Pulmonary arterial hypertension-associated cerebellar impairment extends evidence linking cardiometabolic and neurodegenerative diseases.

Impaired lysosomal lipid handling in endothelial cells and microglia is linked to a neurological disorder associated with pulmonary arterial hypertension (PAH), extending cardiometabolic–neurodegenerative evidence.

• Why it matters: Cognitive impairment risk is elevated in metabolic and cardiovascular diseases, yet the mechanisms connecting cardiopulmonary pathology to specific brain disorders are unclear.
• What they did: Okawa, Shi, and colleagues combined PAH cohort clinical investigation with a mouse model and microglial cell culture to test microglial involvement and lysosomal lipid handling.
• The result: The integrated findings provide indirect evidence that lysosomal lipid handling defects in endothelial cells and microglia are associated with the PAH-linked neurological disorder, suggesting a route to study disease predisposition to neurodegeneration.
