Diesel exhaust particle exposure reduces expression of the epithelial tight junction protein Tricellulin [PDF]

Particle and Fibre Toxicology, 2020
Background While exposure to diesel exhaust particles has been linked to aberrant immune responses in allergic diseases such as asthma, little attention has been paid to their effects on the airway epithelial barrier.

Expression of tricellular tight junction proteins and the paracellular macromolecule barrier are recovered in remission of ulcerative colitis [PDF]

BMC Gastroenterology, 2021
Background Ulcerative colitis (UC) has a relapsing and remitting pattern, wherein the underlying mechanisms of the relapse might involve an enhanced uptake of luminal antigens which stimulate the immune response.

Mechanistic study on Tricellulin regulation of colorectal cancer cell invasion, metastasis and epithelial-mesenchymal transition

结直肠肛门外科
[Objectives] To investigate the related molecular mechanisms by which Tricellulin regulates the invasion, migration and metastasis and epithelial-mesenchymal transition (EMT) progression in colorectal cancer. [Methods] Tissue specimens from 40 colorectal

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

BMC 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.

The Role of Tricellulin in Epithelial Jamming and Unjamming via Segmentation of Tricellular Junctions [PDF]

Advanced Science, 2020
Collective cellular behavior in confluent monolayers supports physiological and pathological processes of epithelial development, regeneration, and carcinogenesis. Here, the attainment of a mature and static tissue configuration or the local reactivation

Tricellulin Is Expressed in Autotypic Tight Junctions of Peripheral Myelinating Schwann Cells [PDF]

Journal of Histochemistry & Cytochemistry, 2010
Autotypic tight junctions are formed by tight junction-like structures in three regions of myelinating Schwann cells, the paranodal loops, Schmidt–Lanterman incisures, and outer/inner mesaxons, and various tight junction molecules, including claudin-19 ...

Redox regulation of cell contacts by tricellulin and occludin: redox-sensitive cysteine sites in tricellulin regulate both tri- and bicellular junctions in tissue barriers as shown in hypoxia and ischemia

Antioxidants & Redox Signaling, 2015
Tight junctions (TJs) seal paracellular clefts in epithelia/endothelia and form tissue barriers for proper organ function. TJ-associated marvel proteins (TAMPs: tricellulin, occludin, marvelD3) are thought to be regulatory relevant.

ReFerm® a Fermented Oat Gruel Composition, Improves Colonic Barrier Function and Modulates Tricellulin Expression in Patients With Irritable Bowel Syndrome. [PDF]

Neurogastroenterol Motil
Patients with irritable bowel syndrome (IBS) have been shown to have impaired gut barrier function, which may contribute to gut symptoms by allowing substances to pass more easily through the intestinal lining. In this study, the fermented oat‐based preparation ReFerm® reduced gut permeability and strengthened the gut barrier in colonic biopsies from ...

The Intestinal Barrier: A Multilayered Gatekeeper Against Systemic Disease. [PDF]

Int J Microbiol
The intestine performs two distinct yet seemingly contradictory functions: the digestion and absorption of nutrients, and the defense against harmful substances and pathogens. The intestinal barrier is a multilayered system maintained by four key components: the physical, chemical, microbiological, and immunological barriers.
