TITLE=Cholecystokinin-Like Peptide (DSK) in Drosophila, Not Only for Satiety Signaling JOURNAL=Frontiers in Endocrinology VOLUME=5 YEAR=2014 URL=https://www.frontiersin.org/journals/endocrinology/articles/10.3389/fendo.2014.00219 DOI=10.3389/fendo.2014.00219 ISSN=1664-2392 ABSTRACT=

Cholecystokinin (CCK) signaling appears well conserved over evolution. In Drosophila, the CCK-like sulfakinins (DSKs) regulate aspects of gut function, satiety and food ingestion, hyperactivity and aggression, as well as escape-related locomotion and synaptic plasticity during neuromuscular junction development. Activity in the DSK-producing neurons is regulated by octopamine. We discuss mechanisms behind CCK function in satiety, aggression, and locomotion in some detail and highlight similarities to mammalian CCK signaling.
