A two-dimensional iPSC-derived small intestinal epithelium model from a celiac disease patient shows cytokine-induced upregulation of IRF1, ICAM1, and IDO1.
- Why it matters: Celiac disease involves wheat-triggered immune-mediated enteropathy with IFNg upregulation, but planar iPSC epithelial models enabling direct two-sided assessment were missing.
- What they did: iPSCs from a celiac disease patient and a control patient were differentiated on Transwell inserts into small intestinal epithelium without an organoid phase, then assessed by immunofluorescence, transcriptomics, and LDH cytotoxicity.
- The result: Both celiac and healthy iPSC-SIECs increased IRF1, ICAM1, and IDO1 and other cytokine-responsive genes after cytokine stimulation, supporting use of the celiac-derived 2D platform for inflammation-associated enteropathies like celiac disease.
