Es wird angenommen, dass Entzündungssignale entscheidend für die Pathogenese (Entstehung und Entwicklung) der PAH sind; der zugrunde liegende Mechanismus...Inflammatory signals are thought to be crucial for the pathogenesis of PAH; however, the underlying mechanism is still largely unknown. In this study, we demonstrate that AHR makes a causal contribution to the pathogenesis of PAH, activating a focal inflammatory response in the lungs and promoting infiltration of immune cells from the bone marrow. Furthermore, we found that PAH patients with higher AHR agonistic activity in sera are more susceptible to severe clinical events than those with lower activity. Because conventional therapy for pulmonary hypertension targeting pulmonary artery vasodilation has limited efficacy against severe PAH, the AHR-signaling pathway represents a promising therapeutic target for PAH. In addition, AHR agonistic activity in serum represents a biomarker for PAH. Raw data of RNA-seq and ChIP-seq analysis of SuHx rats have been deposited in the National Center for Biotechnology Information Gene Expression Omnibus (GEO) database, <https://www.ncbi.nlm.nih.gov/geo/> (accession no. [GSE162245][1]). All other study data are included in the article and supporting information. [1]: http://www.ncbi.nlm.nih.gov/geo/query/acc.cgi?acc=GSE162245
