    • The present invention provides for assay systems that may be used to detect and/or measure neurotrophin activity or to identify agents that exhibit neurotrophin-like activity, and for methods of using such assay systems. It is based, at least in part, on the discovery that the trkB protooncogene encodes a tyrosine kinase receptor that may serve as a functional binding protein for BDNF and NT-3. Such assay systems may be of particular value in identifying new neurotrophins or agents with neurotrophin-like activity. In various embodiments, the assay systems and methods of the invention may be used to detect and/or measure the binding of neurotrophin to trkB, either using direct binding studies or the detection of the secondary affects of trkB/neurotrophin binding. The present invention also has diagnostic and therapeutic utilities. In particular embodiments of the invention, methods of detecting aberrancies in trkB function or expression may be used in the diagnosis of neurological disorders. In other embodiments, manipulation of the trkB/neurotrophin interaction may be used in the treatment of neurological disorders, including Alzheimer's disease, Parkinson's disease, and amyotrophic lateral sclerosis (Lou Gehrig's disease).
    • 本发明提供了可用于检测和/或测量神经营养因子活性或鉴定表现出神经营养因子样活性的试剂的测定系统,以及使用该测定系统的方法。 至少部分基于trkB原癌基因编码可能作为BDNF和NT-3的功能性结合蛋白的酪氨酸激酶受体的发现。 鉴定新的神经营养蛋白或具有神经营养蛋白样活性的药剂时,这种测定系统可能是特别有价值的。 在各种实施方案中,本发明的测定系统和方法可以用于使用直接结合研究或trkB /神经营养因子结合的次级影响的检测来检测和/或测量神经营养因子与trkB的结合。 本发明还具有诊断和治疗用途。 在本发明的具体实施方案中,检测trkB功能或表达异常的方法可用于诊断神经障碍。 在其它实施方案中,trkB /神经营养因子相互作用的操作可用于治疗神经障碍,包括阿尔茨海默病,帕金森氏病和肌萎缩性侧索硬化(Lou Gehrig's disease)。
