    • The present invention relates generally to a method for preventing, inhibiting or otherwise reducing cell death. More particularly, the present invention contemplates a method for preventing, inhibiting or otherwise reducing neuronal cell death such as during neurodegenerative disease or following trauma The method of the present invention is generally practiced by the administration to a mammalian including a human subject, of an effective amount of an agent which blocks, retards or otherwise impairs ions from entering or passing through an ion channel. In one particular embodiment, the ion channel is a potassium (K) ion (K+) channel. The present invention further provides compositions comprising ion channel blockers and in particular K+ channel blockers. The compositions may also comprise other therapeutic agents such as agents which reduce levels of, or the activity of, a neurotrophin receptor. The present invention further provides methods for promoting cell survival by promoting intracellular cleavage of the neutrophil receptor by generating or introducing intracellular forms of the receptor such as by genetic or protein supplementation means. The present invention further provides a method for determining the likelihood of neurological cell degeneration by determining the level of function of K+ channels wherein an impaired ion channel is indicative of a reduced likelihood of neuronal cell apoptosis. Furthermore, the present invention provides antagonists of K+ channels, such as antagonists of molecules which mediate K+ channel activation via neurotrophin receptors or domains thereof.
    • 本发明一般涉及一种预防,抑制或以其他方式减少细胞死亡的方法。 更具体地,本发明考虑了一种预防,抑制或以其他方式减少神经元细胞死亡的方法,例如在神经退行性疾病期间或之后的创伤。本发明的方法通常通过向哺乳动物(包括人类受试者)施用有效的方法 阻止,阻滞或以其他方式损害离子进入或通过离子通道的试剂的量。 在一个具体实施方案中,离子通道是钾(K)离子(K +)通道。 本发明还提供了包含离子通道阻断剂,特别是K +通道阻断剂的组合物。 组合物还可以包含其它治疗剂,例如降低神经营养因子受体的水平或活性的试剂。 本发明还提供了通过产生或引入细胞内形式的受体,例如通过遗传或蛋白质补充方法来促进细胞内中性粒细胞受体的切割来促进细胞存活的方法。 本发明还提供了一种通过确定K +通道的功能水平来确定神经系统细胞变性的可能性的方法,其中受损的离子通道表示神经元细胞凋亡的可能性降低。 此外,本发明提供K +通道的拮抗剂,例如通过神经营养因子受体或其结构域介导K +通道活化的分子的拮抗剂。

    • The present invention relates generally to a method for modulating cell survival. Modulation of cell survival includes inducing, enhancing or otherwise promoting cell survival such as the survival of neural cells as well as facilitating cell death such as the death of targeted cancer cells. The modulation of cell survival is mediated by a region identified on the p75 neurotrophin receptor (p75NTR) required for death signalling. The present invention further provides genetic molecules which encode the death signalling region of p75NTR which are useful in antagonising death signal function as well as promoting cell death when expressed in targeted cells. The present invention also contemplates recombinant peptides, polypeptides and proteins s well as chemical equivalents, derivatives and homologues thereof which comprise the death signalling portion of p75NTR. Particularly useful molecules of the present invention comprise peptides corresponding to soluble forms of the death signalling portion of p75NTR. These molecules antagonise p75NTR-mediated cell death.
    • 本发明一般涉及调节细胞存活的方法。 细胞存活的调节包括诱导,增强或以其他方式促进细胞存活,例如神经细胞的存活以及促进细胞死亡,例如靶向癌细胞的死亡。 细胞存活的调节由死亡信号传导所需的p75神经营养因子受体(p75 NTR)鉴定的区域介导。 本发明进一步提供编码p75 NTR的死亡信号传导区的遗传分子,其可用于拮抗死亡信号功能以及当在靶细胞中表达时促进细胞死亡。 本发明还考虑重组肽,多肽和蛋白质以及其包含p75 NTR的死亡信号传导部分的化学等同物,衍生物和同系物。 本发明特别有用的分子包含对应于p75 NTR的死亡信号传导部分的可溶形式的肽。 这些分子拮抗p75 NTR介导的细胞死亡。
