Abstract
Nowadays, GSK3 is accepted as an enzyme strongly involved in the regulation of inflammation by balancing the pro- and anti-inflammatory responses of cells and organisms, thus influencing the initiation, progression, and resolution of inflammatory processes at multiple levels. Disturbances within its broad functional scope, either intrinsically or extrinsically induced, harbor the risk of profound disruptions to the regular course of the immune response, including the formation of severe inflammation-related diseases. Therefore, this review aims at summarizing and contextualizing the current knowledge derived from animal models to further shape our understanding of GSK3α and β and their roles in the inflammatory process and the occurrence of tissue/organ damage. Following a short recapitulation of structure, function, and regulation of GSK3, we will focus on the lessons learned from GSK3α/β knock-out and knock-in/overexpression models, both conventional and conditional, as well as a variety of (predominantly rodent) disease models reflecting defined pathologic conditions with a significant proportion of inflammation and inflammation-related tissue injury. In summary, the literature suggests that GSK3 acts as a crucial switch driving pro-inflammatory and destructive processes and thus contributes significantly to the pathogenesis of inflammation-associated diseases.

Abstract
Neuroinflammation contributes to the pathogenesis of several neurodegenerative disorders. Glycogen synthase kinase-3β (GSK-3β) regulates the release of proinflammatory cytokines and promotes inflammatory responses in immune cells. Microglia are the resident mononuclear immune cells of the central nervous system. Here, we investigated the anti-neuroinflammatory effects of (2S,3S,4R,5R,6S)-6-(2-(3,4-dimethoxyphenyl)-5,7-dimethoxy-4-oxo-4H-chromen-6-yl)-3,4,5-trihydroxy-N-((S)-1,1,1-trifluoropropan-2-yl)tetrahydro-2H-pyran-2-carboxamide (TFGF-18), a semisynthetic GSK-3β inhibitor, in lipopolysaccharide (LPS) activation of spontaneously immortalized SIM-A9 microglial cells and of mouse cortical microglia. TFGF-18 at 2.5 μM concentration inhibited LPS-induced production of nitric oxide by 56.3% and the proinflammatory cytokines TNF-α and IL-1β by 28.3 and 59.2% in SIM-A9 cells, respectively, relative to the LPS treatment control group. Pretreatment of mouse primary microglial cells with TFGF-18 at 2.5 μM concentration led to a reduction of 58.7% in TNF-α+ microglial cells at 24 h post-LPS stimulation. The migration of LPS-activated SIM-A9 cells was also reduced by 26.7% with pretreatment of TFGF-18 in a scratch assay. Analyses of signaling pathways demonstrated that TFGF-18 led to the suppression of LPS-induced GSK-3β activation and p65/NF-κB activity. Furthermore, the co-culture of SIM-A9 with SH-SY5Y neuroblastoma cells showed the suppression of TFGF-18 to microglia-mediated neurotoxicity in vitro. The findings indicate strong inhibitory effects of TFGF-18 on LPS-induced microglia activation via regulation of GSK-3β and downstream p65/NF-κB signaling. The results suggest a potential role of TFGF-18 in neuroprotection via its anti-neuroinflammatory effect.

Interleukin-10 Attenuates Behavioral, Immune and Neurotrophin Changes Induced by Chronic Central Administration of Interleukin-1β in Rats. Neuroimmunomodulation 2022; 29:380-390.

Abstract
BACKGROUND Activated microglia can trigger pro-inflammatory cytokine releases and neuroinflammation, which may inhibit astrocytes to produce neurotrophins and anti-inflammatory factors. Both eventually lead to neuron apoptosis or death. Furthermore, effective antidepressant or anti-dementia treatments can reduce pro-inflammatory cytokines, while enhance interleukin (IL)-10 production. However, the underline mechanism by which IL-10 modulates glial cell function, hence improves cognitive impairment or depression-like behavior is unknown. This study evaluated whether and how IL-10 attenuated chronic IL-1β administration-induced behavioral changes and the possible involved mechanisms. METHODS Rats received intracerebroventricular injection of IL-1β and/or IL-10 for 14 days. Then animal memory and depression-like behavior, pro-inflammatory cytokines, glial activities, expression of brain-derived neurotrophic factor (BDNF), Trk B, p75, and apoptosis-related genes were studied. RESULTS Compared to controls, significantly increased latent time and swimming distance in the Morris-water-maze, decreased sucrose consumption, and decreased locomotor and center zone entries in the open-field were found in rats administrated with IL-1β. These changes were associated with the reduction of GFAP expression, and concentrations of BDNF and anti-inflammatory cytokine IL-10, but the increase in the expressions of CD11b, TrkB, p75, and Caspase-3, the ratio of Bax/Bcl-2, and the concentrations of IL-1β, tumor necrosis factor-α, and IL-6. IL-10 treatment markedly attenuated IL-1β-induced above changes, except for the expressions of neurotrophin receptors. CONCLUSION IL-10-improved behavioral changes may be through suppressing microglia activity and inflammation, while restoring astrocyte function and BDNF expression.

Abstract
Alzheimer's disease (AD) is a serious neuropathologic disease characterized by aggregation of amyloid-β (Aβ) peptide. Aβ-mediated oxidative stress and neuroinflammation play crucial role in the development of AD. Engeletin is a flavononol glycoside that possesses anti-inflammatory effect. However, the effects of engeletin on AD have not been investigated. In the present study, we investigated the role of engeletin in AD using an in vitro AD model. Murine microglia BV-2 cells were stimulated with Aβ1-42 (5 μM) for 24 h to induce oxidative stress and inflammation. Our results showed that treatment with engeletin suppressed Aβ1-42-induced viability reduction and lactate dehydrogenase (LDH) release in BV-2 cells. Engeletin attenuated Aβ1-42-induced oxidative stress in BV-2 cells, as proved by decreased production of reactive oxygen species (ROS) and malonaldehyde (MDA) and increased glutathione peroxidase (GSH-Px) and superoxide dismutase (SOD) activities. Aβ1-42-induced nitric oxide (NO) production and inducible nitric oxide synthase (iNOS) expression were inhibited by engeletin treatment. Besides, engeletin inhibited Aβ1-42-induced production and mRNA levels of tumor necrosis factor-α (TNF-α), interleukin 1β (IL-1β), and interleukin 6 (IL-6). Engeletin enhanced Aβ1-42-induced activation of Kelch-like ECH-associated protein 1 (Keap1)/nuclear transcription factor E2-related factor 2 (Nrf2) signaling pathway in BV-2 cells. Inhibition of Keap1/Nrf2 signaling pathway reversed the inhibitory effects of engeletin on Aβ1-42-induced oxidative stress and inflammation in BV-2 cells. Taken together, engeletin attenuated Aβ1-42-induced oxidative stress and inflammation in BV-2 cells via regulating the of Keap1/Nrf2 pathway. These findings indicated that engeletin might be served as a therapeutic agent for the treatment of AD.

Abstract
The most important neuropathological features of Alzheimer's disease (AD) are extracellular amyloid-β protein (Aβ) deposition, tau protein hyperphosphorylation and activation of neurometabolic reaction in the brain accompanied by neuronal and synaptic damage, and impaired learning and memory function. According to the amyloid cascade hypothesis, increased Aβ deposits in the brain to form the core of the senile plaques that initiate cascade reactions, affecting the synapses and stimulating activation of microglia, resulting in neuroinflammation. A growing number of studies has shown that NF-κB and Wnt/β-catenin pathways play important roles in neurodegenerative diseases, especially AD. In this review, we briefly introduce the connection between neuroinflammation-mediated synaptic dysfunction in AD and elaborated on the mechanism of these two signaling pathways in AD-related pathological changes, as well as their interaction. Based on our interest in natural compounds, we also briefly introduce and conduct preliminary screening of potential therapeutics for AD.

Abstract
High sucrose can induce tau hyperphosphorylation and cognitive dysfunction/memory impairment as observed in Alzheimer's disease (AD). Rutaecarpine, a specific (transient receptor potential vanilloid 1 [TRPV1]) agonist, is neuroprotective against high sucrose diet-induced impairment, but detailed mechanisms are still elusive. In this study, we investigated whether rutaecarpine mitigates high sucrose diet-induced pathological alterations and cognitive in AD-like mice. Mice were administered fodder containing 0.01% rutaecarpine and 20% sucrose solution. Our results showed that rutaecarpine significantly attenuated high sucrose diet-induced spatial memory impairment and enhanced synaptic plasticity; rutaecarpine prevented high sucrose diet-induced tau hyperphosphorylation by decreasing glycogen synthase kinase-3β (GSK-3β) activity; activation of GSK-3β reversed the protective effect of rutaecarpine on learning and memory deficits, synaptic plasticity, and tau hyperphosphorylation induced by high-glucose diet significantly, suggesting that GSK-3β activation is required for high glucose-induced tau hyperphosphorylation. These results demonstrated that rutaecarpine can mitigate high sucrose diet-induced hyperphosphorylation of AD-associated tau protein and cognitive impairment by inhibiting GSK-3β, which supported that dietary rutaecarpine might have a promising use for therapeutic intervention of AD.

Abstract
The most common form of dementia is Alzheimer’s disease which is characterized by memory loss and cognitive disorders. The pathogenesis of Alzheimer’s disease is not known at present but toxicity of amyloid-beta is one of the central hypotheses. Amyloid-beta can stimulate the production of reactive oxygen species (ROS), cause oxidative stress, damage mitochondrial, cause inflammatory reactions and activate apoptosis related factors which lead to the neuronal death. In this study, we found that artemisinin, a first line antimalarial drug used in clinic for decades, improved the cognitive functions in Alzheimer’s disease animal model 3xTg mice. Further study showed that artemisinin reduced the deposition of amyloid-beta and tau protein, reduced the release of inflammation factors and apoptosis factors, and thereby reduced the neuronal cell death. Western blot assay showed that artemisinin stimulated the activation of ERK/CREB signaling pathway. Consistent with these results, artemisinin concentration-dependently promoted the survival of SH-SY5Y cell against toxicity of amyloid-beta protein 1-42 induced ROS accumulation, caspase activation and apoptosis. Artemisinin also stimulated the phosphorylation of ERK1/2 and CREB in SH-SY5Y cells in time and concentration-dependent manner. Inhibition of ERK/CREB pathway attenuated the protective effect of artemisinin. These data put together suggested that artemisinin has the potential to protect neuronal cells in vitro as well as in vivo animal model 3xTg mice via, at least in part, the activation of the ERK/CREB pathway. Our findings also strongly support the potential of artemisinin as a new multi-target drug that can be used for preventing and treating the Alzheimer’s disease.

Abstract
Tau neuronal and glial pathologies drive the clinical presentation of Alzheimer's disease and related human tauopathies. There is a growing body of evidence indicating that pathological tau species can travel from cell to cell and spread the pathology through the brain. Throughout the last decade, physiological and pathological tau have become attractive targets for AD therapies. Several therapeutic approaches have been proposed, including the inhibition of protein kinases or protein-3-O-(N-acetyl-beta-D-glucosaminyl)-L-serine/threonine Nacetylglucosaminyl hydrolase, the inhibition of tau aggregation, active and passive immunotherapies, and tau silencing by antisense oligonucleotides. New tau therapeutics, across the board, have demonstrated the ability to prevent or reduce tau lesions and improve either cognitive or motor impairment in a variety of animal models developing neurofibrillary pathology. The most advanced strategy for the treatment of human tauopathies remains immunotherapy, which has already reached the clinical stage of drug development. Tau vaccines or humanised antibodies target a variety of tau species either in the intracellular or extracellular spaces. Some of them recognise the amino-terminus or carboxy-terminus, while others display binding abilities to the proline-rich area or microtubule binding domains. The main therapeutic foci in existing clinical trials are on Alzheimer's disease, progressive supranuclear palsy and non-fluent primary progressive aphasia. Tau therapy offers a new hope for the treatment of many fatal brain disorders. First efficacy data from clinical trials will be available by the end of this decade.
