Mast cells-derived MiR-223 destroys intestinal barrier function by inhibition of CLDN8 expression in intestinal epithelial cells

Biol. Res; 53 (), 2020
BACKGROUND: Mast cells (MCs) have been found to play a critical role during development of inflammatory bowel disease (IBD) that characterized by dysregulation of inflammation and impaired intestinal barrier function. However, the function of MCs in IBD remains to be fully elucidated. RESULTS: In our stu...

Hypoxia-induced hyperpermeability of rat glomerular endothelial cells involves HIF-2α mediated changes in the expression of occludin and ZO-1

Braz. j. med. biol. res; 51 (7), 2018
This study aimed to investigate the role of hypoxia-inducible factor-2α (HIF-2α) in the expression of tight junction proteins and permeability alterations in rat glomerular endothelial cells (rGENCs) under hypoxia conditions. The expression level of HIF-2α and tight junction proteins (occl...

Claudin-3 and occludin content in the glands of colonic mucosa devoid from fecal stream submitted to topical intervention with oil extract of Curcuma longa

Acta cir. bras; 32 (1), 2017
Abstract Purpose: To evaluate the inflammatory intensity and measure the tissue content of the proteins claudin-3 and occludin in the colonic mucosa without fecal stream submit to intervention with curcumin. Methods: Thirty-six rats were submitted to a proximal colostomy and a distal mucous fistula and...

Citoquinas y patogénesis del edema macular diabético

Diabetic macular edema (DME) is the leading cause of visual loss in diabetic patients and is characterized by accumulation of extracellular fluid in the retina. The most important mechanism involved is breakdown of the blood-retinal barrier (BRB), which is likely to be due to changes of tight junction pr...
