Neuropeptides and anxiety: focus on cholecystokinin.
Cholecystokinin (CCK), a gastrin-like neuropeptide, exists in the central nervous system in several forms. The octapeptide (CCK-8) occurs in predominantly sulfated form (CCK-8S), and the tetrapeptide (CCK-4) occurs in smaller but significant quantities. This review highlights recent developments in preclinical and clinical research into the potential role for CCK in mediating anxiety states. Re...
متن کاملAmphetamine-induced anxiety-related behavior in animal models.
The purpose of this study was to examine the anxiety-related effects of acute and repeated amphetamine administration using the elevated plus maze (EPM) and light/dark box tests in mice. D-amphetamine (2 mg/kg ip, 30 min after injection) had a significant anxiogenic effect only in the EPM test, as shown by specific decreases in the percentage of time spent in the open arms as well as in the per...
متن کاملA Hypomorphic Vasopressin Allele Prevents Anxiety-Related Behavior
BACKGROUND To investigate neurobiological correlates of trait anxiety, CD1 mice were selectively bred for extremes in anxiety-related behavior, with high (HAB) and low (LAB) anxiety-related behavior mice additionally differing in behavioral tests reflecting depression-like behavior. METHODOLOGY/ PRINCIPAL FINDINGS In this study, microarray analysis, in situ hybridization, quantitative real-ti...
متن کاملA role for LYNX2 in anxiety-related behavior.
Anxiety disorders are the most prevalent mental disorders in developed societies. Although roles for the prefrontal cortex, amygdala, hippocampus and mediodorsal thalamus in anxiety disorders are well documented, molecular mechanisms contributing to the functions of these structures are poorly understood. Here we report that deletion of Lynx2, a mammalian prototoxin gene that is expressed at hi...
متن کاملFemale oxytocin-deficient mice display enhanced anxiety-related behavior.
Previous studies have suggested that oxytocin (OT) may be anxiolytic in female laboratory rats and mice. The elevated plus-maze was used to compare anxiety-related behaviors of OT-deficient (OT-/-) and wild-type (OT+/+) mice. Female OT-/- mice displayed increased anxiety-related behavior compared with OT+/+ mice. The percentage of entries (P < 0.0002) and time spent (P < 0.003) in the open arms...
