acts on a molecular structure on brain cells called the growth hormone secret receptor or GHSR for short.
⑤When Ghrelin was put into this area of the rats' brains,
they ate as hungrily as they did after being kept hungry overnight,
the researchers said.
Ghrelin is produced in the gut (肠道) and causes the brain to promote eating.
Several hormones are known to be involved in eating and appetite,
and studies have shown that influencing them can affect weight gain in rats and mice.
Influencing human eating behavior has proven far more difficult, however.
Horvath said it might be possible to design a drag that interferes with GHSR and thus help people with eating disorders.
