The arachidonic acid metabolite 11β-ProstaglandinF2α controls intestinal epithelial healing: deficiency in patients with Crohn’s disease
Open accessAbstract
In healthy gut enteric glial cells (EGC) are essential to intestinal epithelial barrier (IEB) functions. In Crohn’s Disease (CD), both EGC phenotype and IEB functions are altered, but putative involvement of EGC in CD pathogenesis remains unknown and study of human EGC are lacking. EGC isolated from CD and control patients showed similar expression of glial markers and EGC-derived soluble factors (IL6, TGF-β, proEGF, GSH) but CD EGC failed to increase IEB resistance and healing. Lipid profiling showed that CD EGC produced decreased amounts of 15-HETE, 18-HEPE, 15dPGJ 2 and 11βPGF 2 α as compared to healthy EGC. They also had reduced expression of the L-PGDS and AKR1C3 enzymes. Produced by healthy EGC, the 11βPGF 2 activated PPARγ receptor of intestinal epithelial cells to induce cell spreading and IEB wound repair. In addition to this novel healing mechanism our data show that CD EGC presented impaired ability to promote IEB functions through defect in L-PGDS-AKR1C3-11βPGF 2 α dependent pathway.

11-β-PGF2α is the principal immediate metabolic product of both PGD2 and PGE2.
“11-β-PGF 2α is the principal immediate metabolic product of both PGD 2 and PGE 2 [72][73][74].”
From Diagnosis of mast cell activation syndrome: a global "consensus-2" (2021) · cites this paper as [73]
The Discussion (page not provided) calls 11βPGF2α the primary plasma metabolite of PGD2 and states that AKR1C3 converts PGD2 to 11βPGF2α. It does not identify 11βPGF2α as a metabolite of PGE2; its discussion of PGE2 concerns glial production and neuronal responses. (LLM, conf=0.89)

About these checks
Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.
Statistics and arithmetic are recomputed, not judged.
Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
