The background to this themed issue on neuropeptides.

UNLABELLED: A meeting of the British Pharmacological Society in association with the European Neuropeptide Club and Americal Summer Neuropeptide Conference in June 2012 led to this themed issue on neuropetides. A wide range of neuropeptides are discussed, in various physiological and pathophysiological conditions, with respect to their upstream and downstream pathways. It is clear, at this point in time, that targeting neuropeptides has therapeutic potential in pathologies ranging from migraine to obesity. It is also clear from the reviews in this issue of the British Journal of Pharmacology that there is still so much to learn.
