<unk>  has been shown to interact with the<unk>  A receptor located mainly on pancreatic acinar cells and<unk>  B receptor mostly in the brain and stomach.<unk> B receptor also binds gastrin, a gastrointestinal hormone involved in stimulating gastric acid release and growth of the gastric mucosa.<unk>  has also been shown to interact with calcineurin in the pancreas. Calcineurin will go on to activate the transcription factors NFAT 1–3, which will stimulate hypertrophy and growth of the pancreas.<unk>  can be stimulated by a diet high in protein, or by protease inhibitors.<unk>  has been shown to interact with orexin neurons, which control appetite and wakefulness (sleep).<unk>  can have indirect effects on sleep regulation.<unk>  in the body cannot cross the blood-brain barrier, but certain parts of the hypothalamus and brainstem are not protected by the barrier.
