Concentrations of PGE2 molecule in the brain linked to both weight loss and weight gain

A team of medical researchers at Memorial University, in Canada, has found evidence showing that concentrations of the PGE2 molecule in the brain can lead to both weight loss and weight gain depending on the amount. In their study, reported in Proceedings of the National Academy of Sciences, the group tested the impact of changes in concentrations of the PGE2 molecule in the hypothalamus in rats and mice.
