Brain Controls Blood Cholesterol, Study

A neural circuit in the brain involving the hunger-signaling hormone ghrelin directly controls cholesterol metabolism by the liver.

[La ghréline est une hormone qui stimule l’appétit ]

Ghrelin is a hunger-signaling hormone that inhibits the melanocortin 4 receptor (MC4R) in the hypothalamus and plays a key role in regulating food intake and energy use.

Using lab mice, Tschöp and colleagues found that higher levels of ghrelin caused them to develop higher levels of blood-circulating cholesterol, which they attribute to a reduction in uptake by the liver.
