Signal Transduction during Metabolic and Inflammatory Reprogramming in Pulmonary Vascular Remodeling. Int J Mol Sci. 2022;23(5):2410. Published 2022 Feb 22. doi:10.3390/ijms23052410https://hdl.handle.net/1805/33184Pulmonary arterial hypertension (PAH) is a progressive disease characterized by (mal)adaptive remodeling of the pulmonary vasculature, which is associated with inflammation, fibrosis, thrombosis, and neovascularization. Vascular remodeling in PAH is associated with cellular metabolic and inflammatory reprogramming that induce profound endothelial and smooth muscle cell phenotypic changes. Multiple signaling pathways and regulatory loops act on metabolic and inflammatory mediators which influence cellular behavior and trigger pulmonary vascular remodeling in vivo. This review discusses the role of bioenergetic and inflammatory impairments in PAH development.en-USAttribution 4.0 InternationalPulmonary arterial hypertensionVascular remodelingSignaling pathwaysMetabolismInflammationArticle
