Identification of MarvelD3 as a tight junction-associated transmembrane protein of the occludin family [PDF]

open access: yesBMC Cell Biology, 2009
Background Tight junctions are an intercellular adhesion complex of epithelial and endothelial cells, and form a paracellular barrier that restricts the diffusion of solutes on the basis of size and charge.

PEAK1 maintains tight junctions in intestinal epithelial cells and resists colitis by inhibiting autophagy-mediated ZO-1 degradation [PDF]

open access: yesNature Communications
Tight junctions are crucial for maintaining intestinal barrier homeostasis, but how organisms modulate these junctions remain unclear. Here, we show a role for PEAK1 at cell-cell contact sites, where it interacts with ZO-1 via a conserved region spanning

Mechanisms of Intestinal Epithelial Barrier Dysfunction by Adherent-Invasive Escherichia coliSummary [PDF]

open access: yesCellular and Molecular Gastroenterology and Hepatology, 2017
Pathobiont expansion, such as that of adherent-invasive Escherichia coli (AIEC), is an emerging factor associated with inflammatory bowel disease. The intestinal epithelial barrier is the first line of defense against these pathogens.

The role of ZEB1 in regulating tight junctions in antrochoanal polyp [PDF]

open access: yesHeliyon
Background: Antrochoanal polyp (ACP) is a benign nasal mass of unknown etiology. Tight junctions (TJs) are essential to the epithelial barrier that protects the body from external damage.

Protective Effects of Baicalin on Peritoneal Tight Junctions in Piglets Challenged with Glaesserella parasuis

open access: yesMolecules, 2021
Glaesserella parasuis (G. parasuis) causes inflammation and damage to piglets. Whether polyserositis caused by G. parasuis is due to tight junctions damage and the protective effect of baicalin on it have not been examined.

Nanoscale segregation of channel and barrier claudins enables paracellular ion flux

open access: yesNature Communications, 2022
Meshworks of claudin polymers control the paracellular transport and barrier properties of epithelial tight junctions. Here, the authors show different claudin nanoscale organization principles, finding that claudin segregation enables barrier formation ...

GAPDH Released from Lactobacillus johnsonii MG Enhances Barrier Function by Upregulating Genes Associated with Tight Junctions

open access: yesMicroorganisms, 2023
Extracellular glyceraldehyde-3-phosphate dehydrogenase (GAPDH) has multiple interactions with various gut epithelial components. For instance, GAPDH in Lactobacillus johnsonii MG cells interacts with junctional adhesion molecule-2 (JAM-2) in Caco-2 cells

Tight Junctions as Targets and Effectors of Mucosal Immune HomeostasisSummary

open access: yesCellular and Molecular Gastroenterology and Hepatology, 2020
Defective epithelial barrier function is present in maladies including epidermal burn injury, environmental lung damage, renal tubular disease, and a range of immune-mediated and infectious intestinal disorders. When the epithelial surface is intact, the

Adherens, tight, and gap junctions in ependymal cells: A systematic review of their contribution to CSF-brain barrier

open access: yesFrontiers in Neurology, 2023
IntroductionThe movement of fluids and solutes across the ependymal barrier, and their changes in physiologic and disease states are poorly understood.
