The discovery of a novel molecular switch that powerfully modulates nerve cell activity offers the potential for new mood disorder and epilepsy treatments, University of California, Irvine researchers report.The researchers looked at the role of the natural substance cholecystokinin (CCK) in modulating communication between cells in the brain. CCK, originally isolated from the digestive tract, is one of the most abundant small proteins, or peptides, in the brain, and it is linked to psychiatric disorders such as anxiety, depression, and schizophrenia.
