New Findings from Hannover Medical School in Right Ventricular Provides New Insights (Novel Tryptophan Hydroxylase Inhibitor Tpt-001 Reverses Pah, Vascular Remodeling, and Proliferative-proinflammatory Gene Expression).

Researchers from Hannover Medical School in Germany have developed a new inhibitor called TPT-001 that targets the serotonin pathway, which has been proposed as a potential treatment for pulmonary arterial hypertension (PAH). In a study using a rat model of severe PAH, the researchers found that oral treatment with TPT-001 significantly reduced right ventricular dysfunction, lowered pulmonary arterial pressures, and reversed pulmonary vascular remodeling. The study suggests that inhibiting the serotonin pathway with TPT-001 has the potential to attenuate or even reverse severe PAH and associated right ventricular dysfunction.
