[PMID: 37298512 DOI: 10.3390/ijms24119558] [Citation(s) in RCA: 8] [Impact Index Per Article: 8.0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/14/2023] [Revised: 04/18/2023] [Accepted: 05/04/2023] [Indexed: 06/12/2023] Open
Abstract
GM1 is one of the major glycosphingolipids (GSLs) on the cell surface in the central nervous system (CNS). Its expression level, distribution pattern, and lipid composition are dependent upon cell and tissue type, developmental stage, and disease state, which suggests a potentially broad spectrum of functions of GM1 in various neurological and neuropathological processes. The major focus of this review is the roles that GM1 plays in the development and activities of brains, such as cell differentiation, neuritogenesis, neuroregeneration, signal transducing, memory, and cognition, as well as the molecular basis and mechanisms for these functions. Overall, GM1 is protective for the CNS. Additionally, this review has also examined the relationships between GM1 and neurological disorders, such as Alzheimer's disease, Parkinson's disease, GM1 gangliosidosis, Huntington's disease, epilepsy and seizure, amyotrophic lateral sclerosis, depression, alcohol dependence, etc., and the functional roles and therapeutic applications of GM1 in these disorders. Finally, current obstacles that hinder more in-depth investigations and understanding of GM1 and the future directions in this field are discussed.

Antidepressant-like effect of Ganoderma lucidum spore polysaccharide-peptide mediated by upregulation of prefrontal cortex brain-derived neurotrophic factor. Appl Microbiol Biotechnol 2021; 105:8675-8688. [PMID: 34716786 DOI: 10.1007/s00253-021-11634-y] [Citation(s) in RCA: 8] [Impact Index Per Article: 2.7] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/09/2021] [Revised: 08/24/2021] [Accepted: 10/05/2021] [Indexed: 10/19/2022]
Abstract
A 28-kDa polysaccharide-peptide (PGL) with antidepressant-like activities was isolated from spores of the mushroom Ganoderma lucidum. It was unadsorbed on DEAE-cellulose. Its internal amino acid sequences manifested pronounced similarity with proteins from the mushrooms Lentinula edodes and Agaricus bisporus. The monosaccharides present in 28-kDa PGL comprised predominantly of glucose (over 90%) and much fewer galactose, mannose residues, and other residues. PGL manifested antidepressant-like activities as follows. It enhanced viability and DNA content in corticosterone-injured PC12 cells(a cell line derived from a pheochromocytoma of the rat adrenal medulla with an embryonic origin from the neural crest containing a mixture of neuroblastic cells and eosinophilic cells) and reduced LDH release. A single acute PGL treatment shortened the duration of immobility of mice in both tail suspension and forced swimming tests. PGL treatment enhanced sucrose preference and shortened the duration of immobility in mice exposed to chronic unpredictable mild stress (CUMS). Chronic PGL treatment reversed the decline in mouse brain serotonin and norepinephrine levels but did not affect dopamine levels. PGL decreased serum corticosterone levels and increased BDNF mRNA and protein levels and increased synapsin I and PSD95 levels in the prefrontal cortex. This effect was completely blocked by pretreatment with the BDNF antagonist K252a, indicating that PGL increased synaptic proteins in a BDNF-dependent manner.Key points• An antidepressive polysaccharide-peptide PGL was isolated from G. lucidum spores.• PGL protected PC12 nerve cells from the toxicity of corticosterone.• PGL upregulated BDNF expression and influenced key factors in the prefrontal cortex.

[PMID: 33402844 PMCID: PMC7778445 DOI: 10.2147/jpr.s283782] [Citation(s) in RCA: 14] [Impact Index Per Article: 3.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/27/2020] [Accepted: 12/12/2020] [Indexed: 12/11/2022] Open
Abstract
Background Depression is a prevalent and complex psychiatric disorder with high incidence in patients with chronic pain. The underlying pathogenesis of chronic pain-induced depression is complicated and remains largely unclear. An integrated analysis of endogenous substance-related metabolisms would help to understand the molecular mechanism of chronic pain-induced depression. Curcumin was reported to exert various health benefits, such as anti-depression, antioxidant, antineoplastic, analgesia, and anti-inflammation. Objective The aim of this study was to analyze the biomarkers related to depression in serum and to evaluate the anti-depression properties of curcumin in a chronic pain-induced depression model of rats. Design This is a randomized, controlled experiment. Setting This study was conducted at the Experimental Animal Center, Beijing Friendship Hospital, Capital Medical University. Methods Trigeminal neuralgia (TN) was produced by injecting 4 µL, 10% cobra venom saline solution into the infraorbital nerve (ION). Curcumin was administered by gavage twice a day from post-operation day (POD) 15 to POD 42. Mechanical allodynia was assessed using von Frey filaments. Sucrose preference and forced swimming tests were performed to evaluate depression-like behaviors. The metabolomics analysis was preceded by LCMS-IT-TOF and multivariate statistical methods for sample detection and biomarker screening. Results Cobra venom intra-ION injection led to chronic mechanical allodynia, reduced sucrose preference, and prolonged immobility during forced swimming. Curcumin treatment alleviated chronic mechanical allodynia, regained sucrose preference, and reduced immobility time. Differential analysis identified 30 potential metabolites changed under TN condition. The integrated analyses further revealed two major metabolic changes by comparing the serums from sham operated rats, TN rats, and TN rats treated with curcumin: 1) ether lipid metabolism; and 2) glycerophospholipid metabolism, and suggested that curcumin may improve chronic pain-induced depression by regulating these two types of lipid metabolisms. Conclusion Ether lipid and glycerophospholipid metabolism might be two of the pathways with the most potential related to chronic pain induced-depression; and curcumin could alleviate chronic pain induced-depression by modulating these two pathways. These results provide further insights into the mechanisms of chronic pain-induced depression and may help to identify potential targets for anti-depression properties of curcumin.

Abstract
Gangliosides are glycosphingolipids highly abundant in the nervous system, and carry most of the sialic acid residues in the brain. Gangliosides are enriched in cell membrane microdomains ("lipid rafts") and play important roles in the modulation of membrane proteins and ion channels, in cell signaling and in the communication among cells. The importance of gangliosides in the brain is highlighted by the fact that loss of function mutations in ganglioside biosynthetic enzymes result in severe neurodegenerative disorders, often characterized by very early or childhood onset. In addition, changes in the ganglioside profile (i.e., in the relative abundance of specific gangliosides) were reported in healthy aging and in common neurological conditions, including Huntington's disease (HD), Alzheimer's disease (AD), Parkinson's disease (PD), amyotrophic lateral sclerosis (ALS), stroke, multiple sclerosis and epilepsy. At least in HD, PD and in some forms of epilepsy, experimental evidence strongly suggests a potential role of gangliosides in disease pathogenesis and potential treatment. In this review, we will summarize ganglioside functions that are crucial to maintain brain health, we will review changes in ganglioside levels that occur in major neurological conditions and we will discuss their contribution to cellular dysfunctions and disease pathogenesis. Finally, we will review evidence of the beneficial roles exerted by gangliosides, GM1 in particular, in disease models and in clinical trials.

Abstract
BACKGROUND A prolonged exposure to ketamine triggers significant neurodegeneration and long-term neurocognitive deficits in the developing brain. Monosialotetrahexosylganglioside (GM1) can limit the neuronal damage from necrosis and apoptosis in neurodegenerative conditions. We aimed to assess whether GM1 can prevent ketamine-induced developmental neurotoxicity. METHODS Postnatal day 7 (P7) rat pups received 5 doses of intraperitoneal ketamine (20 mg/kg per dose) at 90-minute intervals for 6 hours. Cognitive functions, determined by using Morris water maze (MWM) including escape latency (at P32-36) and platform crossing (at P37), were compared among the ketamine-exposed pups treated with or without exogenous GM1 (30 mg/kg; n = 12/group). The effect of GM1 on apoptosis in hippocampus was determined by terminal deoxynucleotidyl transferase-mediated 2'-deoxyuridine 5'-triphosphate nick end labeling (TUNEL) staining and activated caspase 3 measurement. The hippocampal expression of brain-derived neurotrophic factor (BDNF), along with the phosphorylation of protein kinase B (AKT) and extracellular signal-related kinases 1 and 2 (ERK1/2), was detected by western blotting (n = 6/group). Anti-BDNF antibody (2 μg per rat) administered before GM1 treatment was applied to determine the neuroprotective mechanisms of GM1. RESULTS The rats receiving ketamine exposure experinced cognitive impairment in MWM test compared to the control rats, indicated by prolonged escape latency at P34 (P = .006), P35 (P = .002), and P36 (P = .005). However, in GM1-pretreated rats, ketamine exposure did not induce prolonged escape latency. The exogenous GM1 increased the platform-crossing times at P37 (3.00 ± 2.22 times vs 5.40 ± 1.53 times, mean ± standard deviation; P = .041) and reduced the hippocampal TUNEL-positive cells and cleaved-caspase 3 expression in ketamine-exposed young rats. Ketamine decreased BDNF expression and phosphorylation of AKT and ERK in the hippocampus, whereas exogenous GM1 blocked these ketamine-caused effects. However, for the ketamine-exposed rat pups receiving exogenous GM1, compared to immunoglobulin Y (IgY) isotype control, the BDNF-neutralizing antibody treatment counteracted the exogenous GM1-induced improvement of the escape latency at P36 (41.32 ± 12.37 seconds vs 25.14 ± 8.97 seconds, mean ± standard deviation; P = .036), platform-crossing times at P37 (2.16 ± 1.12 times vs 3.92 ± 1.97 times, mean ± standard deviation; P < .036), apoptotic activity, as well as AKT and ERK1/2 phosphorylation in the hippocampus of ketamine-challenged young rats. CONCLUSIONS Our data suggest that the exogenous GM1 acts on BDNF signaling pathway to ameliorate the cognitive impairment and hippocampal apoptosis induced by ketamine in young rats. Our study may indicate a potential use of GM1 in preventing the cognitive deficits induced by ketamine in the young per se.

Abstract
Sinomenine is a bioactive alkaloid extracted from Sinomenium acutum. Here, we investigated the antidepressant effects of sinomenine in mice. The antidepressant actions of sinomenine were first examined in the forced-swim test and the tail-suspension test, and then assessed in the chronic social defeat stress (CSDS) model of depression. Changes in the brain-derived neurotrophic factor (BDNF) signaling pathway after CSDS and sinomenine treatment were also investigated. A tryptophan hydroxylase inhibitor and a BDNF signaling inhibitor were also used to determine the pharmacological mechanisms of sinomenine. It was found that sinomenine induced antidepressant-like effects in the forced-swim test and tail-suspension test without affecting the locomotor activity of mice. Sinomenine also prevented the CSDS-induced depressive-like symptoms. Moreover, sinomenine fully restored the CSDS-induced decrease in the hippocampal BDNF signaling pathway, whereas a BDNF signaling inhibitor, but not a tryptophan hydroxylase inhibitor, blocked the antidepressant effects of sinomenine. In conclusion, sinomenine exerts antidepressant effects in mice by promoting the hippocampal BDNF signaling pathway.

Abstract
BACKGROUND Current antidepressants in clinical use always take weeks or even months to exert full therapeutic effects, and sometimes have serious side effects. Thus, it is very necessary to develop novel antidepressants with better efficacy and fewer adverse effects. The present study focused on investigating the antidepressant potential of matrine and its possible mechanisms of action. METHODS The forced swim test, tail suspension test, and chronic unpredictable mild stress model of depression were used to reveal the antidepressant-like effects of matrine on mice. Western blotting, immunohistochemistry, and lentivirus were further used together to explore the antidepressant mechanism of matrine. RESULTS It was found that matrine exhibited significant antidepressant actions in the forced swim test and tail suspension test without affecting the locomotor activity of mice. Chronic matrine administration fully reversed the chronic unpredictable mild stress-induced depressive-like symptoms in forced swim test, tail suspension test, and sucrose preference test. After that, western blotting analysis revealed that chronic matrine treatment restored the decreasing effects of chronic unpredictable mild stress on the PI3K/Akt/mammalian target of rapamycin signaling in hippocampus, but not prefrontal cortex. Furthermore, pharmacological and genetic blockade of the PI3K/Akt/mammalian target of rapamycin signaling in hippocampus abolished the antidepressant actions of matrine on mice. CONCLUSIONS Taken together, matrine produces antidepressant-like effects on mice via promoting the hippocampal PI3K/Akt/ mammalian target of rapamycin signaling.

Dihydromyricetin exerts a rapid antidepressant-like effect in association with enhancement of BDNF expression and inhibition of neuroinflammation. Psychopharmacology (Berl) 2018; 235:233-244.

Abstract
RATIONALE Major depressive disorder (MDD) is a highly prevalent illness that affects large populations across the world, and increasing evidence suggests that neuroinflammation and levels of brain-derived neurotrophic factor (BDNF) are closely related to depression. Dihydromyricetin (DHM) is a kind of flavonoid natural product that has been reported to display multiple pharmacological effects, including anti-inflammatory and anti-oxidative properties, and these may contribute to ameliorate MDD. OBJECTIVE This study investigated the effect of DHM on depression-related phenotypes in various experimental animal models. METHODS The antidepressant-like effect of DHM was validated via depression-related behavioral tests in naïve male C57BL/6 mice, as well as in the acute lipopolysaccharide-induced mouse model of depression. The chronic unpredicted mild stress (CUMS) mouse model of depression was also used to assess the rapid antidepressant-like effect of DHM by tail suspension test (TST), forced swimming test (FST), locomotor activity, and sucrose preference test (SPT). The expression of BDNF and inflammatory factors were determined through Western blotting and enzyme-linked immunosorbent assay, respectively. RESULTS DHM reduced immobility time in the TST and FST both in mice and the acute LPS-induced mouse model of depression. Seven days of DHM treatment ameliorated depression-related behaviors induced by CUMS, whereas similar treatment with the typical antidepressant venlafaxine did not. DHM activated the ERK1/2-CREB pathway and increased glycogen synthase kinase-3 beta (GSK-3β) phosphorylation at ser-9, with upregulation of BDNF expression, in both hippocampal tissues and cultured hippocampal cells. CONCLUSION The present data indicate that DHM exerts a more rapid antidepressant-like effect than does a typical antidepressant, in association with enhancement of BDNF expression and inhibition of neuroinflammation.

Abstract
Direct induction of macrophage ramification has been shown to promote an alternative (M2) polarization, suggesting that the ramified morphology may determine the function of immune cells. The ketone body metabolite β-hydroxybutyrate (BHB) elevated in conditions including fasting and low-carbohydrate ketogenic diet (KD) can reduce neuroinflammation. However, how exactly BHB impacts microglia remains unclear. We report that BHB as well as its producing stimuli fasting and KD induced obvious ramifications of murine microglia in basal and inflammatory conditions in a reversible manner, and these ramifications were accompanied with microglial profile toward M2 polarization and phagocytosis. The protein kinase B (Akt)-small RhoGTPase axis was found to mediate the effect of BHB on microglial shape change, as (i) BHB activated the microglial small RhoGTPase (Rac1, Cdc42) and Akt; (ii) Akt and Rac1-Cdc42 inhibition abolished the pro-ramification effect of BHB; (iii) Akt inhibition prevented the activation of Rac1-Cdc42 induced by BHB treatment. Incubation of microglia with other classical histone deacetylases (HDACs) inhibitors, but not G protein-coupled receptor 109a (GPR109a) activators, also induced microglial ramification and Akt activation, suggesting that the BHB-induced ramification of microglia may be triggered by HDACs inhibition. Functionally, Akt inhibition was found to abrogate the effects of BHB on microglial polarization and phagocytosis. In neuroinflammatory models induced by lipopolysaccharide (LPS) or chronic unpredictable stress (CUS), BHB prevented the microglial process retraction and depressive-like behaviors, and these effects were abolished by Akt inhibition. Our findings for the first time showed that BHB exerts anti-inflammatory actions via promotion of microglial ramification.

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 TSG. RESULTS TSG produced antidepressant-like effects in the FST and TST and also reversed the CSDS-induced depressive-like symptoms. Moreover, TSG treatment significantly restored the decreased hippocampal BDNF signaling pathway and neurogenesis in CSDS mice. Importantly, blockade of the hippocampal BDNF system fully abolished the antidepressant-like effects of TSG in mice. CONCLUSION In conclusion, TSG produces antidepressant-like effects in mice via enhancement of the hippocampal BDNF system.

The antidepressant-like effects of biperiden may involve BDNF/TrkB signaling-mediated BICC1 expression in the hippocampus and prefrontal cortex of mice. Pharmacol Biochem Behav 2017; 157:47-57. [PMID: 28216067 DOI: 10.1016/j.pbb.2017.02.004] [Citation(s) in RCA: 20] [Impact Index Per Article: 2.9] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 12/02/2016] [Revised: 02/13/2017] [Accepted: 02/15/2017] [Indexed: 12/28/2022]
Abstract
Preclinical and clinical studies suggest that neuronal muscarinic acetylcholine receptor (M-AchR) antagonists have antidepressant-like properties. Despite the recent interest in bicaudal C homolog 1 gene (BICC1) as a target for the treatment of depression, the upstream signaling molecules that regulate BICC1 are unknown, and very few studies have addressed the involvement of BICC1 in the antidepressant-like effects of the selective M1-AchR inhibitor, biperiden. Growing evidence indicates that activation of brain-derived neurotrophic factor (BDNF)/tropomyosin-related kinase receptor B (TrkB) signaling may be involved in antidepressant-like activities. In this study, we investigated the role of BDNF/TrkB signaling in the regulation of BICC1 expression in the chronic unpredictable stress (CUS) mouse model of depression. Furthermore, we also examined whether BDNF/TrkB signaling contributes to the antidepressant-like effects of biperiden via down-regulation of BICC1 in the hippocampus and prefrontal cortex of mice. Our current data show that CUS exposure induced significant depression-like behaviors, down-regulation of BDNF/TrkB signaling and up-regulation of BICC1 in the hippocampus and prefrontal cortex of mice. However, biperiden significantly alleviated the CUS-induced abnormalities. Moreover, we found that the effects of biperiden were antagonized by pretreatment with the TrkB antagonist K252a. Our results indicate that BDNF/TrkB signaling may be the major upstream mediator of BICC1 involvement in the antidepressant-like effects of biperiden.

Abstract
Alzheimer's disease (AD) is a most serious age-related neurodegenerative disorder accompanied with significant memory impairments in this world. Recently, microRNAs (miRNAs) have been reported to be invlolved in the pathophysiology of AD. Previous studies have shown that miRNA-206 (miR-206) is implicated in the pathogenesis of AD via suppressing the expression of brain-derived neurotrophic factor (BDNF) in the brain. Here, we examined the miR-206-3p and miR-206-5p expression in the hippocampus and cortex of Abeta precursor protein (APP)/presenilin-1 (PS1) transgenic mice treated with donepezil, a drug approved for treating AD in clinic. We found that the expression of miR-206-3p was significantly up-regulated in the hippocampus and cortex of APP/PS1 mice, while donepezil administration significantly reversed this dysfunction. In addition, enhancing the miR-206-3p level by the usage of AgomiR-206-3p significantly attenuated the anti-dementia effects of donepezil in APP/PS1 mice. Together, these results suggested that miR-206-3p is involved in the anti-dementia effects of donepezil, and could be a novel pharmacological target for treating AD.

Abstract
Current antidepressants are clinically effective only after several weeks of administration. Ginsenoside Rg3 is one component of ginsenosides, with a similar chemical structure to ginsenoside Rg1. Here, we investigated the antidepressant effects of Rg3 in mouse models of depression. The antidepressant actions of Rg3 were first examined in the forced swim test (FST) and tail suspension test (TST), and then assessed in the chronic social defeat stress (CSDS) model of depression. The changes in the hippocampal brain-derived neurotrophic factor (BDNF) signaling pathway after CSDS and Rg3 treatment were investigated. A tryptophan hydroxylase inhibitor and a BDNF signaling inhibitor were also used to determine the pharmacological mechanisms of Rg3. It was found that Rg3 produced antidepressant effects in the FST and TST without affecting locomotor activity. Rg3 also prevented the CSDS-induced depressive-like symptoms. Moreover, Rg3 fully restored the CSDS-induced decrease in the hippocampal BDNF signaling pathway, and use of the BDNF signaling inhibitor blocked the antidepressant effects of Rg3. In conclusion, ginsenoside Rg3 has antidepressant effects via promotion of the hippocampal BDNF signaling pathway.
