Hippocampal pituitary adenylate cyclase-activating polypeptide mediates rapid antidepressant-like effects of Yueju pill

Yueju pill, a classic Chinese Medicine formulated, was recently found to produce rapid antidepressant-like effects in a PKA-CREB signaling-dependent manner. In our study, we found that the Yueju pill induced a remarkable increase in PACAP. The intracerebroventricular injection of PACAP agonist induced a rapid antidepressant-like effect; conversely, the intrahippocampal infusion of a PACAP antagonist reversed the antidepressant response of the Yueju pill. Mice with hippocampal PACAP knockdown via viral-mediated RNAi displayed depression-like behavior. PACAP knockdown also blunted the antidepressant effect of the Yueju pill. PACAP knockdown resulted in down-regulated CREB and expression of the synaptic protein PSD95 at both baselines and after administration of the Yueju pill. However, administration of the Yueju pill in the knockdown mice promoted PACAP and PKA levels. Chronically stressed mice showed deficient hippocampal PACAP-PKA-CREB signaling and depression-like behavior, which were reversed by a single dose of the Yueju pill. In this study, we demonstrated that the up-regulation of PACAP induced activating of PKA-CREB signaling would play a part in the rapid antidepressant-like effects of the Yueju pill. We also identified iridoids fraction of Gardenia jasminoides Ellis (GJ-IF), a vital component of the Yueju pill, was identified to recapitulate rapid antidepressant-like behavior through increased hippocampal PACAP expression of the Yueju pill. The promotion of hippocampal PACAP may collectively represent a novel mechanism of rapid antidepressant-like effect.
