IPEX (Immune dysregulation Polyendocinopathy X linked) syndrome is a primary immunodeficience caused by mutations in the gene encoding the transcription factor forkhead box P3 (FOXP3), which leads to the loss of function of thymus-derived CD4+CD25+ regulatory T (tTreg) cells. Preclinical and clinical studies suggest that T cell gene therapy approaches designed to selectively restore the repertoire of Treg cells by transfer of wild type FOXP3 gene is a promising potential cure for IPEX. However, there is still a need for a vector that can be used efficiently for the preparation of said Treg cells. The inventors thus compared 6 different lentiviral constructs according to 4 criteria (vector titers, level of transduction of human CD4+ T cells, level of expression of FOXP3 and ΔLNGFR genes, degree of correlation between both expression) and selected one construct comprising a bidirectional EFS-PGK promoter that showed remarkable efficiency.

Described herein are compositions and methods for treating a patient having or at risk of developing a neurocognitive disorder, such as Alzheimer's disease, Parkinson's disease, and/or a frontotemporal lobar dementia. Using the compositions and methods of the disclosure, a patient, such as an adult human patient, may be provided one or more agents that elevate the expression and/or activity levels of a protein or series of proteins whose deficiency is associated with the corresponding disease. Exemplary agents that may be used in conjunction with the compositions and methods of the disclosure for this purpose include cells, such as cells, that contain nucleic acids encoding the protein or proteins of interest, as well as vectors, such as viral vectors, encoding the protein or proteins of interest. Additional examples of such agents include the protein or proteins themselves, as well as interfering RNA molecules that stimulate their endogenous expression.

In certain embodiments a lentiviral vector having optimized reduced size LCR with improved enhancer activity is provided. In certain embodiments direct treatment of a subject by direct introduction of the vector(s) described herein is contemplated. The lentiviral compositions may be formulated for delivery by any available route including, but not limited to parenteral (e.g., intravenous), intradermal, subcutaneous, oral (e.g., inhalation), transdermal (topical), transmucosal, rectal, and vaginal.

The present invention provides an adeno-associated virus (AAV) vector gene therapy for use in treating a monogenic form of nephrotic syndrome, wherein the AAV vector comprises a NS-associated transgene and minimal nephrin promoter NPHS1 or podocin promoter NPHS2.

The presently disclosed subject matter provides for expression cassettes that allow for expression of a globin gene or a functional portion thereof, vectors comprising thereof, and cells transduced with such expression cassettes and vectors. The presently disclosed subject matter further provides methods for treating a hemoglobinopathy in a subject comprising administering an effective amount of such transduced cells to the subject.

The present disclosure provides nucleic acid expression cassettes, vectors, compositions and methods for the treatment of ATPase-mediated diseases in a subject.

Provided are compositions and methods for inducing expression of human beta-globin in erythrocytes for use in prophylaxis and/or therapy of a hemoglobinopathy in an individual. The method generally entails introducing into CD34+ cells a poly-nucleotide encoding: i) a 5′ long terminal repeat (LTR) and a self-inactivating 3′ LTR; ii) at least one polyadenylation signal; iii) at least one promoter; iv) a globin gene locus control region (LCR); v) an ankyrin insulator element (Ank); vi) a Woodchuck Post-Regulatory Element (WPRE) configured such that the WPRE does not integrate into a target genome; and vii) a sequence that is a reverse complement of a sequence encoding human beta-globin, and can include beta-globin that has a PT87Q mutation. Intron 2 of the beta globin gene can be a complete intron. Modified erythrocyte progenitor cells, recombinant vectors and virions comprising recombinant polynucleotides, and methods of making the vectors and virions are included.

The present disclosure provides recombinant expression vectors expressing a novel neutralizing antibodies against SARS-COV-2, or the antigen binding fragments thereof. Pharmaceutical composition and kits comprising the same, and the uses thereof are also provided.

Aspects of the disclosure relate to compositions and methods for treating hereditary hearing loss and/or vision loss, for example, due to Usher syndrome, Type 3A. In some embodiments, the disclosure provides a recombinant adeno-associated virus comprising: (i) an AAV-S capsid protein, and (ii) an isolated nucleic acid comprising a transgene (e.g., a transgene for expressing a clarin-1 protein). The present disclosure also provides methods of treating hereditary hearing loss and/or vision loss (e.g., Usher Syndrome, Type 3A) using the same.
