  • Publication number: 20240167008
    Abstract: The present invention provides novel systems, methods and compositions for making and using recombinantly engineered novel Cas9 enzymes optimized for human cells, for nucleic acid targeting and manipulation. The present invention is based on the discovery of novel Cas9 enzymes from Streptococcus constellatus, Sharpen spp. isolate RUG017, Veillonella parvula, Ezakiella peruensis, Lactobacillus fermentum strain AF15-40LB strain and Peptoniphilus sp. Marseille-P3761 bacteria that were codon-optimized and recombinantly produced for use in human cells. In some embodiments, novel Cas9 enzymes can be used for base editing. In some embodiments, the novel engineered Cas9 enzymes are used to treat human diseases.

  • Patent number: 11844825
    Abstract: Disclosed are methods and compositions for determining immunodominant peptides of target enzymes used in enzyme replacement therapy for lysosomal storage disorders. More specifically disclosed are immunodominant peptides for N-acetylgalactosamine-6-sulfatase (GALNS). Also disclosed are methods of inducing oral tolerance towards a target enzyme through oral administration of immunodominant peptides prior to commencing enzyme replacement therapy. More specifically disclosed is a method of inducing oral tolerance for GALNS, by orally administering specific immunodominant peptides for GALNS; in subjects suffering from mucopolysaccharidosis type IVA prior to commencing enzyme replacement therapy using GALNS.

  • Publication number: 20230340456
    Abstract: The present disclosure is directed to methods of producing a modified nucleic acid comprising a precise deletion in a target nucleic acid in a cell comprising generating, within the cell, a first single strand break on a first strand of the target nucleic acid and a second single strand break on a second strand of the target nucleic acid, thereby forming a double strand break in the target nucleic acid having a first 3? overhang and a second 3? overhang; processing the first 3? overhang and the second 3? overhang with an exonuclease molecule, thereby deleting the segment of the target nucleic acid that was located between the first single strand break and the second single strand break, and forming a processed double strand break; and allowing the processed double strand break to be repaired by at least one DNA repair pathway, thereby producing the modified nucleic acid comprising the precise deletion in the target nucleic acid in the cell.
