Fig. (3). Long-term_increases in cAMP and P-CREB accompany antidepressant treatment.
Chronic, but not acute, antidepressant treatment enhances cAMP signaling by increasing Gαs-adenylyl cyclase coupling. Likewise, n-3 PUFAs also increase BDNF, a neurotropic factor increased with CREB phosphorylation, perhaps through enhancement of G-protein signaling. Modified from [50].
