Abstract: The invention relates to sulfamidase (SGSH) and SGSH variants. SGSH and SGSH variants can be delivered by way of a recombinant adeno-associated virus (rAAV) particle to a mammal's central nervous system (CNS) to transduce CNS cells that contact cerebrospinal fluid (CSF). Target mammals for SGSH and SGSH variant administration include mammals with a deficiency or defect in SGSH expression or function.

Abstract: Provided herein are systems for increasing AAV particle production. These systems comprise producer cell lines adapted for the production of AAV particles, as well as methods of producing AAV particles using said producer cell lines. Also provided are AAV particles produced by said production systems, producer cell lines and methods.

Abstract: Provided herein are chimeric minigenes, where the alternative splicing of the minigene determines whether an encoded gene is expressed. In particular, the minigenes are alternatively spliced in response to splicing modulator dmgs, such that the encoded gene is only expressed in the present of the splicing modulator dmg. The encoded gene may encode an inhibitory RNA, a CRISPR-Cas9 protein, a transactivator, or a therapeutic protein.

Abstract: Compositions and methods are provided for the inhibition, treatment and/or prevention of Huntington's disease and related disorders.

Abstract: The present disclosure provides methods for treating or preventing Huntington's disease (HD) in a subject in need thereof, comprising administering a therapeutic agent that activates mTORC 1 function and/or increases Ras Homolog Enriched in Striatum (Rhes) level in the subject's brain as compared to the function or level in the subject prior to treatment, and methods for modulating mHTT-associated metabolic phenotypes and/or reversal of striatal atrophy by administering a therapeutic agent that activates mTORC1 function and/or increases Ras Homolog Enriched in Striatum (Rhes) level in the subject's brain as compared to the function or level in the subject prior to treatment.

Abstract: Compositions and methods are provided for the inhibition, treatment and/or prevention of fragile X syndrome and related disorders.

Abstract: Compositions and methods are provided for the inhibition, treatment and/or prevention of Huntington's disease and related disorders.

Abstract: Provided herein are nucleic acids that comprise both an expression cassette for a therapeutic protein (e.g., Ataxin-1-like) and an expression cassette for a therapeutic inhibitory RNA (e.g., a miRNA that targets ataxin-1 mRNA). In some instances, the expression cassette for the therapeutic inhibitor RNA lies within an intron of the expression cassette for the therapeutic protein. Also provided are methods of using the nucleic acids to treat spinocerebellar.

Abstract: Provided herein are chimeric transactivator minigenes, where the alternative splicing of the minigene determines whether a transactivator is expressed. Expression of the transactivator results in the transcription of a target gene that is under the control of a designer promoter sequence. Alternatively, provided herein are chimeric target gene minigenes, wherein the alternative splicing of the minigene directly determines whether the target gene is expressed. The target gene may encode an inhibitory RNA, a CRISPR-Cas9 protein, or a therapeutic protein.

Abstract: The present disclosure provides filler or stuffer sequences, compositions thereof including expression cassettes and vectors, such as viral (e.g., AAV) vectors and methods of delivering a therapeutic agent to a mammal and/or treating a disease.

Abstract: The invention relates to sulfamidase (SGSH) and SGSH variants. SGSH and SGSH variants can be delivered by way of a recombinant adeno-associated virus (rAAV) particle to a mammal's central nervous system (CNS) to transduce CNS cells that contact cerebrospinal fluid (CSF). Target mammals for SGSH and SGSH variant administration include mammals with a deficiency or defect in SGSH expression or function.

Abstract: The invention provides expression cassettes and vectors, such as viral (e.g., AAV) vectors, comprising a first nucleic acid encoding a nuclease defective Cas 9 (dCas9) polypeptide and a second nucleic acid encoding a guide polynucleotide that targets the dCas9 polypeptide to the transcriptional start site of an allele encoding a mutant huntingtin gene (HTT)-encoded protein. Also provided are pharmaceutical composition comprising the disclosed expression cassettes and vectors, as well as methods of inhibiting expression of a mutant HTT protein and of treating Huntington's Disease and symptoms associated with the disease.

Abstract: The present disclosure provides methods of treating a disease or delivering a therapeutic agent to a mammal comprising administering to the mammal's deep cerebella nuclei a recombinant adeno-associated virus (rAAV) particle comprising an AAV capsid protein and a vector comprising a nucleic acid encoding a therapeutic agent inserted between a pair of AAV inverted terminal repeats in a manner effective to infect the CNS cell of the non-rodent mammal such that the CNS cell expresses the therapeutic agent in the non-rodent mammal.

Abstract: The present disclosure provides methods of treating a disease or delivering a therapeutic agent to a mammal comprising administering to the mammal's cisterna magna and/or ventricle an rAAV particle containing a vector comprising a nucleic acid encoding a therapeutic protein inserted between a pair of AAV inverted terminal repeats in a manner such that cells with access to the cerebrospinal fluid (CSF) express the therapeutic agent and in certain embodiments secretes the therapeutic agent into the CSF for distribution to the brain.

Abstract: The present disclosure provides targeting peptides and vectors containing a sequence that encodes targetting peptides that deliver agents, to the eye. The present inventors have discovered peptides that function to target agents, such as viral vectors, to ocular cells. The present disclosure describes a method to utilize these novel peptides to direct, for example, viral capsids to the cell type of interest. In this instance, ocular cells (such as retinal cells) are targeted by the identified peptides. Vectors harboring capsid proteins modified to include such peptides can be used to provide therapeutic agents to the eye.

Abstract: The invention provides methods and uses for delivering progranulin to the central nervous system (CNS) of a mammal. Methods and uses include, for example, administering to a mammal a vector comprising a nucleic acid encoding progranulin, variant, derivative or functional fragment thereof to the mammal's brain ventricle to transduce CNS cells and/or cells that contact the cerebrospinal fluid (CSF) of the mammal such that the cells express the progranulin, variant, derivative or functional fragment thereof.

Abstract: Provided are methods of treating a lysosomal storage disorder in a mammal which method includes administering AAV particles encoding a polypeptide to the central nervous system of the mammal. AAV particles may be delivered by direct injection into the brain, spinal cord, cerebral spinal fluid or a portion thereof for expression.
