Abstract: Provided herein are recombinant adeno-associated virus (rAAV) vectors comprising nucleic acid encoding N-acetyl-glucosamine-1-phosphate transferase, alpha and beta subunits (GNPTAB) and at least one AAV inverted terminal repeat (ITR). In some embodiments, the rAAV vectors may be included in a rAAV particle, which may be contained in pharmaceutical compositions and kits. These vectors, particles, compositions, and kits may find use, inter alia, in methods and uses related to treating mucolipidosis type II (ML II) or mucolipidosis type III (ML III) in a mammal, or related to increasing body size, bone mineral content, and/or bone mineral density in a mammal with mucolipidosis type II (ML II) or mucolipidosis type III (ML III).

Abstract: Sustained transgene expression will be required for the vast majority of genetic diseases being considered for gene therapy. The initially high levels of expression attained with plasmid DNA (pDNA) vectors containing viral promoters, such as that from cytomegalovirus (CMV), decline precipitously to near background levels within 2 to 3 weeks. We have constructed pDNA vectors containing the human cellular ubiquitin B (Ub) promoter and evaluated their expression in the mouse lung. Cationic lipid-pDNA complexes were instilled intranasally (IN) or injected intravenously (IV) into immunodeficient BALB/c mice. Chloramphenicol acetyltransferase (CAT) reporter gene expression from the Ub promoter was initially very low at day 2 post-administration but by day 35 exceeded the level of expression attained from a CMV promoter vector by 4- to 9-fold.

Abstract: The present invention relates to methods for treatment of systemic disorders using the lung as a depot organ for transgene delivery. Transfection of the pulmonary epithelium, particularly the deep alveolar cells, or pulmonary endothelial cells, is achieved via local administration of a transgene delivery vector to the lung. The transfected cells express the transgene, and the protein thereby expressed is communicated into the circulatory system. Once entering into the circulatory system, the protein is able to achieve a systemic therapeutic effect.

Abstract: A method of generating an anti-tumor immune response using a cationic molecule:biologically active molecule complex is provided. In one embodiment, the anti-tumor immune response is a protective, memory-based response. The complex may be administered alone, as the active ingredient in a formulation, or as an adjuvant. The invention also provides for methods of generating an immunostimulatory response against the tumor cell present during treatment by exposing a cationic molecule:biologically active molecule complex to a mammalian cell or a foreign tumor cell.
