Increased levels of kynurenine catabolites together with tryptophan depletion in the local microenvironment result in metabolic stress on CD4 T cells, leading to impaired T-cell metabolism, impaired antigen-specific response, cell cycle arrest and apoptosis of Th1 cells, inhibition of Th17 cell differentiation, and promotion of Th2 cell polarization [320, 323325]

Additionally, the loss of epithelial-derived niche factors (e.g., WNT ligands, BMPs) destabilizes the epithelial-mesenchymal balance, promoting fibroblast activation and extracellular matrix (ECM) deposition (81)
