Abstract EN
Background.
The neurotrophic pathway regulated by the brain-derived neurotrophic factor (BDNF) plays a crucial role in the pathogenesis of poststroke depression (PSD).
How the traditional Chinese medicine compound preparation Xingnao Jieyu (XNJY) decoction regulates the neurotrophic pathway to treat PSD is unclear.
Objective.
This study aimed to investigate the antidepressant effect of XNJY decoction on a rat model of PSD and the molecular mechanism intervening in the neurotrophic pathway.
Methods.
After a middle cerebral artery occlusion model was established, chronic unpredictable mild stress was applied for 21 days to prepare a PSD model.
XNJY groups and a fluoxetine (Flu) group of rats were intragastrically administered with XNJY and Flu, respectively, for 21 consecutive days.
Depressive-like behaviors, including sucrose preference, open field test, and forced swimming test, were assessed.
The survival and apoptosis of cortical and hippocampal neurons were evaluated by immunofluorescence assay and TUNEL staining.
The contents of serotonin (5-HT), norepinephrine (NE), and BDNF in the cortex and hippocampus were determined by ELISA.
The protein levels of BDNF, p-ERK/ERK, and p-CREB/CREB in the cortical and hippocampal regions were tested by Western blot.
Results.
The depressive-like behaviors markedly improved after XNJY and Flu treatment.
XNJY and Flu promoted neuronal survival and protected cortical and hippocampal neurons from apoptosis.
XNJY also increased the contents of 5-HT, NE, and BDNF and recovered the protein levels of p-ERK/ERK, p-CREB/CREB, and BDNF in the cortical and hippocampal regions.
Conclusion.
These results indicated that the XNJY decoction exerts an obvious antidepressant effect, which may be due to the regulation of the BDNF/ERK/CREB signaling pathway.
