Small intestinal permeability

Current Opinion in Gastroenterology, 2000
The noninvasive assessment of small intestinal permeability in humans is now within the capability of any routine biochemistry laboratory. There remain however, many pitfalls for the unwary when performing these tests. Importantly, it has now been shown that normal intestinal permeability relates to geographical location rather than race.

Intestinal permeability and contractility in murine colitis [PDF]

Mediators of Inflammation, 1998
We developed an in vitro organ bath method to measure permeability and contractility simultaneously in murine intestinal segments. To investigate whether permeability and contractility are correlated and influenced by mucosal damage owing to inflammation,

Modulation of Intestinal Epithelial Permeability via Protease-Activated Receptor-2-Induced Autophagy

Cells, 2022
Protease-activated receptor 2 (PAR2) alleviates intestinal inflammation by upregulating autophagy. PAR2 also modulates tight junctions through β-arrestin signaling.

Intestinal permeability in kwashiorkor [PDF]

Archives of Disease in Childhood, 1997
Intestinal permeability can be assessed non-invasively using the lactulose-rhamnose (L-R) test, which is a reliable measure of small intestinal integrity.To determine risk factors for abnormal intestinal permeability in kwashiorkor, and to measure changes in L-R ratios with inpatient rehabilitation.A case-control study of 149 kwashiorkor cases and 45 ...

Psychosocial stress-induced intestinal permeability in healthy humans: What is the evidence?

Neurobiology of Stress, 2023
An impaired intestinal barrier function can be detrimental to the host as it may allow the translocation of luminal antigens and toxins into the subepithelial tissue and bloodstream. In turn, this may cause local and systemic immune responses and lead to
