How brain immune cells influence pulmonary hypertension

Neuroimmune axis contribution to the pathophysiology of pulmonary hypertension

NIH-funded research University of Florida · NIH-11138676

This work looks at whether immune cells in a brain region cause nerve overactivity that makes pulmonary hypertension worse for people with the condition.

What this research studies

Researchers will use laboratory models to see how immune cells called microglia change nerve signals in a brain area that controls the heart and lungs. They will focus on a microglia subtype marked by the molecule TREM2 and use imaging, cell-targeting, and cell-removal techniques to change microglia behavior. The team will measure effects on nerve activity and on signs of pulmonary hypertension to link brain changes to lung blood pressure. These experiments aim to find new targets that could guide future treatments for people with PH.

Who could benefit from this research

Good fit: Adults diagnosed with pulmonary hypertension are the patient group most relevant to this research.

Not a fit: People without pulmonary hypertension or those whose PH is driven primarily by non-neuroimmune factors are unlikely to benefit directly from these findings.

Why it matters

Potential benefit: If successful, this work could point to new treatment targets in the brain that reduce harmful nerve overactivity and improve outcomes for people with pulmonary hypertension.

How similar studies have performed: Prior animal studies link neuroinflammation to cardiovascular problems, but targeting TREM2+ microglia in pulmonary hypertension is a relatively new and largely untested approach.
