Neuropeptide Y Cells Regulate Anxiety Behavior, Katelynn Corder

All ETDs from UAB

Dysregulation of the GABAergic system has long been implicated in anxiety disorders. Classic anxiolytic drugs, such as benzodiazepines, increase GABAergic transmission by modulating GABA¬A receptors, relieving anxiety symptoms. However, these treatments are not always effective and are often accompanied by negative side effects. Glutamate decarboxylase (GAD) is the enzyme responsible for producing GABA. Recent studies have shown that when the isoform GAD67 is reduced in specific brain regions or GABAergic subtypes, differential anxiety effects were found. These studies suggest that targeting specific GABAergic cell subtypes may provide a more effective treatment for anxiety disorders. Neuropeptide Y (NPY) is an abundant …
