Methods for treating IBD or an IBD related disorder in a subject in need thereof are provided that comprise combined intrathecal administration of a polynucleotide comprising a CLN1 open reading frame and intravenous administration of the polynucleotide. The polynucleotide comprising the CLN1 open reading frame is a wild-type CLN1 polynucleotide. In another aspect, the polynucleotide comprising the CLN1 open reading frame comprises codon-optimized polynucleotide sequence of the polynucleotide or its complement and is codon-optimized for expression in a human cell.

A spiral tube countercurrent chromatography rotor for separating virus in a two part aqueous solvent is described.

Provided are a complex that comprises a nucleic acid-containing nanoparticle and a hollow particle of a non-enveloped virus, a method for producing the complex, and a pharmaceutical composition comprising the complex.

The present invention relates to variant AAV capsid polypeptides, wherein the variant AAV capsid polypeptides exhibit increased transduction and/or tropism in human pancreatic tissue or human islets as compared non-variant parent capsid polypeptides.

Disclosed herein are packaging cell lines, in which adenovirus (Ad) E1A is constitutively expressed, that also contain integrated AAV rep and cap genes. The packaging cell lines exhibit little to no expressed Rep protein until helper virus function, such as adenovirus (Ad) E4, E2A and/or VA RNA are provided by, for example, transduction of the cells with a virus, vector or plasmid, such as an Ad-AAV hybrid virus. The promoter driving expression of AAV rep gene can be positioned far enough upstream (5′) of the rep coding sequence that E1A is unable to activate the promoter, activate substantial transcription of the rep gene and in turn produce Rep protein. Introduction of helper virus function, such as E2A, E4 and/or VA RNA into these packaging cells is able to drive AAV rep gene transcription, subsequent Rep protein expression and production of rAAV vector particles.

Described herein is an adeno-associated virus (AAV) capsid polypeptide bonded to a binding peptide including an amino acid sequence RGDX1X2X3X4, with X1 to X4 being independently selected amino acids, for use in treating and/or preventing a muscular disease and/or in muscle regeneration. Also described are polynucleotides, host cells, adeno-associated virus (AAV) capsids, pharmaceutical compositions, uses, and methods related to the AAV capsid polypeptide.

The invention provides modified adeno-associated virus (AAV) capsid proteins. Modified AAV capsid proteins include, for example, capsid proteins modified to have a peptide insertion comprising a nuclear localization signal (NLS) sequence, capsid proteins modified to have an amino acid substitution at an RXXL site or a (L/P)PXY site, where X can be any amino acid, and capsid proteins modified to have one or more particular amino acid positions substituted with a different amino acid.

Methods are described for predicting ancestral sequences for viruses or portions thereof. Also described are predicted ancestral sequences for adeno-associated virus (AAV) capsid polypeptides. The disclosure also provides methods of gene transfer and methods of vaccinating subjects by administering a target antigen operably linked to the AAV capsid polypeptides.

Described is hybrid viral vector comprising: a first virus such as bacteriophage T4; one or more second virus such as adeno-associated virus (AAV) attached to the first virus through cross-bridges, such as avidin-biotin cross-bridges; one or more DNA molecules packaged in the first virus; one or more nucleic acid molecules packaged in the second virus; and one or more proteins displayed on the surface of the first virus. Also described are methods of making and using such a hybrid viral vector.

The present disclosure provides materials and methods for treating a patient with one or more conditions associated with SOD1 whether ex vivo or in vivo. In addition, the present disclosure provides materials and methods for editing and/or modulating the expression of SOD1 gene in a cell by genome editing.
