To identify downstream mediators of TGF-β1, epigenetic factors, and metabolic pathways that can be selectively targeted to treat idiopathic pulmonary fibrosis without interfering with tumor-suppressive or immune-modulating functions.
Narrative review synthesizing molecular and translational literature on aging biology and fibrogenesis in idiopathic pulmonary fibrosis.
Evaluation of signaling cascades downstream of TGF-β1 receptors, global epigenetic regulatory mechanisms, and aging-associated metabolic pathways.
Direct upstream inhibition of canonical TGF-β1 receptors presents significant safety hurdles due to its essential homeostatic, tumor-suppressor, and immune-modulatory functions.
Targeting selective mediators downstream of TGF-β1 decouples fibrogenic responses from critical tumor- and immune-suppressive actions, offering safer therapeutic opportunities.
Modulating epigenetic modifications and aging-related metabolic dysregulation yields viable complementary strategies to attenuate progressive lung fibrosis.
