Polychlorinated biphenyls disrupt intestinal integrity via NADPH oxidase - induced alterations
of tight junction protein expression.
These increases were accompanied by disruption of tight junctions and a decrease in expression
of the tight junction protein occludin.
MMP - 3 was found to contribute to the degradation
of tight junction proteins that are responsible for maintaining the integrity of the BSCB barrier.
Exposure of germ - free adult mice to a pathogen - free gut microbiota decreased BBB permeability and up - regulated the expression
of tight junction proteins.
And, quercetin, which supports the creation
of tight junction proteins, can help «seal» the gut and ease inflammatory bowel disease and ulcerative colitis.

(A) Characteristic staining
of the ZO - 1
tight junction protein in untreated controls.
IL - 1β was reducing the production
of tight -
junction proteins, which are crucial to making the intestinal barrier impermeable to pathogens.
However, the team was able to show that so - called
tight junction proteins, which are known to be important for the blood - brain barrier permeability, did undergo structural changes and had altered levels
of expression in the absence
of bacteria.
Our work provides evidence that Cd14 is pivotal for regulating
tight junction proteins by reducing the expression
of pro-inflammatory cytokine.
By interacting with the actin cytoskeleton, underneath the cell outer membrane, and other structural
proteins of the
tight junctions, Alix ensures the formation
of the actomyosin -
tight junction complex at a specific position between adjacent cells.
Correct
tight junctions between cells labeled in yellow due to the presence
of the
protein PARD3.
Autoimmune diseases lead to increased levels
of pro-inflammatory cytokines and nitric oxide, which can destroy intestinal
tight junction proteins and contribute to leaky gut syndrome.
A
protein called zonulin is responsible for induction
of tolerance and orchestration
of immune responses by modulating intercellular
tight junctions in the gastrointestinal epithelium in a rapid, reversible, and reproducible fashion (Fasano, 2011).
Tight junctions, regulated by a molecule called zonulin, as well as by conformational changes in the
proteins occludin and claudin, are dynamic intercellular structures that modulate the trafficking or passage
of macromolecules from the intestinal lumen to the submucosa and into systemic circulation (Fasano, 2012).
Another study published in 2006 in the Scandinavian Journal
of Gastroenterology Journal found that gliadin which is a
protein present in wheat and gluten increases * zonulin; when zonulin increases *, it makes the
tight junctions more permeable preventing it from working properly leading to a leaky gut and a leaky brain.
These
tight junctions consist
of proteins including claudins, occludins, and E-cadherin, among others.
In the small intestine, gluten triggers the release
of zonulin, a
protein that regulates the
tight junctions between epithelial cells and therefore intestinal, but also blood - brain barrier function.
RESTORE has also been shown in lab testing to increase and strengthen the
tight junction proteins in the gut lining, our frontline
of defense against environmental factors in our food, water, and even air, thereby impacting the immune system, as much
of the body's immune system is in the gut lining.
The
tight junctions are made up
of membrane spanning
proteins, anchoring
proteins and drawstrings that work together to uphold the integrity
of the
tight junction.
You can think
of the
proteins that make up the
tight junctions as structural
proteins.
It is this combination
of membrane spanning
proteins and anchoring
proteins and drawstrings that create the
tight junction.
There are several types
of proteins that create the
tight junction.
Disruption
of brain barrier results first in the release
of BBB
proteins and then in the formation
of IgG, IgM or IgA antibodies against
tight junctions and BBB
proteins.
