Abstrakt: Proliferation of pulmonary artery smooth muscle cells (PASMCs) leads to adverse vascular remodeling and contributes to pulmonary arterial hypertension, a condition associated with a 15 annual mortality despite treatment. We previously showed that swelling-activated Cl−currents (ICl,swell) are upregulated in PASMC proliferation and that nonspecific Cl−current blockers inhibit proliferation. However, the specific role of ICl,swellin PASMC proliferation and its molecular underpinning remain unknown.
