    • A novel polypeptide, designated neurotrophic factor-4 (NT-4), has been identified by PCR amplification of human genomic DNA. Provided herein is nucleic acid encoding NT-4 useful in diagnostics and in the recombinant preparation of NT-4. Also provided herein are nucleic acids encoding naturally occurring amino acid sequence variants of NT-4, designated NT-4&bgr;, NT-4&ggr;, and NT-4&Dgr;. The neurotropic factors of the invention are useful in the treatment of nerve cells and in diagnostic assays.

    • The present invention relates to neuronal formation and methods of treating diseases characterized by abnormalities in the activity of dopaminergic (DA) and serotonergic (5HT) neurons. In particular, the invention relates to a method of forming serotonergic neurons in vitro by contacting neuroprogenitor cells to an effective amount of native sequence, variants and functional fragments of FGF-4, FGF-8 and Shh. Additionally, disclosed is a method for forming dopaminergic neurons by contacting neuroprogenitor cells to an effective amount of FGF-8 and Shh. Further described are compositions, cell culture compositions and medical devices which contain sufficient amount of FGF-8, Shh or FGF-8, Shh and FGF-4 to stimulate differentiation into dopaminergic or serotonergic neurons, respectively. Further described are methods of using serotoneurgic neurons to treat disorders relating to food intake, hormone secretion, stress response, pain and immune function, sexual activity, cardiovascular function and temperature regulation, in particular, depression, proclivity to suicide, violent aggressive behavior, obsessive-compulsive behavior and anorexia/bulimia and schizophrenia. Further described are methods of using dopaminergic neurons to treat disorders relating postural reflexes, movement and reward-associated behaviors, specifically, Parkinson's disease, schizophrenia and drug addiction. Further described is the coadministration of a neuronal survival factor, for example, NGF, CNTF, BDNF, NT-3, NT-4, aFGF, IL-1&bgr;, TNF&agr;, IGF-1, IGF-2, TGF-&bgr;, TGF-&bgr;1 or skeletal muscle extract.
    • 本发明涉及神经元形成和治疗特征为多巴胺能(DA)和5-羟色胺能(5HT)神经元活性异常的疾病的方法。 特别地,本发明涉及通过将神经祖细胞与FGF-4,FGF-8和Shh的有效量的天然序列,变体和功能片段接触而在体外形成血清素能神经元的方法。 此外,公开了通过使神经祖细胞与有效量的FGF-8和Shh接触来形成多巴胺能神经元的方法。 进一步描述的是组合物,细胞培养组合物和含有足量的FGF-8,Shh或FGF-8,Shh和FGF-4分别刺激分化为多巴胺能或5-羟色胺能神经元的医疗装置。 进一步描述的是使用血清素治疗神经元治疗与食物摄入,激素分泌,应激反应,疼痛和免疫功能,性活动,心血管功能和温度调节有关的疾病,特别是抑郁症,倾向于自杀,暴力侵略行为,强迫症 - 疲劳行为和厌食/贪食和精神分裂症。 进一步描述的是使用多巴胺能神经元来治疗与姿势反射,运动和回报相关行为相关的疾病,特别是帕金森病,精神分裂症和药物成瘾的方法。 进一步描述的是神经元存活因子例如NGF,CNTF,BDNF,NT-3,NT-4,aFGF,IL-1β,TNFα,IGF-1,IGF-2,TGF-β,TGF- β1或骨骼肌提取物。
