Abstract: The invention relates to compositions and methods of treating cystic fibrosis. More specifically, this invention relates to the use the AAV vectors and constructs to provide gene therapy to cystic fibrosis patients.

Abstract: The subject invention concerns materials and methods for gene therapy. One aspect of the invention pertains to vectors which can be used to effect genetic therapy in animals or humans having genetic disorders where expression of high levels of a protein of interest are required to treat or correct the disorder. The subject invention also pertains to methods for treating animals or humans in need of gene therapy to treat or correct a genetic disorder. The materials and methods of the invention can be used to provide therapeutically effective levels of a protein that is non-functional, or that is absent or deficient in the animal or human to be treated. In one embodiment, the materials and methods can be used to treat alpha-1-antitrypsin deficiency.

Abstract: Disclosed are recombinant adeno-associated viral (rAAV) vector compositions that are expressed in selected mammalian cells, such as pancreatic islets cells, and that encode one or more mammalian serpin or cytokine polypeptides having therapeutic efficacy in the amelioration, treatment and/or prevention of interleukin deficiencies, such as for example diabetes, and related diseases of the pancreas. Also disclosed are methods and compositions for preventing diabetes in a mammal, reducing the rate of disease progression, and ameliorating the symptoms of diabetes in humans at risk for developing such conditions.

Abstract: Vectors that encode Adeno-Associated Virus (AAV) Rep and Cap proteins of different serotypes and Adenovirus transcription products that provide helper functions were used to produce pseudotyped recombinant AAV (rAAV) virions. Purification methods generated pseudotyped rAAV virion stocks that were 99% pure with titers of 1×1012–1×1013 vector genomes/ml.

Abstract: Phenylalanine hydroxylase deficiency in a subject is corrected by administering to the subject rAAV-based vectors that include a sequence encoding functional phenylalanine hydroxylase. Ribozymes are used to reduce expression of defective phenylalanine hydroxylase in a cell.

Abstract: Recombinant adeno-associated virus (rAAV) virions having a serotype 1 capsid protein are effective for transferring heterologous nucleic acids into DC.

Abstract: Adeno-associated virus (AAV) vectors may have utility for gene therapy but heretofore a significant obstacle has been the inability to generate sufficient quantifies of such recombinant vectors in amounts that would be clinically useful for human gene therapy application. Stable, helper-free AAV packaging cell lines have been elusive, mainly due to the activities of Rep protein, which down-regulates its own expression and reverses cellular immortalization. This invention provides packaging systems and processes for packaging AAV vectors that efficiently circumvent these problems by replacing the AAV p5 promoter with a heterologous promoter and that allow for substantially increased packaging efficiency.
