  24. 24. Introduction A number of neurodegenerative diseases are associated with excitotoxic neuronal death [1]. However, the causes of nerve cell damage in these diseases have been hotly contested. The balance between kinase and phosphatase activity has been implicated in the pathogenesis of these diseases. The algal toxin okadaic acid (OA), an inhibitor of protein phosphatases 1 and 2A, has been shown to cause hyperphosphorylationof tau, modification of synapse structure, destruction of stablemicrotubules, and apoptosis in neurons [2]. It also kills a variety of cell types in culture, with disruption of the cell cytoskeleton [3]. Because OA induces neurodegenerative disease- like phenotypes in animals, it is often used to model these disorders [4]… However, although components of the MAP kinase signaling pathway have been implicated, the mechanism of this action of OA in neurons has remained unknown. In the current study, we investigated the signaling pathways affected by OA treatment in vitro, and the areas of the brains of male Wistar rats that were preferentially damaged by OA treatment, using hippocampal slice culture. We found that hippocampal cells, in particular, underwent non-apoptotic cell death via a MAP kinase-dependent mechanism.

  26. 26. Methods and Materials Materials. Culture media were obtained from Life Technologies (Gaithersburg, MD). Okadaic acid was purchased from Alexis Company (Läufelfingen,Switzerland). Antibodies to MEK1/2 and phosphorylated MAPK were purchased from New England Biolabs (Beverley, MA). Induction of cell death. Cell death was induced as described previously [15]. Briefly, cell death was induced by adding okadaic acid (0-300 nM, Alexis Co.) after washing slice cultures in serum-free medium. Light and electron microscopy. Cultures were fixed in 2.5% glutaraldehyde and 1% formaldehyde, treated with 1% OsO4 in 0.1 M phosphate buffer, pH 7.4, dehydrated in a graded series of ethanoland propylene oxide, and flat- embedded in an epoxy resin (DurcupanACM, Fluka, Neu-Ulm, Germany). Semithin sections were stainedwith toluidine blue, and ultrathin sections were stained with 1% uranyl acetate for 20 min and 1% lead citrate for 2 min. Statistics. For statistical analysis, 2-tailed Student’s t test was used to assess the significance of mean differences. Differences were considered significant at a P value of 0.05 or less.

  28. 28. Results Okadaic induces death of dentate gyrus neurons selectively. Hippocampal slice cultures treated with OA (1–300 nM) showed selective cell death of neurons in the dentate gyrus, but neurons in the CA1–3 regions were largely unaffected. Cell death occurred in a time- and dose-dependent manner. Propidium iodide staining of treated slides indicated…. Electron microscopy revealed a number of ultrastructural changes in hippocampal pyramidal neurons, particularly those in the CA3 region, in slices treated with 300 nM OA for 24 h (Fig 3). These changes included slight nuclear aggregations (arrow in Fig 3A), accumulation of mitochondria around nuclei (arrowheads in Fig 3B) and an increased amount of endoplasmic reticulum (Fig 3C). As shown in Figure 4, the nuclei of pyramidal neurons in the CA1 and CA3 regions… Involvement of MAPK signaling in the effect of OA. Compared with slices treated with medium only and treated slices at 0 h, slices treated with 300 nM OA showed increasing levels of phosphorylated MAPK at 4 h, 8 h, 16 h and 24 h, with no corresponding change in the levels of total MAPK. This increase was prevented in slices that were co-incubated with a protein kinase inhibitor. In addition, the levels of phosphorylated Tau were higher in OA-treated slices than in control slices… Edanz Group Japan | 28 Region-specific neuronal degeneration after okadaic acid administration Daniel P McGowan, Thomas da Costa, Richard Parris, Benjamin Shaw and Kerry A Greer Clear subheadings Graphics used to save space Clear comparisons made

  41. 41. Discussion The mechanisms underlying the excitotoxic neuronal cell death observed in a variety of neurodegenerative diseases have remained unclear, despite a large number of hypotheses being put forward. The neurotoxin OA induces neurodegenerative disease-like phenotypes and non-apoptotic cell death in animals. We investigated the signaling pathways involved in induction of this form of cell death in hippocampal slice cultures obtained from…. We observed selective neuronal cell death of dentate gyrus neurons in hippocampal slice cultures treated with OA (1–300 nM), occurring in a time- and dose-dependent manner. Neurons in the CA1–3 regions were relatively spared. However, electron microscopy revealed ultrastructural changes in pyramidal neurons in the CA3 region… These findings suggest that DG neurons in the hippocampus are particularly sensitive to OA, supporting the results of Wysong et al. [11] who described cell loss in the DG region of mice treated with OA. In contrast to the findings of Yim et al., who studied cultured Neuro2A cells, we observed a significant increase in the levels of phosphorylated MAPK in slices treated with OA. This difference could be due to the fact that…. In conclusion, by treating hippocampal slice cultures with OA and a variety of kinase and phosphatase inhibitors, we show that the excitotoxic cell death induced by this neurotoxin depends on MAPK activation and subsequent signaling. Future work should investigate the effects of protein kinase inhibitors on preservation of learning and memory functions in animals treated with OA.

  48. 48. Dear Dr Lisberger, Please find enclosed our manuscript entitled “Amyloid-like inclusions in the brains of Huntington’s disease patients”, by McGowan et al., which we would like to submit for publication as a Research Paper inNeuroscience. Recent immunohistochemical studies have revealed the presence of neuronal inclusions containing an N-terminal portion of the mutant huntingtin protein and ubiquitin in the brain tissues of Huntington’s disease (HD) patients; however, the role of these inclusions in the disease process has remained unclear. One suspected disease-causing mechanism in Huntington’s disease and other polyglutamine disorders is the potential for the mutant protein to undergo a conformational change to a more stable anti-parallel β-sheet structure… To confirm if the immunohistochemically observed huntingtin- and ubiquitin-containing inclusions display amyloid features, we performed Congo red staining and both polarizing and confocal microscopy on post-mortem human brain tissues obtained from five HD patients, two AD patients, and two normal controls. Congo red staining revealed a small number of amyloid-like inclusions showing green birefringence by polarized microscopy, in a variety of cortical regions.... ….detected inclusions observed in parallel sections, suggesting that only a relatively small proportion of inclusions in HD adopt an amyloid-like structure. We believe our findings would appeal to a broad audience, such as the readership ofNeuroscience. As a wide-reaching journal publishing original research on all aspects of neuroscience… We confirm that this manuscript has not been published elsewhere and is not under consideration by another journal.
