Modulation of endothelin receptors in the failing right ventricle of the heart and vasculature of the lung in human pulmonary arterial hypertension.

Kuc RE, Carlebur M, Maguire JJ, Yang P, Long L, Toshner M, Morrell NW, Davenport AP - Life Sci. (2014)

Bottom Line: In human PAH lungs, ETA receptors were significantly increased in the medial layer of small pulmonary arteries with no change detectable in MCT rat vessels.The increase in ETA receptors in arteries provides a mechanism for the beneficial vasodilator actions of ET antagonists.The increase in the ratio of ETA in RV also implicates changes to ET signalling although it is unclear if ET antagonism is beneficial but the results emphasise the unexploited potential for therapies that target the RV, to improve survival in patients with PAH.
