The therapeutic potential of galanin in the management of pain – a review article

Neuropeptides represent the most diverse family of neurotransmitters counting numerous members and even more G protein-coupled receptors, all of which are potential targets for drug development. Here, we focus on galanin and its three receptors by describing their possible involvement in pain and regeneration. Although animal experiments indicate that galanin, together with other molecules, may act as an endogenous system protecting against pain and improving nerve growth, these results have so far not been translated into patient treatments.
