Numerous symptoms associated with neurodegenerative diseases, such as sleep disorders, anxiety, and mood alteration, are linked to circadian clock dysregulation. Dysregulation of the circadian system is increasingly implicated in the onset and progression of Alzheimer's disease, and emerging evidence highlights a bidirectional relationship between Alzheimer’s disease and circadian clock disruption. A crucial point is that the circadian clock regulates adult neurogenesis, a process that is significantly impaired in Alzheimer’s disease. Recent advancements suggest that the dynamic epigenetic mechanisms—including DNA and histone modifications as well as regulation by non-coding RNA—act as a critical regulation for circadian rhythms and neurogenesis. Therefore, research on circadian disruption and, particularly, focus on harmonising the circadian clock with neurogenesis in neurodegenerative diseases may also speed up the creation of innovative, circadian-based treatments to counteract the progress of neurological disorders from a new perspective.

APP and BACE1 are segregated in neurons, and mechanisms triggering their convergence have remained poorly understood, limiting therapeutic attempts to reduce Aβ production. Neural cell adhesion molecule 2 (NCAM2) is a cell surface localized protein, which increases Aβ levels via mechanisms that are not known. We show that APP binds to the extracellular domain of NCAM2. The intracellular domain of NCAM2 binds to the Rab11 adaptor protein Rab11-FIP5. The NCAM2/APP complex is endocytosed from the cell surface and targeted to BACE1-containing Rab11-positive recycling endosomes where it is processed. Convergence of APP with BACE1 is increased in transfected CHO cells and neurons expressing NCAM2. Consequently, the levels of amyloidogenic APP cleavage products are increased in cells expressing NCAM2. In NCAM2-deficient neurons, APP accumulates at the cell surface and in early endosomes, and APP levels in recycling endosomes are reduced. Aβ production is increased by Aβ oligomers and neuronal activity, and we show that the binding of NCAM2 to APP is increased in neurons treated with Aβ oligomers or after activation of synaptic NMDA receptors. Together, our data indicate that NCAM2 binds to APP and promotes APP targeting from the neuronal cell surface to recycling endosomes where APP is cleaved by BACE1. This novel mechanism regulating the convergence of APP and BACE1 in neurons can contribute to Aβ accumulation in Alzheimer’s disease.</div></div>","PeriodicalId":20851,"journal":{"name":"Progress in Neurobiology","volume":"251 ","pages":"Article 102807"},"PeriodicalIF":6.1,"publicationDate":"2025-08-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144732944","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}
