    • In methods for screening treatments for, and treatment of, neurodegenerative diseases, aggregation in neurons of NACP/α-synuclein is measured and expression of a non-amyloidogenic protein is stimulated in order to reduce the level aggregration. For purposes of screening agents for treatment of neurodegenerative disease, oxidative stress in the neuronal cells is stimulated by introducing a mixture of metal-ions and hydrogen peroxide. Examples of appropriate metals include iron, aluminum, and copper. After introduction of the agent under evaluation for stimulation of expression of non-amyloidogenic protein, the effectiveness is measured by testing for a decrease in the level of aggregation of NACP/α-synuclein. In an exemplary embodiment, the non-amyloidogenic protein is β-synuclein. The aggregation of NACP/α-synuclein is dependent upon the concentration of metal ions in the neuronal cells. In addition, the presence of chelating agents appears to modulate the build-up of NACP/α-synuclein aggregates which are responsible for synaptic and neuronal dysfunction.
    • 在用于筛选神经变性疾病的治疗和治疗方法中,测量NACP /α-突触核蛋白的神经元中的聚集,并刺激非淀粉样蛋白生成蛋白的表达以降低水平聚集。 为了筛选用于治疗神经变性疾病的药剂,通过引入金属离子和过氧化氢的混合物刺激神经元细胞中的氧化应激。 合适金属的实例包括铁,铝和铜。 在引入用于刺激非淀粉样蛋白形成蛋白表达的试剂之后,通过测试NACP /α-突触核蛋白的聚集水平的降低来测量有效性。 在一个示例性实施方案中,非淀粉样蛋白生成蛋白是β-突触核蛋白。 NACP /α-突触核蛋白的聚集取决于神经元细胞中金属离子的浓度。 此外,螯合剂的存在似乎调节负责突触和神经元功能障碍的NACP /α-突触核蛋白聚集体的积聚。

    • The invention provides compositions for increasing the clearance of protein aggregates, and pharmaceutical compositions comprising them, and methods for making and using them, including methods for accelerating protein aggregate clearance in the CNS, e.g., for treating diseases that are characterized by protein aggregation—including some degenerative neurological diseases such as Parkinson's disease. In one aspect, the compositions of the invention specifically target synuclein, beta-amyloid and/or tau protein aggregates, and the methods of the invention can be used to specifically prevent, reverse, slow or inhibit synuclein, beta-amyloid and/or tau protein aggregation. In alternative embodiments, the compositions and methods of the invention, are used to treat, prevent, reverse (partially or completely) or ameliorate (including slowing the progression of) degenerative neurological diseases related to or caused by protein aggregation, e.g., synuclein, beta-amyloid and/or tau protein aggregation. In one aspect, compositions and methods of this invention are used to treat, prevent or ameliorate (including slowing the progression of) Parkinson's disease, fronto-temporal dementia (FTD), Alzheimer's Disease (AD), Lewy body disease (LBD) and Multiple system atrophy (MSA).

    • The methodologies of the present invention demonstrate that a critical balance between pro- and anti-amyloidogenic molecules exists that regulates amyloid formation and cell death in Alzheimer's disease and Parkinson's disease. β-Synuclein, the non-amyloidogenic homologue of α-synuclein, is a negative modulator of α-synuclein and Aβ aggregation, having neuroprotective properties against α-synuclein and Aβ neurotoxicity and that β-synuclein and therapeutic agents derived therefrom block amyloidogenesis and neurodegeneration in vivo. The method of the present invention establishes that β-synuclein blocks Aβ aggregation either by direct inhibition of Aβ amyloidogenesis or indirectly via either α-synuclein or its 35 a.a. NAC region, inferring neuroprotective characteristics within the effected cells. The generation of a transgenic mouse line and a cell system overexpressing α-synuclein characterizes the mechanisms by which β-synuclein blocks α-synuclein and Aβ aggregation and that this mechanism offers protection to the cell against amyloid formation as seen in the pathologies of Alzheimer's disease and Parkinson's disease.
