Kir2.1 Inhibition Suppresses PASMC Proliferation in PH Model
2026-05-20
The reference study demonstrates that Kir2.1 potassium channels directly regulate pulmonary artery smooth muscle cell (PASMC) proliferation and migration, key processes in pulmonary vascular remodeling during pulmonary hypertension (PH). Using both in vivo and in vitro models, the authors show that selective Kir2.1 inhibition—particularly with ML133—attenuates these pathological responses by suppressing the TGF-β1/SMAD2/3 signaling pathway.
