Story summary

A groundbreaking study from the University of Pittsburgh reveals a troubling connection between dysfunctional lysosomes and higher mortality rates in pulmonary arterial hypertension. Led by Stephen Chan, researchers discovered that oxysterols serve as inflammatory markers tied to disease severity. A genetic variant, the C allele, diminishes NCOA7 protein levels, impairing lysosomal function and fueling inflammation, opening doors for new treatment strategies.
