To establish the clinical relevance of STING expression to PH in a cell-specific manner, we reanalyzed a previously published single-cell RNA-Seq (scRNA-Seq) dataset from lungs of patients with PAH (compared with control donors without disease; n = 3/group) (25) for differential STING expression across common pulmonary cell types. Here, STING1 is linked to pulmonary arterial hypertension.
