    • The present invention relates to nucleic acid sequences encoding brain derived neurotrophic factor (BDNF), as well as BDNF protein produced in quantity using these nucleic acid sequences, as well as fragments and derivatives thereof. In addition, the invention relates to pharmacologic compositions and therapeutic uses of BDNF, having provided, for the first time, the means to generate sufficient quantities of substantially pure BDNF for clinical use. In a specific embodiment, BDNF may be used to promote the survival of substantia nigra dopaminergic neurons and basal forebrain cholinergic neurons, thereby providing a method for treating, respectively, Parkinson's disease and Alzheimer's disease. The invention also relates to antibodies directed toward BDNF or fragments thereof, having provided a method for generating sufficient immunogen. Further, by permitting a comparison of the nucleic acid sequences of BDNF and NGF, the present invention provides for the identification of homologous regions of nucleic acid sequence between BDNF and NGF, thereby defining a BDNF/NGF gene family; the invention provides a method for identifying and isolating additional members of this gene family.
    • 本发明涉及编码脑源性神经营养因子(BDNF)的核酸序列,以及使用这些核酸序列量产生的BDNF蛋白质,以及其片段和衍生物。 此外,本发明涉及BDNF的药物组合物和治疗用途,其首次提供了产生足够量的用于临床使用的基本上纯的BDNF的方法。 在一个具体实施方案中,BDNF可用于促进黑质多巴胺能神经元和基础前脑胆碱能神经元的存活,从而提供分别治疗帕金森病和阿尔茨海默氏病的方法。 本发明还涉及针对BDNF或其片段的抗体,其提供了产生足够免疫原的方法。 此外,通过比较BDNF和NGF的核酸序列,本发明提供了鉴定BDNF和NGF之间的核酸序列的同源区,从而限定BDNF / NGF基因家族; 本发明提供了鉴定和分离该基因家族的其他成员的方法。
