Stress shows up in the body as well as the mind. It affects blood pressure, appetite, body weight and heart health.

corticotropin-releasing hormone

Grants
3 known grants, through Feb 2031

What they work on

  1. Determine how HPA stress-axis activity reduces weight-loss quality, including muscle loss, during treatment with GLP-1 receptor agonists such as semaglutide, using a CRF-neutralizing antibody (Anti-CRF) in mice.
  2. Test whether suppressing HPA axis activity with Anti-CRF blunts overeating and weight regain after GLP-1 receptor agonist treatment stops.
  3. Use intravital imaging to test whether chronic social defeat stress dulls responses of oxytocin-receptor nodose ganglion neurons to stretch of the blood vessels and gut.
  4. Delete the stretch sensor Piezo2 from oxytocin-receptor nodose neurons, and chemogenetically stimulate these neurons during social stress, to test effects on hypertension, overeating and anxiety-like behavior.
  5. Use Cre-LoxP mice and in vivo optogenetics to test whether exciting or inhibiting neurons expressing angiotensin receptors AT1R, AT2R or MasR reduces or worsens stress responses.
  6. Determine how a stress-induced disease model changes AT1R, AT2R and MasR neurons, and test whether optogenetic, genetic or pharmacological manipulation of them reverses stress-induced pathophysiology.

More about the research

Research across the lab's projects examines how the brain's stress systems and the nerves that sense the heart and gut shape cardiovascular and metabolic disease. The projects use genetically engineered mice and tools that switch specific neurons on or off. They ask how stress circuits drive high blood pressure and weight gain, and whether calming those circuits can protect health or improve weight-loss drugs.

Why it matters

Obesity, high blood pressure and cardiovascular disease, the leading U.S. cause of death, are all worsened by stress. This work could improve GLP-1 drugs like semaglutide by preserving muscle and preventing weight regain. It could also identify nerve and brain targets for treating stress-linked hypertension, overeating and anxiety, including in socially disadvantaged populations.
