The present disclosure relates to a mammalian cell line for producing adeno-associated virus (AAV), suitably including nucleic acids encoding helper genes and AAV genes, under the control of derepressible promoters. The disclosure also relates to isolated nucleic acid molecules that encode such genes, as well as methods of using the mammalian cells for producing AAVs.

A rAAV vector is described herein which has an AAVhu68 capsid and at least one expression cassette in the capsid. The at least one expression cassette comprises nucleic acid sequences encoding a functional SMN protein and expression control sequences that direct expression of the SMN sequences in a host cell. Also provided are compositions containing this rAAVhu68.SMN vector and methods of using same for spinal muscular atrophy in a patient.

The present invention relates to Adeno-associated virus type 9 methods and materials useful for intrathecal delivery of polynucleotides. Use of the methods and materials is indicated, for example, for treatment of lower motor neuron diseases such as SMA and ALS as well as Pompe disease and lysosomal storage disorders. It is disclosed that administration of a non-ionic, low-os-molar contrast agent, together with a rAA9 vector for the expression of Survival Motor Neuron protein, improves the survival of SMN mutant mice as compared to the administration of the expression vector alone.

A two-step chromatography purification scheme is described which selectively captures and isolates the genome-containing rAAV vector particles from the clarified, concentrated supernatant of a rAAV production cell culture. The process utilizes an affinity capture method performed at a high salt concentration followed by an anion exchange resin method performed at high pH to provide rAAV vector particles which are substantially free of rAAV intermediates.

Described herein are polynucleotide constructs and stable cell lines for inducible production of rAAV virions within which are packaged a payload polynucleotide.

The present disclosure is in the field of diagnostics and therapeutics for Alzheimer's Disease.

The invention provides for recombinant AAV vectors comprising a miniaturized human micro-dystrophin gene and methods of using the recombinant vectors to reduce or prevent fibrosis in subjects suffering from muscular dystrophy.
