Cholesterol metabolism has emerged as a critical factor involved with both central and peripheral dysregulation contributing to pathology. This review synthesizes current evidence on cholesterol's role in neurodegeneration and evaluates the therapeutic potential of statins, which act via cholesterol-dependent and other pleiotropic mechanisms. A PubMed search covering 1985-2025 publications was conducted using terms related to neurodegenerative diseases, statins, cholesterol metabolism, neuroinflammation, oxidative stress, mitochondrial dysfunction, and neuroprotection. Studies were selected to highlight mechanistic insights into cholesterol regulation in the nervous system and clinical data on statin use. Neuronal loss in neurodegeneration is driven by processes including excitotoxicity, inflammation, and mitochondrial dysfunction. Excessive reactive oxygen species activate apoptotic pathways involving <i>BAX</i>, <i>BAK</i>, and <i>p53</i>. Dysregulated cholesterol metabolism is a significant contributor: In AD, the <i>ApoE</i> allele <i>ε4</i> (<i>ApoE4</i>) links elevated cholesterol to amyloid-β (Aβ) accumulation and cognitive decline; in PD, cholesterol shows mixed effects, with some studies suggesting protection and others linking high levels to α-synuclein aggregation and mitochondrial impairment. In HD reduced cholesterol biosynthesis correlates with neuronal loss, while MS associates with elevated cholesterol and cognitive dysfunction. Statins, widely used cholesterol-lowering agents, reduce Aβ production, enhance its clearance, and improve synaptic function. Beyond lipid lowering, they exert anti-inflammatory, antioxidant, and anti-apoptotic effects. Clinical outcomes remain mixed, with benefits influenced by statin type, dose, treatment duration, disease stage, and patient genetics. Statins show multifaceted neuroprotective potential through cholesterol-dependent and independent pathways. While preclinical data are encouraging, clinical evidence is heterogeneous. Long-term, stratified trials are needed to clarify efficacy, and tailoring therapy to disease-specific mechanisms may offer a viable strategy for mitigating neurodegeneration and enhancing neuronal survival.</p>","PeriodicalId":74291,"journal":{"name":"Neuroprotection","volume":"4 1","pages":"30-47"},"PeriodicalIF":4.1,"publicationDate":"2026-02-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC13097634/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147791547","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

We specifically analyzed their roles in modulating immune responses within the CNS following injury and in neurodegenerative contexts. Bregs are a distinct immunosuppressive B cell subset that operates primarily via IL-10 secretion. Their functions include suppressing pro-inflammatory cytokine production and directing T cell differentiation toward regulatory phenotypes. In CNS pathologies, evidence suggests that Bregs can infiltrate the blood-brain barrier following disruption. Once within the CNS, they exert neuroprotection and enhance neuronal survival, thereby mitigating post-injury inflammation. Bregs are essential to immune regulation with significant, although not fully elucidated, neuroprotective potential. Their ability to modulate CNS makes them viable therapeutic targets for the treatment of brain injuries and neurodegenerative diseases.

Therapeutic effects arise from cell or enzyme replacement, trophic support, immunomodulation, and paracrine actions of the secretome.
