A method for in utero and postnatal genome editing of a lysosomal storage disease gene, the method comprising administering to a subject an ABE or CBE complex, wherein the subject is an embryo, a fetus, a neonate, a child or an adult, ABE or CBE complex comprising CRISPR-mediated base editor and a guide RNA (gRNA), the gRNA targeting a mutation in a therapeutic gene; and introducing a modified codon in the therapeutic gene by base editing the therapeutic gene without inducing double strand DNA breaks, wherein the base editing is performed by the adenoviral vector, an adeno-associated viral vector, nucleoprotein complex or an mRNA in a lipid based nanoparticle.

Modified AAV vectors and uses thereof are provided.

The invention relates to novel adeno-associated virus (AAV) capsid proteins, AAV particles comprising a novel capsid protein, polynucleotides encoding these capsid proteins and AAV vectors expressing these capsid proteins. The invention also relates to methods of making the herein described AAV vectors expressing the novel capsid proteins of the invention and associated therapeutic uses of thereof.

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.

The invention relates to products and methods for transdifferentiating oligodendrocytes and/or oligodendrocyte precursor cells to neurons. The invention further relates to methods of treating central nervous system disorders and conditions.

The present invention relates to improved adeno-associated virus (AAV) particles for gene delivery and gene therapy. Provided are adeno associated virus (AAV) particles that comprise a modified capsid. The present invention further relates to methods for producing the improved AAV particles of this invention by removing natural binding sites in adeno associated virus (AAV) capsids and introducing ligand binding sites into said capsid to provide AAVs that transduce only particular cells of interest. An additional aspect of the present invention relates to modified AAV particles for use in the treatment of a disease and methods for treating a disease, comprising administering the modified AAV particles to a subject in need thereof. Yet a further aspect of this invention relates to the AAV particles of this invention for the transfection of cells, for example as a gene delivery tool in basic research.

The present disclosure relates to pharmaceutical compositions of adeno-associated viral (AAV) particles encoding siRNA molecules and methods for treating Huntington's Disease (HD).

A gene sequence of recombinant human type II mitochondrial dynein-like GTPase having a nucleotide sequence shown in SEQ ID NO: 1 and uses thereof. A fusion nucleic acid comprising a nucleic acid encoding human type II mitochondrial dynein-like GTPase. A recombinant expression vector comprising the nucleic acid or a fusion nucleic acid. A transformant by which the nucleic acid or the fusion nucleic acid is introduced into a host. A non-human mammalian ADOA model based on the inactivation of the gene of type II mitochondrial dynein-like GTPase, which can effectively improve the pathological manifestations of ADOA using a recombinant expression vector encoding the human type II mitochondrial dynein-like GTPase. The expression level of the nucleic acid encoding the human type II mitochondrial dynein-like GTPase is higher, therefore, more human type II mitochondrial dynein-like GTPase can be obtained in the mitochondria. which can better treat eye diseases such as ADOA.

Disclosed herein is a recombinant nucleic acid, comprising: a mitochondrial targeting sequence; a mitochondrial protein coding sequence, wherein said mitochondrial protein coding sequence encodes a polypeptide comprising a mitochondrial protein; and a 3′UTR nucleic acid sequence. Also disclosed is a pharmaceutical composition comprising the recombinant nucleic acid and a method of treating Leber's hereditary optic neuropathy (LHON) using the pharmaceutical composition.

The present invention relates to a modified and optimized sFlt1 nucleic acid for inclusion in a virus vector. Use of such vectors can be used for treatment of ocular disorders causing neovascularization, such as macular degeneration.
