VaD is linked to cerebrovascular lesions, such as those from white matter ischemia and chronic cerebral hypoperfusion, which can also occur in AD. Nitric oxide (NO) regulates cerebral blood flow (CBF) in the central nervous system. Memantine is an NMDA receptor antagonist approved for AD treatment. This study investigated the efficacy and molecular mechanism of MN-08, a novel memantine nitrate, in one VaD model (2VO) and two AD models (APP/PS1 mice and Aβ1-42-induced mice). MN-08 increased CBF, ameliorated cognitive and memory functions in VaD and AD, and was more effective than memantine. MN-08 increased the survival rate of CA1 neurons and mitigated white matter lesions and axonal damage. Moreover, MN-08 protected neurons from OGD-induced loss and promoted axonal outgrowth in the hippocampus by upregulating phosphorylated Akt (p-Akt), glycogen synthase kinase-3β (p-GSK3β), and high-molecular-weight neurofilaments (p-NFH). The beneficial effects of MN-08 were attenuated by carboxy-PTIO, a potent NO scavenger, suggesting that MN-08-derived NO may alleviate cognitive impairment from cerebral hypoperfusion. Taken together, our studies demonstrate that MN-08 is a promising therapeutic agent for the treatment of dementia including VaD and AD.</div></div>","PeriodicalId":19139,"journal":{"name":"Neuropharmacology","volume":"272 ","pages":"Article 110410"},"PeriodicalIF":4.6,"publicationDate":"2025-03-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143625423","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Although historical literature and observational studies suggest the potential clinical utility of psychedelics in treating PDs, rigorous research is lacking, and individuals with PDs are often excluded from modern psychedelic therapy trials. In the present review, we first discuss research on the effects of psychedelics in individuals with a PD through the conventional lens of the Diagnostic and Statistical Manual of Mental Disorders (5th ed., text rev.; DSM-5-TR) categorical model. Next, using the dimensional DSM Alternative Model of Personality Disorders (DSM-AMPD) as a framework, we examine how psychedelics may affect self-functioning, interpersonal functioning, and pathological personality traits.

We have investigated the function of KOPrs and MOPrs in single PVT neurons using whole-cell voltage-clamp recordings in brain slices from female and male mice (4–8 weeks). The majority of PVT neurons (69 %) co-expressed KOPr and MOPr. Activation of either receptor produced outward K<sup>+</sup> currents, with no age and sex differences. In neurons co-expressing both opioid receptors, the MOPr-induced K<sup>+</sup> current reversed around the theoretical equilibrium potential, whilst the KOPr current did not reverse at any holding potential tested. Furthermore, investigation of apparent inward currents produced by MOPr inverse agonists suggested the presence of tonically active MOPrs, predominantly in the anterior PVT. Activation of both KOPrs and MOPrs decreased glutamatergic input to PVT neurons by around 40 %, whereas only KOPr activation decreased GABAergic input, by 46 %. Together these data suggest that the balance of activation of KOPrs and MOPrs in the PVT plays a critical role in integrating stress- and reward-related signals.</div></div>","PeriodicalId":19139,"journal":{"name":"Neuropharmacology","volume":"272 ","pages":"Article 110407"},"PeriodicalIF":4.6,"publicationDate":"2025-03-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143616433","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Metabolomic analysis revealed altered levels of glutamate and γ-aminobutyric acid (GABA) in the CSF, indicating neurotransmitter imbalances. Transcriptomic profiling identified changes in genes related to synaptic plasticity, including PRKCG. PRKCG knockdown led to reduced CAMKII phosphorylation and GRIA1 expression, supporting its role in modulating synaptic plasticity.
