Abstract: The present invention provides optimized nucleic acid molecules, methods for optimization of nucleic acid molecules and uses of optimized nucleic acid molecules. A modular design principle is provided that is suitable to generate a nucleic acid, particularly mRNA, which is tailored for a respective application. The nucleic acid molecules of the present invention can be obtained by the versatile combination of multiple modules on nucleic acid level. Such nucleic acid, e.g. mRNA, can be tailored by combining one or more modules, comprising (i) a nucleic acid moiety encoding a polypeptide of interest (e.g. a protein potentially producing a therapeutic outcome) and (ii) at least one further coding or non-coding nucleic acid moiety, e.g.

Abstract: The present invention is inter alia directed to compositions comprising at least one nucleic acid encoding at least one antigenic peptide or protein selected or derived from a Coronavirus membrane protein (M), nucleocapsid protein (N), non-structural protein, and/or accessory protein or an immunogenic fragment or immunogenic variant thereof. The composition may additionally comprise at least one nucleic acid encoding at least one antigenic peptide or protein selected or derived from a Coronavirus spike protein (S). The nucleic acid sequences of the compositions are preferably in association with a polymeric carrier, a polycationic protein or peptide, or a lipid nanoparticle (LNP). The compositions provided herein are for use in treatment or prophylaxis of an infection with at least one Coronavirus, and may therefore be comprised in a vaccine, preferably a multivalent vaccine.

Abstract: The present disclosure provides compositions and methods of use for Type V CRISPR/Cas proteins. Type V CRISPR/Cas nucleases may be configured to bind nucleic acids in a sequence specific manner. Such a binding event may activate the Type V CRISPR/Cas nuclease for sequence non-specific trans-collateral cleavage of single-stranded nucleic acids. Provided herein are methods leveraging Type V CRISPR/Cas nuclease trans-collateral cleavage for identifying nucleic acid sequences.
