Remyelination therapies, which are currently under development, have a great potential to delay, prevent or even reverse disability in multiple sclerosis patients. Several models available study the effectiveness of novel compounds vivo, among is cuprizone model. This model characterized by toxin-induced demyelination, followed endogenous remyelination after cessation intoxication. Due its high reproducibility and ease use, this enjoys popularity various research industrial groups. In review article, we will summarize recent findings using discuss some identified promote

The development of neurodegenerative diseases is closely related to the disruption central nervous system homeostasis. Microglia, as innate immune cells, play important roles in maintenance homeostasis, injury response, and diseases. Lactate has been considered a metabolic waste product, but recent studies are revealing ever more physiological functions lactate. Lactylation an pathway lactate function involved glycolysis-related functions, macrophage polarization, neuromodulation, angiogenesis also implicated various This review provides overview homeostatic regulatory processes microglia lactylation, histone versus non-histone therapeutic approaches targeting Finally, we summarize current research on lactylation A deeper understanding mechanisms will provide options for treatment

Chronic pain is commonly linked with diminished working memory. This study explores the impact of anesthetic (S)-ketamine on spatial memory in a chronic constriction injury (CCI) mouse model, focusing gut microbiome. We found that multiple doses (S)-ketamine, unlike single dose, counteracted reduced spontaneous alteration percentage (%SA) Y-maze test, without affecting mechanical or thermal sensitivity. Additionally, repeated treatments improved abnormal composition microbiome (β-diversity), as indicated by fecal 16S rRNA analysis, and increased levels butyrate, key – brain axis mediator. Protein analysis showed these also corrected upregulated histone deacetylase 2 (HDAC2) downregulated brain-derived neurotrophic factor (BDNF) hippocampi CCI mice. Remarkably, microbiota transplantation from mice treated repeatedly to restored %SA hippocampal BDNF Butyrate supplementation alone %SA, BDNF, HDAC2 Furthermore, TrkB receptor antagonist ANA-12 negated beneficial effects impairment These results indicate administration ameliorates mice, mediated axis, primarily through enhancement signaling butyrate.

Multiple sclerosis (MS) is the most common demyelinating disease that attacks central nervous system. Dietary intake of cuprizone (CPZ) produces demyelination resembling patients with MS. Given role vagus nerve in gut-microbiota-brain axis development MS, we performed this study to investigate whether subdiaphragmatic vagotomy (SDV) affects CPZ-treated mice. SDV significantly ameliorated and microglial activation brain compared sham-operated Furthermore, 16S ribosomal RNA analysis revealed improved abnormal gut microbiota composition An untargeted metabolomic demonstrated blood levels metabolites mice Notably, there were correlations between or relative abundance several microbiome populations, suggesting a link brain. There also metabolites. Together, these data suggest CPZ through via nerve.

( R , S )- and )-ketamine have made significant progress in the treatment of treatment-resistant depression (TRD) become a research focus recent years. However, they both risks psychomimetic effects, dissociative abuse liability, which limit their clinical use. Recent preclinical studies shown that has more efficient lasting antidepressant effect with fewer side effects compared to )-ketamine. small-sample randomized controlled trial found although lower incidence adverse reactions adult TRD treatment, its efficacy is not superior placebo group, indicating advantage still needs further verification clarification. Moreover, an increasing body suggests might also applications prevention medical fields or diseases such as cognitive disorders, perioperative anesthesia, ischemic stroke, Parkinson’s disease, multiple sclerosis, osteoporosis, substance use inflammatory diseases, COVID-19, organophosphate poisoning. This article briefly reviews mechanism action on antidepressants related )-ketamine, fully revealing application potential development prospects, providing some references assistance for subsequent expanded research.

Chronic restrain stress (CRS) induces depression-like behaviors and demyelination in the brain; however, relationship between these remains unclear. Arketamine, (R)-enantiomer of ketamine, has shown rapid antidepressant-like effects CRS-exposed mice. We examined whether arketamine can improve both brains Additionally, we investigated role transforming growth factor β1 (TGF-β1) beneficial arketamine. A single dose (10 mg/kg) improved behavior corpus callosum Correlations were found this region. Furthermore, pretreatment with RepSox, an inhibitor TGF-β1 receptor, significantly blocked on Finally, a intranasal administration ameliorated The precise mechanisms by which contributes to remain These data suggest that CRS-induced may contribute behaviors, mitigate changes through TGF-β1-dependent mechanism.

The novel antidepressant arketamine, the (R)-enantiomer of ketamine, has been shown to ameliorate demyelination and facilitate remyelination in brains cuprizone (CPZ)-treated mice. However, mechanisms behind its effects remain unclear. Given role transforming growth factor β1 (TGF-β1) arketamine's antidepressant-like effects, we examined whether TGF-β1 also plays a on CPZ-treated Additionally, investigated intranasal these Repeated intermittent administration arketamine (10 mg/kg/day, twice weekly for last 2-weeks) attenuated corpus callosum (CC) CPZ (6 weeks)-treated Furthermore, pretreatment with RepSox mg/kg/day), an inhibitor TGF-β receptor 1, significantly blocked beneficial CC repeated (3.0 μg/kg/day, 2 weeks) ameliorated facilitated These data suggest that can mitigate facilitates mice through TGF-β1-dependent mechanism.

The spleen is a key immune-related organ that plays role in communication between the brain and immune system through brain-spleen axis brain-gut-microbiota axis. However, how gut microbiota affects function remains unclear. Here, we investigated whether microbiome depletion induced by administration of an antibiotic cocktail (ABX) function. Treatment with ABX for 14 days resulted significant decrease weight alterations splenic functions, including percentage neutrophils, NK cells, macrophages, CD8+ T cells. Furthermore, treatment large portion microbiota. Untargeted metabolomics analysis showed caused levels certain compounds plasma, spleen, brain. Moreover, decreased expression microglia marker Iba1 cerebral cortex. Interestingly, correlations were found abundance different components metabolites various tissues, as well cell populations weight. These findings suggest ABX-induced altered metabolite may affect gut-microbiota-spleen-brain
