Currently, there are no effective treatments to cure or slow the progression of PD, highlighting an urgent need for new therapeutic strategies. Emerging evidence suggests that mesenchymal stem cells (MSCs) and fibroblast growth factor 21 (FGF21) are potential candidates for PD treatment. This study investigates a therapeutic strategy involving FGF21 delivered via mouse MSCs in the PD model of mice treated with 1-methyl-4-phenyl-1,2,3,6-tetrahydropyridine (MPTP) and dopaminergic SH-SY5Y cells exposed to 1-methyl-4-phenylpyridinium (MPP<sup>+</sup>). FGF21-overexpressing MSCs were administered intranasally, either before or after MPTP treatment in mice. Intranasally delivered FGF21-overexpressing MSCs efficiently migrated to the injured substantia nigra, ameliorated MPTP-induced PD-like motor deficits, reinstated dopaminergic neurons in the substantia nigra and nerve terminals in the striatum, as well as normalized brain-derived neurotrophic factor (BDNF) and FGF21 levels. In contrast, MSCs not overexpressing FGF21 showed limited or no impact on these parameters. In a PD cellular model of MPP<sup>+</sup>-treated SH-SY5Y cells, FGF21-overexpressing MSCs showed enhanced PD cell viability. Treatment with conditioned medium from FGF21-overexpressing MSCs or exogenous FGF21 prevented cell death, reduced mitochondrial reactive oxygen species (ROS), and restored neuroprotective proteins, including phospho-Akt, BDNF, and Bcl-2. These findings indicate that intranasal delivery of FGF21-overexpressing MSCs holds promise as a potential PD therapy, likely through activating the Akt-BDNF-Bcl-2 pathway, normalizing mitochondrial dysfunction, and mitigating dopaminergic neurodegeneration. Further clinical investigations are essential to validate these promising findings.</p>","PeriodicalId":19159,"journal":{"name":"Neurotherapeutics","volume":" ","pages":"e00501"},"PeriodicalIF":5.6,"publicationDate":"2024-11-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142751396","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}

These specialized cells are responsible for the critical clearance of debris and toxic proteins through endocytosis. However, activated microglia can secrete pro-inflammatory mediators, potentially exacerbating neuroinflammation and harming adjacent neurons. TREM2, a cell surface receptor expressed by microglia, is implicated in the modulation of neuroinflammatory responses. In this study, we investigated if and how Dehydroervatamine (DHE), a natural alkaloid, reduced the inflammatory phenotype of microglia and suppressed neuroinflammation. Our findings revealed that DHE was directly bound to and activated TREM2. Moreover, DHE effectively suppressed the production of pro-inflammatory cytokines, restored mitochondrial function, and inhibited NLRP3 inflammasome activation via activating the TREM2/DAP12 signaling pathway in LPS-stimulated BV2 microglial cells. Notably, silencing TREM2 abolished the suppression effect of DHE on the neuroinflammatory response, mitochondrial dysfunction, and NF-κB/NLRP3 pathways in vitro. Additionally, DHE pretreatment exhibited remarkable neuroprotective effects, as evidenced by increased neuronal viability and reduced apoptotic cell numbers in SH-SY5Y neuroblastoma cells co-cultured with LPS-stimulated BV2 microglia. Furthermore, in our zebrafish model, DHE pretreatment effectively alleviated behavioral impairments, reduced neutrophil aggregation, and suppressed neuroinflammation in the brain by regulating TREM2/NF-κB/NLRP3 pathways after intraventricular LPS injection. These findings provide novel insights into the potent protective effects of DHE as a promising novel TREM2 agonist against LPS-induced neuroinflammation, revealing its potential therapeutic role in the treatment of central nervous system diseases associated with neuroinflammation.</p>","PeriodicalId":19159,"journal":{"name":"Neurotherapeutics","volume":" ","pages":"e00479"},"PeriodicalIF":5.6,"publicationDate":"2024-11-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142751395","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}

One way to clear mHtt aggregates is to promote autophagy, which is disrupted in HD. Our previous studies showed that the small molecule p75 neurotrophin receptor (p75<sup>NTR</sup>) ligand, LM11A-31, prevented HD-related neuropathologies and behavioral deficits in multiple HD mouse models. This study investigated whether modulating p75<sup>NTR</sup> with LM11A-31, would reduce mHtt aggregates via autophagic/lysosomal mechanisms in HD models. LM11A-31 decreased mHtt aggregates in human neuroblastoma SH-SY5Y cells expressing mHtt (exon 1 with 74 CAG repeats) and in the striatum of R6/2 and zQ175dn mouse models of HD. The LM11A-31 associated decrease in mHtt aggregates in vitro was accompanied by increased autophagic/lysosomal activity as indicated by altered levels of relevant markers including p62/SQSTM1 and the lysosomal protease, mature cathepsin D, and increased autophagy flux. In R6/2 and/or zQ175dn striatum, LM11A-31 increased AMPK activation, normalized p62/SQSTM1 and LC3II levels, and enhanced LAMP1 and decreased LC3B association with mHtt. Thus, LM11A-31 reduces mHtt aggregates and may do so via engaging autophagy/lysosomal systems.

Using concurrent TMS and electroencephalogram (TMS-EEG), this study systematically compared the efficacy on cortical excitability and a typical clinical application (i.e. pain), between AiTBS with different intersession interval (ISIs) and 10-Hz rTMS. Participants received 10-Hz rTMS, AiTBS-15 (3 iTBS sessions with a 15-min ISI), AiTBS-50 (3 iTBS sessions with a 50-min ISI), or Sham stimulation over the primary motor cortex on four separate days. All four protocols included a total of 1800 pulses but with different session durations (10-Hz rTMS = 18, AiTBS-15 = 40, and AiTBS-50 = 110 min). AiTBS-50 and 10-Hz rTMS were more effective in pain reduction compared to AiTBS-15. Using single-pulse TMS-induced oscillation, our data revealed low gamma oscillation as a shared cortical excitability change across all three active rTMS protocols but demonstrated completely opposite directions. Changes in low gamma oscillation were further associated with changes in pain perception across the three active conditions. In contrast, a distinct pattern of TMS-evoked potentials (TEPs) was revealed, with 10-Hz rTMS decreasing inhibitory N100 amplitude and AiTBS-15 reducing excitatory P60 amplitude. These changes in TEPs were also covarying with low gamma power changes. Sham stimulation indicated no significant effect on either cortical excitability or pain perception. These results are relevant only for provoked experimental pain, without being predictive for chronic pain, and revealed a change in low gamma oscillation, particularly around the very particular frequency of 40 Hz, shared between AiTBS and high-frequency rTMS.
