Treprostinil inhibits the adhesion and differentiation of fibrocytes via the cyclic adenosine monophosphate-dependent and Ras-proximate protein-dependent inactivation of extracellular regulated kinase.

Abstract excerpt

Fibrocytes comprise a recently described cell type of blood-derived, fibroblast-like cells that are recruited from the circulation to sites of wound repair, vascular remodeling, or fibrotic tissue remodeling. We recently showed that the stable prostacyclin analogue treprostinil, a clinically approved drug for pulmonary arterial hypertension (PAH), significantly reduced the recruitment of fibrocytes to sites of...
