenteritis, Crohn's disease, and rheumatic arthritis. Such infections often cause altered intestinal permeability through perturbation of the tight junctions that hold epithelial cells together. LÄS MER
17. Studies of Vibrio cholerae toxins (zonula occludens toxin and hemagglutinin/protease) and their effects on epithelial cells
Sammanfattning : Intestinal epithelium is important for absorption of nutrients and for defense against harmful substances in the gut. The permeability and barrier functions of epithelia are mainly controlled by intercellular tight junctions. LÄS MER
18. Characterization of the cellular receptor for coxsackievirus and adenovirus
Sammanfattning : CAR, the cellular receptor for coxsackievirus and adenovirus, was discovered in 1997. CAR is an evolutionary conserved transmembrane protein that belongs to the CTX subfamily within the large immunoglobulin superfamily. At the intracellular tail, CAR has a PDZ domain binding motif suggesting that CAR is part of a larger protein complex. LÄS MER
19. The mucus layer and other barriers to intestinal drug absorption
Sammanfattning : The extraepithelial mucus layer acts as a barrier to the absorption and diffusion of drugs. Three in vitro models have been used for studies of this and other intestinal barriers to drug transport. A drug absorption model based on monolayers of the mucus-producing human intestinal goblet HT29-H cell line was developed. LÄS MER
20. On the role of gut microbiota in intestinal physiology and hepatic metabolism
Sammanfattning : The gut microbiota, a complex and dynamic community of microbes in the mammalian gut, has coevolved with us for ample time providing mutual benefits. However, mechanistic knowledge of these has been limited, but are now becoming increasingly clear. LÄS MER
