The present invention relates to compositions for the delivery of molecules such as a peptide, a nucleic acid and/or a small molecule drug. In particular, the present invention relates to an extracellular vesicle (EV) loaded with a peptide, a nucleic acid and/or a small molecule drug, along with methods of producing said EV.

C-to-G Transversion DNA Base Editors

Engineered transversion base editors that enable expanded amino acid modifications and methods of using the same. Described herein, for example, are fusion proteins containing cytidine deaminases (e.g. human or rat APOBECs, pmCDA1 or AID) or adenosine deaminases (e.g. E. coli TadAs) or a combination thereof, catalytically impaired CRISPR-Cas proteins (e.g. Cas9, CasX or Cas12 nucleases), linkers, nuclear localization signals (NLSs) and a human or E. coli uracil-n-glycosylase (UNG) and/or REV1 protein that enable the CRISPR-guided programmable introduction of C-to-G and G-to-C transversions in DNA. The UNG may be fused to the deaminase-Cas fusion or not, in which case endogenous UNG may be recruited using molecular machinery that is integrated into the deaminase-Cas fusion architecture, e.g. using peptide or RNA aptamers or scFVs, sdABs or Fabs.

Genomic engineering of biosynthetic pathways leading to increased NADPH

The disclosure relates to host cells having altered NADPH availability, allowing for increased production of compounds produced using NADPH, and methods of use thereof. NADPH availability is altered by one or more of: expressing an altered GAPDH, expressing a variant glutamate dehydrogenase (gdh), aspartate semialdehyde dehydrogenase (asd), dihydropicolinate reductase (dapB), and meso-diaminopimelate dehydrogenase (ddh), expressing a novel nicotinamide nucleotide transhydrogenase, expressing a novel threonine aldolase, and expressing or modulating the expression of a pyruvate carboxylase in the host cells.

Nanoparticle-attached enzyme cascades for accelerated multistep biocatalysis

A nanoparticle (for example, quantum dot) serves as a substrate for immobilizing enzymes involved in consecutive reactions as a cascade. This results in a significant increase in the rate of catalysis as well as final product yield compared to non-immobilized enzymes.

Gold optimized CAR t-cells

Control Devices are disclosed including RNA destabilizing elements (RDE), RNA control devices, and destabilizing elements (DE) combined with Chimeric Antigen Receptors (CARs) or other transgenes in eukaryotic cells. Multicistronic vectors are also disclosed for use in engineering host eukaryotic cells with the CARs and transgenes under the control of the control devices. These control devices can be used to optimize expression of CARs in the eukaryotic cells so that, for example, effector function is optimized. CARs and transgene payloads can also be engineered into eukaryotic cells so that the transgene payload is expressed and delivered after stimulation of the CAR on the eukaryotic cell.

METHOD FOR DETECTING TARGET NUCLEIC ACID, METHOD FOR DETECTING NUCLEIC ACID-BINDING MOLECULE, AND METHOD FOR EVALUATING NUCLEIC ACID-BINDING ABILITY
20230031001 · 2023-02-02 ·

The present invention provides a method for detecting a target nucleic acid that discriminates the target nucleic acid from a non-target nucleic acid having a nucleotide sequence or modification state that differs from a portion of the target nucleic acid, the method comprising conducting a nucleic acid amplification reaction using a region in the non-target nucleic acid that differs from the target nucleic acid as a target region, using a region in the target nucleic acid that differs from the non-target nucleic acid as a corresponding target region, using a nucleic acid test sample as a template, and using a primer that hybridizes with both the target nucleic acid and the non-target nucleic acid, with the nucleic acid amplification reaction conducted in the presence of a molecule capable of binding specifically to the target region in the non-target nucleic acid, under temperature conditions under which the molecule can bind to the non-target nucleic acid, and then detecting the target nucleic acid on the basis of the presence or absence of an amplification product.

GENETICALLY OPTIMISED MICROORGANISM FOR PRODUCING MOLECULES OF INTEREST
20220348897 · 2022-11-03 ·

The invention concerns a genetically modified microorganism expressing a functional type I or II RuBisCO enzyme and a functional phosphoribulokinase (PRK), and in which the glycolysis pathway is at least partially inhibited, said microorganism being genetically modified so as to produce an exogenous molecule and/or to overproduce an endogenous molecule. According to the invention, the oxidative branch of the pentose phosphate pathway may also be at least partially inhibited. The invention also concerns the use of such a genetically modified microorganism for the production or overproduction of a molecule of interest and processes for the synthesis or bioconversion of molecules of interest.

METHOD FOR PRODUCING L-AMINO ACIDS USING MICROORGANISM CONTAINING NADP-DEPENDENT GLYCERALDEHYDE-3-PHOSPHATE DEHYDROGENASE

The present disclosure relates to a microorganism of the genus Corynebacterium having an increased L-amino acid producing ability, containing NADP-dependent glyceraldehyde-3-phosphate dehydrogenase derived from the genus Lactobacillus. According to the present disclosure, the NADP-dependent glyceraldehyde-3-phosphate dehydrogenase derived from Lactobacillus delbrueckii subsp. bulgaricus is introduced to increase the reducing power through the activity of NADP-dependent glyceraldehyde-3-phosphate dehydrogenase, thereby increasing the L-amino acid producing ability of the strains belonging to the genus Corynebacterium.

CHIMERIC RECOMBINANT PROTEIN ENCODING EPITOPES WITH IDENTITY TO BACTERIAL, FUNGAL, PARASITE AND HUMAN METABOLIC ENZYMES INVOLVED IN PATHOGENESIS DURING SEXUALLY TRANSMITTED INFECTIONS

Disclosed herein are compositions and methods for detecting antibodies directed to epitopes of the metabolic enzymes, fructose-1,6-bisphosphate aldolase (A), α-enolase (E), and glyceraldehyde-3-phosphate dehydrogenase (G), that are shared between T. vaginalis and human AEG proteins.

VACCINE FOR IMMUNOCOMPROMISED HOSTS

The invention provides peptides derived from a ubiquitous protein, and nucleic acids encoding such peptides. The invention extends to various uses of these peptides and nucleic acids, for example, as antigens for use in vaccines per se and in the generation of antibodies for use in therapeutic drugs for the prevention, amelioration or treatment of infections caused by sepsis-inducing bacteria. The invention particularly benefits immunocompromised hosts such as neonates, babies, children, women of fertile age, pregnant women, foetuses, the elderly and diabetics.
