Shared Reference Notes

  • [1.1] [#Sjögren syndrome
    - pSS patients had gut dysbiosis associated with increased serum levels of proinflammatory cytokines including IL-6, IL-12, IL-17 and TNF-alpha (systemic inflammation) and zonulin (intestinal permeability) that resulted in increased systemic microbial exposure.
  • [1.2] [#Gestational diabetes mellitus (GDM)
    - Elevated expression of serum zonulin, a marker of gut epithelial permeability, during early pregnancy in women with GDM indicates a possible link between gut microbiota and GDM.
  • [1.3] [#Parkinson’s Disease
    - #Alpha-1-antitrypsin and zonulin are markers of intestinal hyperpermeability in PD
  • [1.4] [#Parkinson’s Disease
    - Other possible inflammatory markers of PD are #Calprotectin and zonulin. - The first is a marker of inflammation, while the second is a junction protein, which, if modulated by proinflammatory signals (e.g., LPS), can lead to an increase in intestinal membrane permeability. - both fecal and serum levels of #Calprotectin and zonulin are elevated in patients with PD
  • [1.5
    - The serum zonulin levels of #Covid-19 patients with the mild clinical course were lower than the healthy control group. Moreover, serum zonulin levels were not correlated with ESR, CRP, and other inflammation markers
  • [1.6] [#Depression] [#Lipopolysaccharide
    - Depressed individuals had ↑ circulating IgM and ↑ IgA antibodies against LPS, indicating increased bacterial translocation. - Individuals with depressive and/or anxiety disorders had altered plasma levels of: ↑ LPS, ↑ zonulin, and ↑ fatty acid-binding protein 2, as well as an overrepresentation of LPS biosynthesis genes in the fecal microbiome. - Couples with hostile marital interactions had altered circulating: ↑ LPS binding protein (LBP), and ↑ CRP, and individuals with a history of mood disorders had altered circulating levels: ↑ ratio LBP/sCD14 and ↑ CRP
  • [1.7] [#Bipolar disorder
    - The increment of serum zonulin levels may be related to higher susceptibility for #Depression induced by stimuli. - zonulin and claudin-5 have seen increased in patients with BD.
  • - zonulin and #Claudin-5 have been proposed as biomarkers to detect BBB disruption.
  • - Zonulin modulates intercellular tight junctions and increases intestinal permeability in jejunum and ileum.
  • [1.8
    - Treatment with larazotide acetate, a specific molecular antagonist of zonulin, completely reversed gut permeability
  • [1.9] [#Claudin-1, #Claudin-5
