Lactate and LDHA in pulmonary arterial hypertension

LDHA-lactate signaling in pulmonary arterial hypertension

NIH-funded research University of California at Davis · NIH-11235916

This work looks at how excess lactate made by artery cells may drive thickening of lung blood vessels in people with pulmonary arterial hypertension.

What this research studies

From my perspective as a patient, the researchers are studying cells from the small arteries in the lungs to see how the enzyme LDHA causes extra lactate production and harmful chemical changes inside those cells. They will examine how lactate-driven changes (like altered proteins and DNA modification) make artery muscle and support cells multiply and resist cell death. The team will use cell experiments, molecular analyses, and likely lab models to test whether blocking LDHA or lactate signaling reverses those changes. The goal is to find molecular targets that could be tested later in treatments for PAH.

Who could benefit from this research

Good fit: People diagnosed with pulmonary arterial hypertension, especially those willing to provide tissue or blood samples or to participate in future clinical studies, would be the most relevant candidates.

Not a fit: People with other types of pulmonary hypertension related to left heart disease or lung disease, or those without PAH, are unlikely to benefit directly from this lab-focused project.

Why it matters

Potential benefit: If successful, this could point to new drug targets that slow or reverse artery remodeling in pulmonary arterial hypertension.

How similar studies have performed: Related work in cancer and early PAH research has linked LDHA and lactate to cell growth, but targeting lactate signaling for PAH is still a new and experimental approach.
