    • A method for treating neurodegenerative diseases and conditions, particularly retinal neurodegenerative diseases by administering a spin-trap antioxidant compound is provided. In one embodiment, the compound is a spin-trap antioxidant such as alpha-phenyl-N-tert-butyl nitrone (PBN), a derivative or analogue thereof, that enhances survival of photoreceptor cells and may be used for treatment of retinal neurodegenerative diseases, including the dry form of macular degeneration. Also provided are methods for identifying and measuring the activity of spin-trap antioxidant compounds that enhance survival of retinal neuronal cells, such as photoreceptor cells.
    • 提供了通过施用自旋捕获抗氧化剂治疗神经变性疾病和病症,特别是视网膜神经变性疾病的方法。 在一个实施方案中,化合物是自旋捕获抗氧化剂,例如α-苯基-N-叔丁基硝酮(PBN),其衍生物或类似物,其可增强感光细胞的存活并且可用于治疗视网膜神经变性疾病 ,包括干燥形式的黄斑变性。 还提供了用于鉴定和测量增强视网膜神经细胞如感光细胞的存活的自旋捕获抗氧化剂化合物的活性的方法。

    • A cell culture system related to extended in vitro culture of mature retinal cells and methods for preparing the cell culture system are provided. Also provided is a retinal cell culture stress model related to extended in vitro culture of mature retinal cells in the presence of a stressor and methods for using the cell culture stress model. The invention provides a cell culture system comprising a long-term culture of mature retinal cells, without requiring addition of other types of non-retinal cells such as purified glia, or cells isolated from ciliary bodies within the eye, and the addition of a stressor such as light, A2E, cigarette smoke condensate, glutamate, or hydrostatic pressure. Methods for identifying bioactive agents that alter viability, neurodegeneration, or survival of retinal cells using the retinal cell culture stress system are also provided.
    • 提供了与延长的成熟视网膜细胞的体外培养有关的细胞培养系统和用于制备细胞培养系统的方法。 还提供了与在应激物存在下延长成熟视网膜细胞的体外培养相关的视网膜细胞培养应激模型以及使用细胞培养应激模型的方法。 本发明提供了细胞培养系统,其包含成熟视网膜细胞的长期培养物,而不需要添加其他类型的非视网膜细胞如纯化的神经胶质细胞或从眼内睫状体分离的细胞,并且加入应激物 如光,A2E,香烟烟雾冷凝物,谷氨酸盐或静水压力。 还提供了使用视网膜细胞培养应激系统来鉴定改变生存力,神经变性或视网膜细胞存活的生物活性剂的方法。
