Occludin regulation of blood–brain barrier and potential therapeutic target in ischemic stroke

Brain Circulation, 2020
Occludin is a key structural component of the blood–brain barrier (BBB) that has recently become an important focus of research in BBB damages. Many studies have demonstrated that occludin could regulate the integrity and permeability of the BBB.

Epididymal epithelial degeneration and lipid metabolism impairment account for male infertility in occludin knockout mice

Frontiers in Endocrinology, 2022
Occludin (OCLN) is a tight junction protein and Ocln deletion mutation causes male infertility in mice. However, the role of OCLN in male reproductive system remains unknown.

Intestinal Alkaline Phosphatase Prevents Sulfate Reducing Bacteria-Induced Increased Tight Junction Permeability by Inhibiting Snail Pathway

Frontiers in Cellular and Infection Microbiology, 2022
Tight junctions (TJs) are essential components of intestinal barrier integrity and protect the epithelium against passive paracellular flux and microbial translocation.

Exposure of human intestinal epithelial cells and primary human hepatocytes to trypsin-like serine protease inhibitors with potential antiviral effect

Journal of Enzyme Inhibition and Medicinal Chemistry, 2021
Human intestinal epithelial cell line-6 (HIEC-6) cells and primary human hepatocytes (PHHs) were treated with 3-amidinophenylalanine-derived inhibitors of trypsin-like serine proteases for 24 hours.

Effects of high incubation temperature on tight junction proteins in the yolk sac and small intestine of embryonic broilers

Poultry Science, 2023
: During the transition from incubation to hatch, the chicks shift from obtaining nutrients from the yolk sac to the intestine. The yolk sac tissue (YST) and small intestine serve as biological barriers between the yolk or gut contents and the blood ...
