CFLAR and idiopathic pulmonary fibrosis: Concomitantly, in a mirror experiment, following miR-34a upregulation with a specific mimic, we show that there is an inverse correlation between the levels of miR-34a and FLIP and that miR-34a increases susceptibility to Jurkat T-cell induced cell death in myofibroblasts from lungs of humans with IPF as well as of miR34aKO mice (Figure 7).
