I see some problems here ''"Peptide YY acts in two different ways through targets in the hypothalamic arcuate nucleus.

NPY is an orexigenic peptide that acts via specific receptors, named Y1...Y5. The Y2 receptor is an inhibitory autoreceptor, i.e. it is expressed by the NPY/AcRP cells and mediates direct negative feedback. PYY is an agonist at the Y2 receptor, so PYY directly inhibits the NPY/AgRP cells. Because NPY cells inhibit the POMC cells, PYY indirectly stimulates the POMC cells to cause an increase in a-MSH release. AMPK is a widely expressed enzyme associated with cellular metabolism - as an "energy sensing" pathway.

Hi Gianna, good work with the references, it would have been even better with a small summary for each article.
Lisa, I moved the references you added into the Bibliography page.
