Inflammatory intestinal lesions are often hypoxic, which results in the stabilization and activation of hypoxia-inducible-factors (HIF). Here authors show that in a mouse model of colitis, HIF-2α is specifically stabilized in CD4+ type 1T helper (TH1) cells, leading to the upregulation of miR-29a expression and suppression of TH1 cell function, which pathway is potentially targetable for therapeutic purposes.
