Neuronal damage is the main factor contributing to RTT, and the loss of MeCP2 function can result in reduced neuronal somas size, decreased dendritic abundance, and impaired neuronal function. While specific restoration of MeCP2 expression in neurons has been reported to partially rescue the behavioral phenotype and prolong the lifespan of mice, it cannot provide a complete cure. Therefore, other cells may be involved in the development of RTT. Although imaging and autopsy findings have revealed decreased white matter volume and corpus callosum thickness in RTT patients, the mechanisms underlying the development of white matter abnormalities remain unclear. These abnormalities are predominantly caused by damage to mature oligodendrocytes. This review provides an overview of the proliferation, differentiation, and function of oligodendrocyte lineage cells and elucidates the role of MeCP2 in these cells.","PeriodicalId":93251,"journal":{"name":"Ageing and neurodegenerative diseases","volume":"22 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2023-07-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"89765649","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The endocannabinoid (eCB) system, which is ubiquitously distributed in the brain and extensively involved in synaptic modulation, has been believed to play potential roles in neuronal circuit processes and related disorders. Although eCB-based pharmacological studies have made some clinical achievements, they still often encounter conflicting reports or undesired effects due to global manipulation of manifold brain regions and neuronal circuits, which impede the therapeutic application of eCB-based medications. In this review, we are devoted to discussing the versatile forms of eCB-mediated synaptic plasticity and dissecting currently well-studied specific cannabinoid circuits involved in behavioral domains which are closely linked to the organism’s survival and life quality, such as pain perception and stress-related emotion disorders. By gaining new insights into selective cannabinoid control in circuits, we can potentially mitigate the drawbacks of traditional pharmacology and facilitate the development of precision medicine with novel therapeutic strategies and drug discoveries.","PeriodicalId":93251,"journal":{"name":"Ageing and neurodegenerative diseases","volume":"8 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2023-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"79381757","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Exercise can regulate the expression of those AD-related genes or proteins through various epigenetic modulations, thereafter rescuing AD pathologies and improving cognitive deficits of AD. In this review, we briefly summarized recent research advances in the beneficial impacts of exercise on cognition and AD and discussed the underlying mechanisms from an epigenetic point of view, including DNA methylation, histone modifications, and non-coding RNAs. A deep understanding of how exercise epigenetically promotes cognitive and pathological recoveries in AD is crucial for the future discovery of precise exercise procedures or exercise-like remedies to treat this disease.","PeriodicalId":93251,"journal":{"name":"Ageing and neurodegenerative diseases","volume":"37 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2023-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"88217675","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Transmembrane protein 106B (TMEM106B) is a type II transmembrane lysosomal protein that participates in lysosome morphology, localization, acidification, and trafficking; t is involved in the pathogenesis of several NDs, especially frontotemporal lobular degeneration with TAR DNA-binding protein immunoreactive inclusions (FTLD-TDP). Studies from four independent research groups revealed that the luminal domain of TMEM106B (120-254aa) forms amyloid fibrils in several brain regions in patients with a series of NDs and neurologically normal older adults. Given its potentially critical roles in the pathogenesis of NDs and brain aging, this surprising finding has focused attention on TMEM106B and suggested that it is nearly as fundamental as other pathogenic amyloid proteins (e.g., Aβ, tau, α-syn); nevertheless, new questions surrounding TMEM106B must be asked. In this review,we firstly introduce the physiological function of TMEM106B and its involvement in NDs. Then, we elucidate the identification and cryo-electronic microscopic structure of TMEM106B fibrils and analyze the factors that contribute to the polymorphism of TMEM106B fibrils. Finally, the potential pathogenic role of TMEM106B fibrils is discussed, and the future directions for TMEM106 research in NDs are briefly summarized.","PeriodicalId":93251,"journal":{"name":"Ageing and neurodegenerative diseases","volume":"167 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2023-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"74218973","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In 2020, the disease was declared a pandemic by the World Health Organization. Although most COVID-19 patients primarily develop respiratory symptoms, neurological symptoms have been observed. Neurological symptoms are usually mild and non-specific. However, some patients could experience life-threatening neurological symptoms. With the increase in the incidence of COVID-19, the disease spectrum of patients with central and peripheral nervous system involvement has expanded significantly compared to the previous period. Lack of awareness has caused delays in diagnosis and treatment; therefore, updating the disease spectrum of neurological complications of COVID-19 is necessary. After COVID-19 claimed millions of lives, researchers found that some vaccines may induce autoimmune inflammatory responses in the nervous system via molecular mimicry, leading to SARS-CoV-2 vaccine-related neurological deficits. These neurological complications are often ignored by clinicians, delaying diagnosis and treatment; it is essential to study cases of vaccine-associated neurological complications. Therefore, we summarize the neurological complications of COVID-19 and nervous system adverse reactions caused by SARS-CoV-2 vaccines to help clinicians and public health service personnel understand these rare complications. Avoiding delays in diagnosis and treatment would ensure the safety of COVID-19 patients and SARS-CoV-2 vaccine recipients.","PeriodicalId":93251,"journal":{"name":"Ageing and neurodegenerative diseases","volume":"81 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2023-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"90249941","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
