Targeting Macrophage Crosstalk to PASMC by Blunting Inflammatory Phenotype Via SerpinB1 Protects Against Hypoxia-Induced Pulmonary Hypertension

Hypoxia exposure directly amplifies the pro-proliferative crosstalk of macrophages to PASMCs via downregulating SerpinB1 to induce caspase-1 activation and inflammatory phenotype. Targeting macrophage SerpinB1 may hold promise for treating pulmonary hypertension.
