Zusammenfassung der Projektergebnisse

This report shows the efficacy of elafin, a naturally occurring elastase inhibitor, in reversing severe experimentally-induced pulmonary hypertension associated with an obliterative vasculopathy, and in causing regression of the neointima in cultured explants of human pulmonary arteries taken from patients with pulmonary arterial hypertension. The mechanism involves elastase inhibition and caveolin-dependent amplification of BMPR2 signaling which together promote regression of occlusive lesions, endothelial restoration and vascular regeneration.
