摘要:
L'invention concerne des systèmes d'analyses qui peuvent être utilisés pour détecter et/ou mesurer l'activité de la neurotrophine et pour identifier des agents ayant une activité semblable à celle de la neurotrophine. L'invention se base, au moins en partie, sur la découverte que le proto-oncogène trkB code un récepteur de la tyrosine kinase qui peut servir de protéine de liaison fonctionnelle pour BDNF et NT-3. L'invention concerne également des procédés diagnostiques et thérapeutiques fondés sur l'interaction entre BDNF et/ou NT-3 et trkB, et pour plusieurs molécules réceptrices d'orphan.
摘要:
The present invention provides for an isolated nucleic acid molecule encoding a human TIE-2 ligand. In addition, the invention provides for a receptor body which specifically binds a human TIE-2 ligand. The invention also provides an antibody which specifically binds a human TIE-2 ligand. The invention further provides for an antagonist of human TIE-2. The invention also provides for therapeutic compositions as well as a method of blocking blood vessel growth, a method of promoting neovascularization, a method of promoting the growth or differentiation of a cell expressing the TIE-2 receptor, a method of blocking the growth or differentiation of a cell expressing the TIE-2 receptor and a method of attenuating or preventing tumor growth in a human.

摘要:
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. It is based, at least in part, on the discovery that the trkB proto-oncogene encodes a tyrosine kinase receptor that may serve as a functional binding protein for BDNF and NT-3. The present invention also provides for diagnostic and therapeutic methods based on the interaction between BDNF and/or NT-3 and trkB, and for a number of orphan receptor molecules.

摘要:
The present invention relates to neurotrophin-3 (NT-3), a newly discovered member of the BDNF gene family. It is based, in part, on the identification of regions of nucleic acid sequence homology shared by BDNF and NGF (U.S. patent application Serial No. 400,591, filed August 30, 1989, incorporated by reference herein). According to the present invention, these regions of homology may be used to identify new members of the BDNF/NGF gene family; such methodology was used to identify NT-3. The present invention provides for the genes and gene products of new BDNF/NGF related neurotrophic factors identified by these methods. According to the invention, NT-3 may be used in the diagnosis and/or treatment of neurologic disorders, including, but not limited to, Alzheimer's disease and Parkinson's disease. Because NT-3 has been observed to exhibit a spectrum of activity different from the specificities of BDNF or NGF, NT-3 provides new and valuable options for enducing regrowth and repair in the central nervous system.
摘要:
L'invention concerne la neurotrophine-3 (NT-3), un élément nouvellement découvert de la famille des gènes BDNF. L'invention se fonde en partie sur l'identification de régions d'homologie de fréquence d'acides nucléiques partagée par BDNF et NGF (demande de brevet d'invention US No. 400,591, déposée le 30 Août 1989, citée en référence dans la présente invention). Selon la présente invention, ces régions d'homologie peuvent être uilisées pour identifier de nouveaux éléments de la famille des gènes BDNF/NGF; une telle méthodologie a été utilisée pour identifier NT-3. La présente invention fournit les gènes et les produits génétiques des nouveaux facteurs neurotrophiques relatifs à BDNF/NGF identifiés par ces procédés. Selon l'invention, NT-3 peut être utilisé dans le diagnostic et/ou le traitement de troubles neurologiques, y compris mais de manière non exhaustive, la maladie d'Alzheimer et la maladie de Parkinson. Etant donné qu'on a observé que NT-3 présente un spectre d'activité différent des spécificités de BDNF ou NGF, NT-3 offre de nouvelles options intéressantes pour induire la reprise de la croissance et la réparation du système nerveux central.
