Tumor necrosis factor alpha increases epithelial barrier permeability by disrupting tight junctions in Caco-2 cells.
The objectives of this study were to determine the effect of tumor necrosis factor alpha (TNF-alpha) on intestinal epithelial cell permeability and the expression of tight junction proteins. Caco-2 cells were plated onto Transwell microporous filters and treated with TNF-alpha (10 or 100 ng/mL) for 0, 4, 8, 16, or 24 h. The transepithelial electrical resistance and the mucosal-to-serosal flux r...
متن کاملDengue virus neither directly mediates hyperpermeability nor enhances tumor necrosis factor-α-induced permeability in vitro.
The mechanisms of endothelial barrier dysfunction in dengue disease remain poorly understood. Endothelial cell (EC) death due to virus infection or in combination with an infection-induced cytokine storm is deemed as one of the major causes of plasma leakage. Using an in vitro model of human endothelia and several dengue virus (DENV) strains (including a clinical isolate), the direct consequenc...
متن کاملL-Glutamine ameliorates acetaldehyde-induced increase in paracellular permeability in Caco-2 cell monolayer.
Role of L-glutamine in the protection of intestinal epithelium from acetaldehyde-induced disruption of barrier function was evaluated in Caco-2 cell monolayer. L-Glutamine reduced the acetaldehyde-induced decrease in transepithelilal electrical resistance and increase in permeability to inulin and lipopolysaccharide in a time- and dose-dependent manner; d-glutamine, L-aspargine, L-arginine, L-l...
متن کاملVitamin D increases tight-junction conductance and paracellular Ca2+ transport in Caco-2 cell cultures.
We investigated the effects of 1α,25-dihydroxyvitamin D3[1,25(OH)2D3] on paracellular intestinal Ca2+absorption by determination of transepithelial electric resistance (TEER), as a measure of tight-junction ion permeability and bidirectional transepithelial45Ca2+fluxes in confluent Caco-2 cell cultures. The rise of TEER to steady-state levels of ∼2,000 Ω ⋅ cm2 was significantly attenuated by 1,...
