Inhibition of TMEM16A represents a novel therapeutic approach to reverse remodelling in PAH.TMEM16A plays a central role in the pathological mechanisms underlying the depolarisation, vasoconstriction and proliferation of PASMCs, contributing to the increased pulmonary vascular resistance in PAH, thus providing a novel target for PAH therapy http://ow.ly/3Rs330o3CUy ER -
