Abstract
RATIONALE Neuroinflammation can be alleviated via M2 microglia polarization, which could promote the recovery of perimenopausal depression. Astragalin (AST) possesses anti-neuroinflammatory activity. However, the effects of AST on perimenopausal depression and the molecular mechanism in regulating microglia polarization remained unknown. OBJECTIVES The purpose was to investigate the effects of AST on mice with simulated perimenopausal depression through regulating microglia polarization. It was aimed to clarify the molecular mechanism related to the interleukin-4 receptor (IL-4R)/janus kinase (JAK) 1/signal transducer and activator of transcription (STAT) 6 signaling pathway. METHODS The ovariectomy (OVX)/chronic unpredictable mild stress (CUMS)-induced murine model of perimenopausal depression was established and treated with AST. Then the depression-like behaviors and cognitive ability of mice were examined. After that, we detected the markers of microglia polarization and its regulatory signals. In addition, lipopolysaccharides (LPS)/adenosine triphosphate (ATP)-induced inflammatory BV2 model were used to verify the potential molecular mechanism. RESULTS AST alleviated perimenopausal depression-like behaviors and memory deficits. AST alleviated microglia activation and increased Ki67-positive cells in dentate gyrus (DG). The viability of BV2 decreased by LPS/ATP was raised by AST. Moreover, both in vivo and in vitro, AST switched microglia from M1 phenotype caused by OVX/CUMS or LPS/ATP to M2 phenotype. The IL-4R/JAK1/STAT6 signaling was restored, and the levels of inducible nitric oxide synthase (iNOS), nuclear NF-KappaB-p65 were reduced by AST. Importantly, AST showed prevention against the ubiquitination modification and degradation of STAT6. CONCLUSIONS Our results revealed new insights into molecular mechanism associated with microglia polarization in the effect of AST on the mouse model of perimenopausal depression.

Abstract
Xiaoyao Powder (XYP) has been widely applied in China to treat stress-related illnesses, such as migraine, depression, Parkinson’s disease, insomnia, and hypertension. Herein, this study aims to explore the effect of XYP on chronic unpredictable mild stress (CUMS)-induced depression and its underlying mechanisms. CUMS-induced depression rat models were established, they were subsequently randomly divided and treated with various conditions. Results of this study indicated that supplementation of XYP observably abolished CUMS-induced hippocampal damage and serum corticosterone (CORT) elevation. In mechanism, we discovered that CUMS induction could cause a prominent downregulation in glucocorticoid receptor (GR), phosphorylated-GR (p-GR), connexin 43 (Cx43), and brain-derived neurotrophic factor (BDNF), a remarkable upregulation in c-Src. While the introduction of XYP could reverse the changes in all of these indicators mediated by CUMS. Furthermore, we proved that Cx43 could interact with GR, and the protective effect of XYP on hippocampal neurons is realized by up-regulating GR. Summarized, this study indicated that XYP could ameliorate hippocampal neuron damage in CUMS-induced depression model rats through acting on Cx43/GR/BDNF axis.
