Thirty-two, 8-week-old, male Wistar rats were divided into two groups: control rats and Dgal-treated rats (150 mg/kg/day; subcutaneously) for 18 weeks. At week 13, Dgal-treated rats were subdivided into three subgroups: (1) vehicle (DgV), (2) long-term treatment with 5ARIs, Finasteride 5 mg/kg/day, per oral for 6 weeks (DgF), (3) short-term treatment with 5ARIs, Finasteride 5 mg/kg/day, per oral for 2 weeks followed by a 4-week withdrawal period (DgW). Anxiety and depression were assessed using the elevated-plus maze (EPM) and splash test (ST). Blood was collected for biochemical analysis. After euthanasia, the brains were removed to examine brain inflammation, oxidative stress, neuroactive steroids, brain metabolites, and brain senescent markers. We found that DgV rats exhibited metabolic disturbance with a reduced preference index of the EPM, and grooming duration in ST. Increased brain neurotoxic metabolites, along with increased brain inflammation/oxidative stress, and reduced microglia complexity were observed in the DgV rats. Both therapeutic approaches improved metabolic parameters and preference index in the open arm of EPM in Dgal-treated rats, while grooming duration and microglia complexity were increased only in DgF rats. Our results indicate that Fin reduces depression-like and anxiety-like behaviors by reducing brain inflammation, oxidative stress, and brain senescent.

Cannabidiol (CBD), an active ingredient of <i>Cannabis sativa</i> L., is devoid of psychoactive actions and has gained attention for its anxiolytic, antioxidant, and anti-inflammatory properties, among others. This work aims to examine the potential anxiety-reducing properties of CBD in a well-established experimental mouse model of anxiety-like behavior induced by high doses of nicotine on male C57BL/6 mice. In this context, the open-field behavioral test was specially conducted to assess CBD's effects on anxiety-like behavior and locomotion.

During continuation with the auditory distractor task, the neural entrainment showed an occipital electrode distribution, suggesting the involvement of visual imagery. Unique to SMS continuation with the auditory distractor task, we found neural and sub-vocal (measured with electromyography) entrainment at the three-beat pattern frequency.

Consequently, we evaluated the impact of social adversity during early postnatal development (maternal separation [MS]), adulthood (social defeat [SD]), and a combined exposure (MS + SD) on behavioral outcomes (anxiety, motivation, anhedonia, and social interaction). We also examined cFos expression induced by social interaction in mPFC and hippocampus of adult male rats. Behavioral analyses revealed that SD-induced anhedonia, whereas MS + SD increased social interaction and mitigated SD-induced anhedonia. cFos evaluation showed that social interaction heightened plasticity in the prelimbic (PrL) and infralimbic (IL) cortices, dentate gyrus (DG), CA3, and CA1. Social interaction-associated plasticity was compromised in IL and PrL cortices of the MS and SD groups. Interestingly, social interaction-induced plasticity was restored in the MS + SD group.

In this review, we describe the prolific role of Stathmins in microtubule homeostasis with an emphasis on emerging roles for Stathmin-2 (Stmn2) in axon integrity and neurodegeneration. Stmn2 levels are altered in Amyotrophic Lateral Sclerosis and loss of Stmn2 provokes motor and sensory neuropathies. There is growing potential for employing Stmn2 as a disease biomarker or even a therapeutic target. Meeting this potential requires a mechanistic understanding of emerging complexity in Stmn2 function. In particular, Stmn2 palmitoylation has a surprising contribution to axon maintenance through undefined mechanisms linking membrane association, tubulin interaction, and axon transport.

{"title":"The Endocannabinoid System in Alzheimer's Disease: A Network Meta-Analysis","authors":"Yu Liu,&nbsp;Hang Xing,&nbsp;Yan Zhang,&nbsp;Yi Song","doi":"10.1002/jnr.25380","DOIUrl":"10.1002/jnr.25380","url":null,"abstract":"<div>\u0000 \u0000 <p>The findings concerning the association between endocannabinoid system (ECS) and Alzheimer's disease (AD) exhibited inconsistencies when examining the expression levels of endocannabinoids. This study aimed to provide a comprehensive summary of the studies regarding alterations of the ECS in AD. Six databases were thoroughly searched for literature to select relevant studies investigating the ECS in AD, including changes in cannabinoid receptors (CB1R and CB2R), endocannabinoids (2-AG and AEA), and their associated enzymes (FAAH and MAGL). Traditional meta-analysis evaluated the expression levels of the ECS in AD, and the results showed no significant differences in ECS components between healthy controls and AD patients. However, subgroup analysis revealed significantly lower expression levels of CB1R in AD than in controls, particularly in studies using western blot (SMD = −0.88, <i>p</i> &lt; 0.01) and in studies testing CB1R of frontal cortex (SMD = −1.09, <i>p</i> &lt; 0.01). For studies using HPLC, the subgroup analysis indicated significantly higher 2-AG levels in AD than in controls (SMD = 0.46, <i>p</i> = 0.02). Network meta-analysis examined the rank of ECS alterations in AD compared to controls, and the findings revealed that 2-AG and MAGL exhibited the largest increase and CB1R showed the largest decrease relative to the control group. Based on the findings of traditional meta-analysis and network meta-analysis, we proposed that AD patients may present decreased expression levels of CB1R and increased expression levels of 2-AG and its degrading enzyme MAGL. Our results may contribute to the growing body of research supporting the therapeutic potential of ECS modulation in the management of AD.</p>\u0000 </div>","PeriodicalId":16490,"journal":{"name":"Journal of Neuroscience Research","volume":"102 9","pages":""},"PeriodicalIF":2.9,"publicationDate":"2024-09-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142154398","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
