Leptin-responsive neurons of the hypothalamus constitute a heterogeneous population expressing a vast array of different neuropeptides and neurotransmitters, some of which participate in the regulation of hunger and satiety. Here we report that somatostatin modulates the efficacy of leptin-signalling in the rat hypothalamus. Using a two-pulse paradigm at(More)
Hypothalamic leptinoceptive neurones can be visualized by histochemical demonstration of leptin-induced nuclear translocation of the signalling molecule STAT3. We investigated the relationship of the leptinoceptive neurones to the somatostatin signalling system. With double-labelling immunohistochemistry, we studied the colocalization of leptin-activated(More)
