Background & Aims: Celiac disease is an immune-mediated enteropathy triggered by gliadin, a component of the grain protein gluten. Gliadin induces an MyD88-dependent zonulin release that leads to increased intestinal permeability, a postulated early element in the pathogenesis of celiac disease. We aimed to establish the molecular basis of gliadin interaction with intestinal mucosa leading to

This process activates a cascade of (57) [Summary] Zonulin peptide antagonists and methods of use thereof are disclosed. Peptide antagonists bind to the zonulin closed band receptor but do not physiologically regulate the release of human tight junctions. Interestingly enough, the Immundiagnostik polyclonal antibodies raised against the zonulin synthetic peptide inhibitor GGVLVQPG (AT1001) recognized the same main bands detected by the monoclonal antibodies but with different intensity, being the recombinant zonulin and serum α-chain bands fainter compared with the monoclonal antibody signal, while the serum β-chain and serum zonulin-like Widely Used Commercial ELISA Does Not Detect Precursor of Haptoglobin2, but Recognizes Properdin as a Potential Second Member of the Zonulin Family February 2018 Frontiers in Endocrinology 9:22 HP (Haptoglobin) is a Protein Coding gene.

Twenty healthy, young male volunteers completed a randomized, double-blind crossover study consisting of a 2-week run-in period and two 5-week study periods (11% inulin-enriched or control pasta), with an 8-week Chemokine receptor CXCR3 is the receptor for specific gliadin peptides that cause zonulin release and subsequent increase in intestinal permeability.3 In vitro research with chemokine receptor Zonulin is a protein that reversibly modulates the permeability of tight junction of the small intestine wall. As the serum concentration of “zonulin family peptides” (ZFPs) is considered to be a sensitive and useful marker of intestinal wall permeability, its serum level may affect the volume of ascites fluid and change in gut microbiota.

Therefore, further studies are required to better understand the complex role of barrier function, i.e., intestinal and As the precursor to haptoglobin-2, zonulin belongs to the haptoglobin family of proteins.

Elevated fecal levels of a zonulin family protein (ZFP) have been associated with metabolic syndrome and obesity; conditions that have been linked to increased intestinal permeability ("leaky gut"). Elevated serum levels of the ZFP antigen have been correlated with results from the established lactulose mannitol test.

Zonulin (MW 47,000 Da) is a biomarker of the intestinal barrier integrity of the small intestine. 37,49,65,66 At this time, it is recognized as the only physiological protein known to reversibly regulate intestinal permeability by disassembling intercellular tight junctions. 37,67,68 The secretion of zonulin is mainly derived from the liver but also other tissue, including enterocytes; adipose tissue; the brain, heart, lungs, kidney, and skin; and immune cells. 37,51,69

After binding of gluten peptides to the chemokine receptor CXCR3, zonulin is released and subsequently increases intestinal permeability. This observation has led to a novel treatment option for CD based on the inhibition of zonulin (no. 4 in Figure 3.1). At the same time, gliadin-permeating peptides 111–130 and 151–170 initiate intestinal permeability through a MyD88-dependent release of zonulin (as we have recently confirmed by identifying CXCR3 as the receptor that releases zonulin in a MyD88-dependent manner, see Ref. 92) that enables paracellular translocation of gliadin and its subsequent interaction with macrophages (through 33-mer The Zonulin Family Protein reagent is RUO (Research Use Only) to test human serum or cell culture lab samples.
