Antidepressant-like effects of tetrahydroxystilbene glucoside in mice: Involvement of BDNF signaling cascade in the hippocampus.

ABSTRACT:

Background and aims

Current antidepressants in clinic need weeks of administration and always have significant limitations. Tetrahydroxystilbene glucoside (TSG) is one of the major bioactive ingredients of Polygonum multiflorum with neuroprotective effects. This study aimed to evaluate the antidepressant effects of TSG in mice.

Methods

The antidepressant-like effects of TSG in mice were examined in the forced swim test (FST), tail suspension test (TST), and chronic social defeat stress (CSDS) model of depression. The effects of CSDS and TSG on the hippocampal brain-derived neurotrophic factor (BDNF) signaling pathway and neurogenesis were further investigated. Moreover, the pharmacological inhibitors and lentiviral-shRNA were used to explore the antidepressant mechanisms of
