Neuropeptides and behavior: ACTH

Neurotrophic effects of ACTH/MSH neuropeptides.

Numerous experiments with peptides related to ACTH/MSH, and involving tests such as avoidance, approach, discrimination and rewarded behavior indicate that these peptides possess neuroactive effects on learning, motivation, attention, and concentration. In addition, ACTH/MSH neuropeptides affect social behavior, interact with opiate binding sites, and possess antiepileptic properties. Other CNS...

Editorial: Neuropeptides and Behavior: From Motivation to Psychopathology

Stress, neuropeptides, and feeding behavior: a comparative perspective.

Stress inhibits feeding behavior in all vertebrates. Data from mammals suggest an important role for hypothalamic neuropeptides, in particular the melanocortins and corticotropin-releasing hormone (CRH)-like peptides, in mediating stress-induced inhibition of feeding. The effects of CRH on food intake are evolutionarily ancient, as this peptide inhibits feeding in fishes, birds, and mammals. Th...

The Role of Neuropeptides in Suicidal Behavior: A Systematic Review

There is a growing evidence that neuropeptides may be involved in the pathophysiology of suicidal behavior. A critical review of the literature was conducted to investigate the association between neuropeptides and suicidal behavior. Only articles from peer-reviewed journals were selected for the inclusion in the present review. Twenty-six articles were assessed for eligibility but only 22 stud...
