Action against Disease ModelPYY3-36Pharmacological and genetic approaches have revealed that the Y2-receptor mediates the anorectic effects of PYY3-36 whilst mechanistic studies in rodents identified the hypothalamus, vagus and brainstem regions as potential sites of action. More recently, using functional brain imaging techniques in h uMans, PYY3-36 was found to modulate neuronal activity within hypothalamic and brainstem, and brain regions involved in reward processing[7]
The Effect of Target Knockout, Knockdown or Genetic VariationsThe Y1 receptor antagonist BIBO3304 blocked responses to the Y1 agonist at the lower doses, but only partially inhibited at the higher doses tested in Y2+/+ . In Y2+/+ receptor mice, the responses to the Y2 agonist were abolished at the lower doses and partially reduced at the highest dose tested, while those to the Y1 agonist were similar in both Y2+/+ and Y2-/-receptor mice.[8]
