Current clinical practice remains largely constrained to neurotransmitter-based symptomatic management, which can neither arrest upstream pathological progression nor restore lost neuronal populations. Emerging intervention strategies targeting immunosenescence, including senolytic agents, antioxidant and metabolic modulators, autophagy restoration, and precision-targeted nanocarrier delivery, have demonstrated substantial capacity to delay disease progression in preclinical and early clinical investigations. These strategies act through selective clearance of senescent immune cells, remodeling of the neuroinflammatory microenvironment, and restoration of cellular quality-control mechanisms. The multidimensional treatment strategy approaches from the perspectives of artificial intelligence (AI) guided target discovery, nanocarrier engineering, and gut microbiota intervention to simultaneously address multiple nodes in the immunosenescence network, thereby overcoming the inherent limitations of single-target strategies.

However, despite this strong disease association, the role of wild-type C9orf72 (wt-C9orf72) in neurodegeneration remains largely unexplored. HD is a neurodegenerative disease, and characterized by the accumulation of misfolded mutant Huntingtin (mHTT) and impaired proteostasis, yet the upstream mechanisms driving ubiquitin-proteasome system (UPS) dysfunction are not fully understood. Here, we identify a previously unrecognized modulatory role of wt-C9orf72 in regulating mHTT aggregation in experimental HD models. Analysis of public transcriptomic datasets reveal context-dependent C9ORF72 expression changes across HD-related human datasets, while C9orf72 levels are increased in R6/2 mouse brain lysates. Functional analyses reveal that overexpression of wt-C9orf72 increases mHTT aggregation and is accompanied by increased apoptotic signaling and reduced cell viability. Unbiased proteomic profiling identifies Stat1 as a key downstream effector. Mechanistically, wt-C9orf72 promotes Stat1 activation and nuclear translocation, leading to transcriptional upregulation of Isg15, a ubiquitin-like modifier. Elevated Isg15 disrupts UPS function, resulting in accumulation of polyubiquitinated proteins and impaired proteasomal degradation. Importantly, genetic suppression of Stat1 or Isg15 significantly attenuates C9orf72-associated mHTT aggregation, supporting a functional C9orf72-Stat1-Isg15 axis. Consistent with these cell-based findings, Stat1, phosphorylated Stat1 and Isg15 levels are elevated in the cortex and striatum of R6/2 HD mouse brains. Collectively, our findings identify a novel wt-C9orf72-Stat1-Isg15 axis that promotes proteasomal dysfunction and mHTT aggregation, providing new insights into wt-C9orf72-associated protein homeostasis.</div></div>","PeriodicalId":19159,"journal":{"name":"Neurotherapeutics","volume":"23 5","pages":"Article e00970"},"PeriodicalIF":7.4,"publicationDate":"2026-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148685001","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}

Among nrTK inhibitors, ibrutinib (RR = 0.62, 95% CI: 0.51–0.75) had a marked inverse association. Given the chemotherapeutic mechanisms of these medications, and the known cancer–PD inverse relationship, we performed a sensitivity analysis adjusting for relevant cancer subtypes, yielding a similar inverse association. Overall, the use of rTK and nrTK inhibitors was associated with a lower risk of developing PD, although there may be differential impact of this medication class depending on specific inhibition pathways.</div></div>","PeriodicalId":19159,"journal":{"name":"Neurotherapeutics","volume":"23 5","pages":"Article e01040"},"PeriodicalIF":7.4,"publicationDate":"2026-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148840778","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}
