Scientists found a brain-immune-heart pathway that worsens heart attacks in mice, suggesting new treatment possibilities.
Scientists at UC San Diego have identified a brain-immune-heart pathway that worsens heart attack damage in mice, showing that TRPV1-expressing vagus nerve neurons trigger inflammation through a circuit involving the hypothalamus.
Disrupting any part of this neural loop—by silencing neurons, targeting the brain, or blocking immune responses—significantly improved heart function, reduced tissue damage, and stabilized electrical activity.
The findings, published in Cell, reveal the brain’s active role in amplifying heart injury and suggest that existing vagus nerve stimulators, already used for autoimmune diseases, could be repurposed for heart attack therapy.
While human applications are years away, the study marks a shift toward understanding the nervous and immune systems as central to cardiovascular health.
