Clonal hematopoiesis with JAK2V617F promotes pulmonary hypertension with ALK1 upregulation in lung neutrophils
Abstract
Pulmonary hypertension is characterized by increased pulmonary arterial pressure, driven in part by inflammatory infiltrates. Here, the authors show that in mice, transgenic expression of mutant JAK2 leads to clonal hematopoiesis and lung accumulation of elastase- and cytokine-expressing neutrophils, and that the phenotype can be reversed by ALK1 inhibition.
