  • Publication number: 20060073119
    Abstract: Vectors and methods are provided for treatment of neurodegenerative disorders by administration of anti-inflammatory cytokines, such as IL-10. Anti-inflammatory cytokines can be administered as a protein or by gene therapy, using plasmid delivery or a viral vector such as adeno-associated virus (AAV). Diseases including Parkinson's disease, Amyotrophic Lateral Sclerosis, Alzheimer's disease and Multiple Sclerosis may be treated using the vectors and methods of the invention.

  • Publication number: 20060035364
    Abstract: Compositions and methods are provided for preparation of concentrated stock solutions of AAV virions without aggregation. Formulations for AAV preparation and storage are high ionic strength solutions (e.g. ?˜500 mM) that are nonetheless isotonic with the intended target tissue. This combination of high ionic strength and modest osmolarity is achieved using salts of high valency, such as sodium citrate. AAV stock solutions up to 6.4×1013 vg/mL are possible using the formulations of the invention, with no aggregation being observed even after ten freeze-thaw cycles. The surfactant Pluronic® F68 may be added at 0.001% to prevent losses of virions to surfaces during handling. Virion preparations can also be treated with nucleases to eliminate small nucleic acid strands on virions surfaces that exacerbate aggregation.

  • Publication number: 20050282771
    Abstract: Methods for treating bleeding disorders using non-anticoagulant sulfated polysaccharides (NASPs) as procoagulants are disclosed. NASPs can be administered as single agents, or in combination with one another, or with other medications (such as factors VII, VIII and IX) to promote hemostasis. In particular, the use of NASPs in treatment of bleeding disorders, including congenital coagulation disorders, acquired coagulation disorders, and trauma induced hemorrhagic conditions is described.

  • Patent number: 6897063
    Abstract: Accessory functions capable of supporting efficient recombinant AAV (rAAV) virion production in a suitable host cell are provided. The accessory functions are in the form of one or more vectors that are capable of being transferred between cells. Methods of producing rAAV virions are also provided. The methods can be practiced to produce commercially significant levels of rAAV particles without also generating significant levels of infectious helper virus or other contaminating by-products.
