While LRRK2 is known to modulate vesicular trafficking and stress signaling through its phosphorylation and kinase activity, how it responds to metabolic and environmental stressors remains poorly understood. Here, we show that acute inhibition of glycolysis and oxidative phosphorylation triggers rapid, reversible dephosphorylation of LRRK2 at constitutive sites in cells, <em>ex vivo</em> brain slices, and primary astrocytes. In contrast, glucose deprivation modestly increases LRRK2 kinase activity and Rab substrate phosphorylation. <em>In vivo</em>, chronic 2-deoxyglucose treatment reduces S935 phosphorylation in kidney tissue, linking energy stress to LRRK2 modulation in peripheral organs. Strikingly, manganese (Mn), a PD-relevant environmental toxicant, robustly activates LRRK2, inducing pS1292 autophosphorylation and phosphorylation of Rab8a, Rab10 and Rab12, while suppressing S935 phosphorylation after a 24 hrs exposure. Time-resolved analysis revealed distinct temporal substrate regulation, with rapid Rab12 phosphorylation and pRab10 levels gradually increasing and peaking only after 24 h. Phosphorylated Rab10 remains closely associated with both lysosomal and centrosomal membranes under Mn stress. Mn impaired mitochondrial respiration and increased ROS, and antioxidant treatment rescued Rab10 phosphorylation, establishing a redox-dependent mechanism of LRRK2 activation. Together, these findings reveal stressor-specific modes of LRRK2 regulation and suggest that LRRK2 integrates metabolic and environmental signals via redox-sensitive pathways relevant to PD pathogenesis.</div></div>","PeriodicalId":9083,"journal":{"name":"Brain Research","volume":"1863 ","pages":"Article 149785"},"PeriodicalIF":2.7,"publicationDate":"2025-06-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144298614","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Cellular viability and apoptotic responses were evaluated 24- and 48-hours post-treatment utilizing MTT assays and flow cytometry, while gene expression analysis of Bcl-2 and VEGF was performed using qRT-PCR. Furthermore, the scratch assay was employed to assess the impact of drug treatment on cellular migration. Notably, lower drug concentrations were required in 3D cultures due to enhanced cell-cell interactions, resulting in greater cytotoxicity and a marked inhibition of tumor cell proliferation. Significant downregulation of Bcl-2 and VEGF expression was observed, particularly a pronounced reduction in Bcl-2, which correlated with elevated apoptosis rates after 48 h. Furthermore, the apoptotic effect of combination therapy was confirmed, with an increase in death percentage in 48 h-3D treated groups, as expected (*P < 0.05 for monotherapy and ***P < 0.001 for combination).

Emerging evidence highlights the cyclic GMP-AMP synthase-stimulator of interferon genes (cGAS-STING) plays a pivotal role in the innate immune system by detecting cytosolic DNA and initiating type-1 interferons and pro-inflammatory responses. In NDDs, the accumulation of misfolded or mutant proteins compromises mitochondrial function, leading to the release of mitochondrial or nuclear deoxyribose nucleic acid (DNA) into the cytosol. This aberrant DNA sensing activates the cGAS-STING pathway, triggering sustained neuroinflammatory cascades and contributing to neuronal dysfunction and disease progression. Therefore, this review highlights the role of cGAS-STING pathway as a promising therapeutic target, with pharmacological inhibitors demonstrating the potential to attenuate disease pathology in animal models. Future directions should focus on translating cGAS-STING modulators into clinical applications, optimizing their specificity and safety, and integrating biomarker-based strategies to enable patient stratification and monitor therapeutic efficacy. Modulating this pathway offers a novel and exciting avenue for intervention in currently intractable neurodegenerative conditions.</p>","PeriodicalId":9083,"journal":{"name":"Brain Research","volume":" ","pages":"149784"},"PeriodicalIF":2.7,"publicationDate":"2025-06-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144301141","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
