Involvement of neuropeptide Y signaling in the antidepressant-like effect and hippocampal cell proliferation induced by kososan, a Kampo medicine, in the stress-induced depression-like model mice.

Neuropeptide Y (NPY) and Orexin-A (OX-A), well-known neuropeptides associated with feeding and arousal, show antidepressant-like properties via hippocampal cell proliferation. Previous studies have revealed that kososan, a Kampo (Japanese herbal) medicine, has an antidepressant-like effect in behavioral animal models of depression; the mechanisms underlying… CONTINUE READING
