Although the aetiology of AD is still unknown, a perturbation of the immune system has been widely demonstrated in both animal experimental models and patients. The most studied aspect of immune reaction in AD is inflammation, which has been described to be implied in its pathogenic processes. Moreover, a growing body of evidence, indicating that the triggering of the specific AP immune response can be effective in reducing AD symptoms, suggest that a dysregulated network of innate and adaptive immune mechanisms could be critical in AD pathogenic process. The present short review, aimed to summarise some of the principal research studies on immune activation in AD, has the intent to provide suggestions useful to formulate new immune-therapeutic strategies for pathology treatment.","PeriodicalId":19198,"journal":{"name":"Neuroscience Research Communications","volume":"37 1","pages":"193-201"},"PeriodicalIF":0.0,"publicationDate":"2004-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"87080565","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}

AD is a neurodegenerative disorder characterized by the deposition of β-amyloid plaques in the brain parenchyma and neurofibrillary tangles comprised of hyperphosphorylated tau. APP plays a primary role in the pathogenesis of AD, because its processing generates the amyloid beta peptide (Aβ), the core of the amyloid plaque. APP has a large N-terminal extracellular domain and a short intracellular C-terminal domain that can be phosphorylated by various protein kinases.

In the last years of co-operation between ITINAD, Bracco Medical Department and Semeion Research Centre different kinds of experiments have been performed with ANNs in Alzheimer Disease context.

In the present study, the effects of 7-nitroindazole, which specifically inhibits nNOS, on apoptosis and cell proliferation int he dentate gyrus after transient global ischemia in gerbils were investigated. Enhanced apoptotic neuronal cell death and cell proliferation were observed in the dentate gyrus of ischemic gerbils. However, 7-nitroindazole suppressed the ischemia-induced apoptosis and cell proliferation. These results suggest that 7-nitroindazole has an inhibitive effect on apoptosis and cell proliferation following transient global ischemia.

To estimate the direction of glutamate transport by GLT-1, Na+ movement coupled with glutamate transport in astrocytes was analyzed in mixed astrocyte/neuron cultures. The rise in astrocytic intracellular Na+ due to glutamate exposure was suppressed by co-treatment with dihydrokainate (DHK). In contrast, the ouabain-induced rise in Na+ was significantly enhanced by DHK, suggesting that the role of GLT-1 was reversed. We then analyzed whether the reversal increased the amount of extracellular glutamate, and was crucial to excitotoxic neuronal death. Ouabain treatment resulted in a marked rise in glutamate and in neuronal death, and both the rise and cell death were significantly attenuated by DHK treatment.","PeriodicalId":19198,"journal":{"name":"Neuroscience Research Communications","volume":"17 1","pages":"150-163"},"PeriodicalIF":0.0,"publicationDate":"2004-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"76824984","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}

Antibodies against microtubule-associated protein (MAP2), glutamic acid decarboxylase (GAD) and tyrosine hydroxylase (TH) antigens showed that the cells had GABAergic and dopaminergic characteristics. The Campenot's assay revealed there were a number of peripheral nerveous system related neurons but they were rare. The cells also produced action potentials and responded to electrical stimulation by expressing calcium channels in the processes.
