The ependymal cells close to the ventricular system rely on AJs with N-cadherin at the core to maintain their normal morphology and function. Therefore, it has an important impact on the function and disease of the central nervous system. Hydrocephalus is a pathological phenomenon of excessive cerebrospinal fluid accumulating in the ventricular system accompanied by continuous ventricular dilatation, which can be divided into obstructive hydrocephalus and communicating hydrocephalus according to the pathogenesis. Obstructive hydrocephalus is often associated with excessive ependymal cells produced by differentiation of radial glial cells. The etiology of communicating hydrocephalus is mainly related to the dyskinesia of cerebrospinal fluid. In addition, the damage of the brain barrier can lead to brain edema and aggravate the symptoms. At present, the researches on the pathogenesis of hydrocephalus are mainly focused on the development of ependymal cells and cilia, while less attention has been paid to molecules such as AJs, which play an important role in maintaining the polarity of ependymal cells. This paper discusses the formation and function of AJs and their role in preventing hydrocephalus by preserving the polarity of ependymal cilia, regulating the number of ependymal cells, and upholding the brain barrier integrity to impede hydrocephalus exacerbation, which provides a new direction for the study of hydrocephalus.</div></div>","PeriodicalId":13195,"journal":{"name":"IBRO Neuroscience Reports","volume":"18 ","pages":"Pages 283-292"},"PeriodicalIF":2.0,"publicationDate":"2025-02-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143349536","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 have previously reported that Cat-315-positive molecules were not expressed in the PNNs of the senescence-accelerated model (SAM)P10 strain model mice at 12 months of age.

In SAMP10 mice, Cat-315-positive PNNs were expressed in the primary somatosensory cortex early after birth, but their expression was significantly lower than that in SAMR1 mice.

However, an imbalance in Aβ production and clearance is the central pathological feature of Alzheimer’s disease (AD), leading to the accumulation of Aβ plaques in the brain. Low-density lipoprotein receptor-related protein 1 (LRP1) plays a critical role in both the central clearance of Aβ from the brain and its peripheral transport to visceral organs. Disruptions in these processes contribute to the accumulation of Aβ in the central nervous system (CNS) and the progression of AD. Recent research emphasizes the need for a broader focus on the systemic effects of organs outside the brain, particularly in the context of AD prevention and treatment. The contribution of peripheral systems, such as the liver, in Aβ clearance, is vital, given that Aβ levels in the plasma correlate closely with those in the brain. Consequently, targeting systemic processes, rather than focusing solely on the CNS, may offer promising therapeutic approaches. Furthermore, high-density lipoprotein (HDL) facilitates the formation of lipoprotein-amyloid complexes, which are important for Aβ transport and clearance, using proteins such as apolipoproteins E and J (ApoE and ApoJ) to form complexes that help manage Aβ accumulation. On the other hand, low-density lipoprotein (LDL) facilitates Aβ efflux from the brain by binding to LRP1, promoting its clearance. Given the relationship between lipid profiles and Aβ levels, along with lipid-modifying drugs, may be effective in managing Aβ accumulation and mitigating AD progression.</div></div>","PeriodicalId":13195,"journal":{"name":"IBRO Neuroscience Reports","volume":"18 ","pages":"Pages 191-199"},"PeriodicalIF":2.0,"publicationDate":"2025-01-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143093397","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}
