Background The antidepressant effect of hyperoside (HYP), which is the main component of Hypericum perforatum , is not established. This study aimed to determine the effects of HYP on depression. Methods The antidepressant-like effect of HYP was studied in mice induced by chronic restraint stress (CRS). The effects of HYP on behavior, inflammation, neurotransmitters, gut microbiota, and short-chain fatty acids (SCFAs) were studied in CRS mice. Results HYP improved depressive-like behavior in mice induced by CRS. Nissl staining analysis showed that HYP improved neuronal damage in CRS mice. Western blot (WB) analysis showed that HYP increased the expression levels of BDNF and PSD95 in the hippocampus of CRS mice. The results of ELISA showed that HYP down-regulated the expression levels of IL-6, IL-1β, TNF-α, and CORT in the hippocampus, blood, and intestinal tissues of mice and up-regulated the expression levels of 5-HT and BDNF. Hematoxylin and eosin (HE) staining results indicate that HYP can improve the intestinal histopathological injury of CRS mice. The results of 16S rRNA demonstrated that HYP attenuated the dysbiosis of the gut microbiota of depressed mice, along with altering the concentration of SCFAs. Limitations In the present study, direct evidence that HYP improves depressive behaviors via gut microbiota and SCFAs is lacking, and only female mice were evaluated, which limits the understanding of the effects of HYP on both sexes. Conclusions HYP can improve CRS-induced depressive-like behaviors in mice, which is associated with regulating the gut microbiota and SCFAs concentration.

Nonylphenol (NP) exposure can trigger neurotoxicity and cause learning and memory impairment. Nicotinamide mononucleotide (NMN) has a therapeutic effect on neurodegenerative diseases , but the role of NMN on NP-induced learning and memory impairment is not known. Here, we examined the mitigative effect of NMN on the impaired learning and memory ability of rats exposed to NP. The NP impaired learning and memory in rats, while the low-dose intervention with NMN significantly prolonged the step-through latency of the PAT and improved the NAMPT and NMNAT1 content in brain tissue. At the same time, the NMN intervention also increased the content of 5-HTR 1A , 5-HTR 4 , and 5-HTR 6 related to learning and memory in the hippocampus. In line with this, we found that the NMN intervention activated the SIRT1/MAO-A pathway in brain tissue. NMN intervention, especially at 125 mg/kg doses, may improve rats’ NP-induced learning and memory impairment via the central 5-HT system and the NAD + /SIRT1/MAO-A pathway in the brain.

The present study was designed to examine the therapeutic effects of Botulinum neurotoxin A (BoNT/A) on depression-like behaviors in mice and to explore the potential mechanisms. These results revealed that a single facial injection of BoNT/A induced a rapid and prolonged improvement of depression-like behaviors in naïve and space-restriction-stressed (SRS) mice, reflected by a decreased duration of immobility in behavioral despair tests. BoNT/A significantly increased the 5-hydroxytryptamine (5-HT) levels in several brain regions, including the hippocampus and hypothalamus, in SRS mice. BoNT/A increased the expression of the N-methyl-D-aspartate receptor subunits NR1 and NR2B in the hippocampus, which were significantly decreased in SRS mice. Furthermore, BoNT/A significantly increased the expression of brain-derived neurotrophic factor (BDNF) in the hippocampus, hypothalamus, prefrontal cortex, and amygdala, which were decreased in SRS mice. Finally, BoNT/A transiently increased the levels of phosphorylated extracellular signal-regulated kinase (p-ERK) and cAMP-response element binding protein (p-CREB), which were suppressed in the hippocampus of SRS mice. Collectively, these results demonstrated that BoNT/A treatment has anti-depressant-like activity in mice, and this is associated with increased 5-HT levels and the activation of BDNF/ERK/CREB pathways in the hippocampus, supporting further investigation of BoNT/A therapy in depression.

Poly(5-hydroxytryptamine) (poly(5-HT)) is exploited as a new and efficient enzyme-immobilization matrix for amperometric and biofuel cell (BFC)-based biosensing. A GOx-poly(5-HT)-Pd nanoparticles (PdNPs) bionanocomposite is prepared by Na 2 PdCl 4 -initiated oxidized polymerization of 5-hydroxytryptamine (5-HT) in a neutral aqueous solution containing glucose oxidase (GOx), and this bionanocomposite and then chitosan (CS) are cast-coated on a Pd-plated Au electrode to yield a CS/GOx-poly(5-HT)-PdNPs/Pd plate /Au enzyme electrode. Scanning/transmission electron microscopy, UV–vis spectrophotometry and electrochemical quartz crystal microbalance are employed for material characterization and/or process monitoring. Under optimized conditions, the amperometric response of the enzyme electrode is linear with glucose concentration from 2.0 μM to 6.66 mM with a sensitivity of 110 μA mM −1 cm −2 , a limit of detection of 0.2 μM, and excellent operation/storage stability in the first-generation biosensing mode. The sensitivity is larger than those of some conventional electrodes under identical conditions. The enzyme electrode also works well in the second-generation biosensing mode. By using the enzyme electrode as the anode for glucose oxidation and a Pd plate /Au electrode as the cathode for KMnO 4 reduction, a monopolar BFC is constructed as a self-powered biosensor , the current response of which is linear with glucose concentration from 50 μM to 34.5 mM. Experiments also show that poly(5-HT) is a physical and chemical dual-immobilization matrix of enzyme, since the abundant amino groups in poly(5-HT) can be used for chemical bonding of GOx.

QMDDQ is peptide derived from shrimp that ameliorates scopolamine-induced memory impairment. In this study, behavioral experiments in mice showed that QMDDQ could reduce the latency, number of working memory errors of the total distance moved, number of reference memory errors, number of traversals of the original platform, and escape latency in mice. QMDDQ decreased AChE vitality and increased ACh, DA, and 5-HT content. HE staining revealed that the cells in the hippocampal areas exhibited a tight tissue structure, neat arrangement, clear outline, and no cell necrosis in the QMDDQ group. Immunohistochemistry showed that, the expression level of Notch1 protein was reduced, and that of the antibody antigen complex was reduced in the QMDDQ group. Immunofluorescence staining showed a decrease in the number of GFAP and Iba-1 of QMDDQ group. TEM revealed that the mitochondrial cristae are intact and clear of QMDDQ group. QMDDQ decreased expression levels of Notch 1, STAT3, HES1, GFAP, and Iba-1 and activated Notch1 signaling via western-blotting. Pharmacokinetic studies have shown that QMDDQ can be stably absorbed into the bloodstream, with absorption occurring within 12 h and metabolism being completed within 24 h. This study establishes a theoretical basis for active peptides to ameliorate memory impairment and initiates the development of memory-enhancing functional foods.

Background: Blast traumatic brain injury (bTBI) can result in depression-like behaviors in the acute and chronic phases. SSRIs have been shown to significantly alleviate depression-like behaviors in animal models of traumatic brain injury (TBI) by increasing serotonin (5-HT) and brain-derived neurotrophic factor (BDNF) in the hippocampus. However, the therapeutic effects of SSRIs on depression caused by bTBI remain unclear. Objective: Therefore, this study was aimed at investigating the therapeutic effects of SSRIs on depression-like behaviors in bTBI models. Methods: We created a rat model to study mild TBI by subjecting rats to increased blast overpressures (BOP) and injecting fluoxetine and escitalopram SSRIs intraperitoneally for 28 days. Results: On day 14 post-BOP exposure, rats treated with SSRIs showed decreased depression-like behaviors. This finding was accompanied by higher 5-HT levels in the hippocampus and increased numbers of Nestin-positive cells in the dentate gyrus. Furthermore, rats treated with SSRIs exhibited increased pCREB and BDNF protein expression in the hippocampus on days 7, 14, and 28 after bTBI. Conclusions: Overall, our findings indicate that SSRI-induced recovery from depression-like behaviors after mild bTBI is associated with the upregulation of 5-HT levels, pCREB and BDNF expression, and neurogenesis in the hippocampus.

Background: Migraine is a common neurovascular disorder with typical throbbing and unilateral headaches, causing a considerable healthcare burden on the global economy. This research aims to prepare chitosan-alginate (CS-AL) nanoparticles (NPs) containing Foshousan oil (FSSO) and investigate its potential therapeutic effects on the treatment of migraine. Methods: FSSO-loaded CS-AL NPs were prepared by using the single emulsion solvent evaporation method. Lipopolysaccharide (LPS)-stimulated BV-2 cells and nitroglycerin (NTG)-induced migraine mice were further used to explore anti-migraine activities and potential mechanisms of this botanical drug. Results: FSSO-loaded CS-AL NPs (212.1 ± 5.2 nm, 45.1 ± 6.2 mV) had a well-defined spherical shape with prolonged drug release and good storage within 4 weeks. FSSO and FSSO-loaded CS-AL NPs (5, 10, and 15 μg/mL) showed anti-inflammatory activities in LPS-treated BV-2 cells via reducing the levels of pro-inflammatory cytokines such as tumor necrosis factor-α (TNF-α), interleukin-1β (IL-1β), interleukin-6 (IL-6), and nitric oxide (NO), but elevating interleukin-10 (IL-10) expressions. Moreover, FSSO-loaded CS-AL NPs (52 and 104 mg/kg) raised pain thresholds against the hot stimulus and decreased acetic acid-induced writhing frequency and foot-licking duration in NTG-induced migraine mice. Compared with the model group, calcitonin gene-related peptide (CGRP) and NO levels were downregulated, but 5-hydroxytryptamine (5-HT) and endothelin (ET) levels were upregulated along with rebalanced ET/NO ratio, and vasomotor dysfunction was alleviated by promoting cerebral blood flow (CBF) in the FSSO-loaded CS-AL NPs (104 mg/kg) group. Conclusion: FSSO-loaded CS-AL NPs could attenuate migraine via inhibiting neuroinflammation in LPS-stimulated BV-2 cells and regulating vasoactive substances in NTG-induced migraine mice. These findings suggest that the FSS formula may be exploited as new phytotherapy for treating migraine.

ABSTRACT Background Migraine is widely recognized as the third most prevalent medical condition globally. Tianshu capsule (TSC), derived from “Da Chuan Xiong Fang” of the Jin dynasty, is integral in the clinical treatment of migraines. However, the chemical properties and therapeutic mechanisms of TSC different portions remain unclear. Purpose This study was designed to investigate the effects of TSC different portions (including small molecular TSCP-SM and polysaccharides TSC-P) on migraines and explore the underlying mechanisms. Study design and methods First of all, migraine rats were established by nitroglycerin injection and treated with TSC, TSC-P, and TSC-SM. ELISA, qPCR, and immunofluorescence were used to evaluate the pharmacological effects on migraine rats. Secondly, UPLC-Q/TOF-MS and GC-MS were employed to detect the components of TSCP-SM. PMP-HPLC, NMR, FT-IR, UV-Vis, AFM, and SEM were used for the chemical profiling of polysaccharides. Thirdly, the metabolic behavior profile of TSC-P was characterized by oral administrated fluorescence-labeled TSC-P and detected by NIR imaging. Finally, the anti-migraine mechanisms were explored by determining the composition of gut microbiota, analyzing colonic short-chain fatty acids (SCFAs), and examining serum tryptophan-related metabolites. Results Both small molecules (45 volatiles and 114 small molecules) and polysaccharides (including Glc, Ara, Gal, and Gal A) have exhibited effectiveness in alleviating migraines, and this efficacy is associated with reduced CGRP and iNOS levels, along with increased β -EP expressions. Further mechanistic exploration revealed that small-molecules exhibited effectiveness in migraines treatment by exerting antioxidative actions, while polysaccharides demonstrated superior therapeutic effects in regulating 5-HT levels. By monitoring the metabolic behavior of polysaccharides with fluorescent labeling, it was observed that TSC-P exhibited poor absorption. Instead, TSC-P demonstrated its therapeutic effects by modulating the aberrations in gut microbiota (including Alloprevotella, Muribaculaceae_ge , and Ruminococcaceae_UCG-005 ), cecum short-chain fatty acids (such as isobutyric, isovaleric, and valeric acids), and serum tryptophan-related metabolites (including indole-3-acetamide, tryptophol, and indole-3-propionic acid). Conclusion This research provides innovative insights into chemical composition, metabolic behavior, and proposed anti-migraine mechanisms of TSC from a polarity-based perspective, and pioneering an exploration focused on the polysaccharide components within TSC for the first time.

ObjectivesConstipation is a prevalent gastrointestinal issue, and the efficacy of probiotics in alleviating constipation has been well proved. This study aimed to investigate the impact of Bifidobacterium longum subsp. infantis NKU FB3-14 on loperamide- induced constipation by focusing on improving intestinal barrier function and modulating gut microbiota compositionMaterials and MethodsThe constipated model mice induced by loperamide were treated with NKU FB3-14, and the laxative effect was assessed based on the fecal water content, first black stool time and gastrointestinal transit rate. Gastrointestinal regulatory peptides in serum, intestinal neurotransmitter and inflammatory cytokines in colon tissues were measured using ELISA kits. Changes of gut microbiota composition were analyzed through 16S ribosomal DNA sequencing identification. Additionally, HPLC detection was performed to quantify short chain fatty acids levels in fecesResultsTreatment with NKU FB3-14 led to increase the fecal water content, shorten the first black stool time and improve small intestine transit rate. Motilin and substance-P significantly decreased in the model group, and only motilin increased in FB3-14 group; somatostatin and vasoactive intestinal peptide were decreased in model mice and both increased in FB3-14 group; 5-HT levels in the colon tissue were upregulated following NKU FB3-14 treatment. Histological examination revealed thinner colonic mucosa in the model group along with significant in TNF-α, IL-1β and IL-17 levels form the colon tissues which were all relieved by NKU FB 3-14 treatment. Furthermore, NKU FB3-14 intervention resulted in reduced abundance of Desulfobacterota and Desulfovibrio while increasing the abundance of Ruminococcaceae and Eubacterium; higher level of butyric acid was observed in fecesConclusionsIn summary, our findings demonstrated that NKU FB3-14 treatment significantly enhanced the intestinal motility, regulated the expression levels of gastrointestinal regulatory peptides, prevented damage to colonic barriers as well as ameliorated gut microbiota imbalance associated with loperamide-induced constipation.

Ethnopharmacological relevance According to traditional Chinese medicine (TCM) theory ( Yi Xue Zheng Zhuan ), the main factors associated with the pathogenesis of depression are deficiencies relating to five zang organs, Qi, and blood. Polygonatum sibiricum F. Delaroche (PS), which may avert these pathological changes, has been used in a variety of formulas to treat depression. However, the effects and mechanism of action of PS, alone, and especially those of its main active component PS polysaccharide (PSP), on depression remain unexplored. Aim of the study To determine the effects of PSP on depression-like behaviors and to elucidate its mechanism of action. Methods PSP was isolated from dried PS rhizomes and qualified using transmission electron microscopy and Fourier transform infrared spectroscopy . Lipopolysaccharide (LPS) and chronic unpredictable mild stress (CUMS)-induced depression models were used to evaluate the antidepressive effects of PSP. Veinal blood and brain tissue were collected to determine the levels of hippocampal 5-HT, serum cortisol (CORT), brain and serum cytokines, and hippocampal oxidation-related indicators. The protein expression levels of phosphorylated extracellular signal-regulated kinase (p-ERK1/2), nuclear factor kappa-light-chain-enhancer of activated B cells (NF-κB), glial fibrillary acidic protein (GFAP), phosphorylated protein kinase B (p-Akt), phosphorylation of the mammalian target of rapamycin (mTOR), caspase-3, GluA1 and GluA2, and GluN2A and GluN2B were determined using western blotting and immunofluorescence. Nissl staining was performed to detect histopathological changes in brain tissues. Results Injection of LPS ( i.p. ) induced depression-like behaviors, reduced the level of hippocampal 5-HT, increased the serum CORT level and hippocampal oxidative stress (ROS), and prompted the activation of ERK1/2, NF-κB, and GFAP and an inflammatory response. Conversely, PSP administration reduced these changes and prevented depression-like behaviors. PSP administration also promoted hippocampal expression of p-Akt, p-mTOR, GluA1, and GluA2; reduced the expression of caspase-3, GluN2A, and GluN2B; and prohibited the loss of granular cells in the DG region. Conclusion These results indicate that PSP prevents depression-like behaviors, and synaptic and neuronal damage probably by reducing ROS/HPA axis hyperfunction and the inflammatory response.

The prevalence of non-alcoholic fatty liver disease (NAFLD) and related mortality are increasing at an unprecedented rate. Traditional Chinese medicine (TCM) has been shown to offer potential for early prevention and treatment for NAFLD. This study examined the new mechanism of "Shenling Baizhu San" (SLBZS) in the prevention and treatment of NAFLD at the preclinical level.The male C57BL/6J mice were randomly divided into three groups: ND (normal diet), WDC (Western Diet+CCl4 injection) and WDC+SLBZS (SLBZS intervention). Body weight, energy intake, liver enzymes, pro-inflammatory factors and steatosis were recorded in detail. Meanwhile, TPH1, 5-HT, HTR2A and HTR2B were tested by qRT-PCR or ELISA. Dynamic changes in gut microbiota and metabolites were further detected through 16S rRNA gene and untargeted metabolomics.

Post-traumatic stress disorder (PTSD) is a serious mental disease featured by a stress dysfunction that occurs after an individual has faced intense mental stress, often accompanied by anxiety and chronic pain. Currently, the mainstream drug for PTSD is serotonin reuptake inhibitors (SSRIs), however, their pain management for patients is limited. Baicalein , a Chinese traditional herbal medicine, has shown promising results in treating anxiety, depression, and pain. In this study, we found that baicalein may alleviate single prolonged stress (SPS)-induced PTSD-like behaviors in mice without altering baseline nociceptive sensitivity or activity. Meanwhile, baicalein increased the noradrenaline (NE) and serotonin (5-HT) content and decreased the ratio of 5-hydroxyindoleacetic acid (5-HIAA)/5-HT by inhibiting the activity of monoamine oxidase A (MAO-A) in SPS-induce mice. The anxiolytic and antinociceptive effects induced by baicalein were totally abolished by 5-HT depleting agents. Moreover, the anxiolytic effects of baicalein could be abolished by the 5-HT 1A receptor antagonist WAY-100635, and the analgesic effects could be abolished by delta-opioid receptor antagonists in the spinal. Taken together, our study provides compelling evidence that baicalein reversed anxiety-like behaviors and neuropathic pain in PTSD through serotonergic system and spinal delta-opioid receptors.
