    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, 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).

    摘要: The present invention relates to chimeric neurotrophic factors which comprise at least a portion of a naturally occurring cellular factor and a portion of at least one other molecule such that the resulting chimeric molecule has neurotrophic activity. It is based, in part, on the discovery that chimeric molecules comprising portions of both NGF and BDNF are likely to possess neurotrotrophic activity, and in some cases exhibit a spectrum of activity larger than that of either parent molecule. It is further based on the discovery that chimeric molecules comprising neurotrophic factor sequences as well as additional peptide sequences may retain neurotrophic activity, and in some cases may exhibit a more potent activity than the parent factor. The chimeric neurotrophic factor molecules of the invention provide a number of advantages relative to naturally occurring neurotrophic factors. Chimeric neurotrophic factors may be used to provide, for example, the activity of two neurotrophic factors in a single molecule, or may serve as superagonists of an endogenous neurotrophic factor, thereby enabling an increased biological response at lower doses. Nucleic acids and plasmids encoding the chimeras are disclosed.

    摘要: Modified retroviral vector particles and modified retroviral producer cells producing such particles are provided for facilitating gene therapy procedures involving the transduction of target cells with retroviral vector particles in the presence of complement containing body fluids. The modifications involve genetic alterations to effect the expression by these cells and particles of complement inhibitor activity. The genetic alterations involve the introduction of nucleic acid expression constructs directing the expression of retroviral SU(gp70)/complement inhibitor chimeric proteins into cells from which the producer cells are derived.

    摘要: Methods and compositions are provided for facilitating gene therapy procedures involving the transduction of target cells with retroviral vector particles in the presence of complement containing body fluids. The administration of soluble complement inhibitor molecules to body fluids prevents the complement mediated inactivation of the retroviral vector particles, and provides a safety mechanism for such gene therapy procedures, as the action of soluble complement inhibitors is transient, and any retroviral vector particles present after the return of uninhibited complement activity will be inactivated. Preferred soluble complement inhibitors for use in the practice of the present invention include complement inhibitory anti-complement component mAbs (including complement inhibitory anti C5 antibodies).
