Bronchial epithelial cells are rendered insensitive to glucocorticoid transactivation by transforming growth factor-β1

Abstract excerpt

BACKGROUND: We have previously shown that transforming growth factor-beta (TGF-beta) impairs glucocorticoid (GC) function in pulmonary epithelial cell-lines. However, the signalling cascade leading to this impairment is unknown. In the present study, we provide the first evidence that TGF-beta impairs GC action in differentiated primary air-liquid interface (ALI) human bronchial epithelial cells (HBECs). Using...
