AI Article Synopsis

Article Abstract

Pulmonary arterial hypertension (PAH) is a severe condition characterised by remodelling of precapillary pulmonary arteries sometimes associated with mutations in the bone morphogenetic protein receptor type 2 (BMPR2) gene. Even in the absence of BMPR2 mutations, increased transforming growth factor (TGF)β receptor signalling and decreased BMPRII signalling have been shown to contribute to PAH pathogenesis. In this Keynote, we review the potential mechanisms by which the imbalance of BMP/TGFβ signalling contributes to endothelial dysfunction, vascular remodelling, inflammation and disordered angiogenesis in PAH. Additionally, we highlight how currently used drugs can influence BMP/TGFβ signalling. Finally, we browse the newly developed therapeutic approaches targeting BMPRII and TGFβ signalling pathways by focusing on preclinical studies and clinical trials and put them into perspectives.
