Hypothalamic regulatory neuropeptide expression
Hypothalamic regulatory neuropeptide expression. Species, exposure and limitations are retained in each linked claim.

How nutrients influence it
Every nutrient with a recorded effect on this component, credited to the nutrient that acted rather than the chapter that recorded it. Open a nutrient to see the findings and the conditions they were measured under.
Other things that act on it
Enzymes, hormones, genes, and other components with a recorded effect. These are not nutrients, so they do not count toward the arrows above. Each finding names the chapter that recorded it.
How nutrients reach it in more than one step
Chains of two or more recorded steps that end here, grouped by the nutrient they start from. Each step is a separate finding, so a chain is a route a mechanism could take, not proof that it does.

What it does
Every recorded relationship this component is part of, grouped by its role. Plain wording comes first; the technical statement follows.
Where it participates (unsigned role)
Intraperitoneal acetate resulted in appetite suppression and hypothalamic neuronal activation patterning, was associated with activation of acetyl-CoA carboxylase and changes in the expression profiles of regulatory neuropeptides that favour appetite suppression, and regionally increased the labelling of the glutamate-glutamine and GABA neuroglial cycles, suggesting a direct role for acetate in central appetite regulation.
