Compositions and methods of use thereof for delivering nucleic acid cargo into cells are provided. The compositions typically include (a) a 3E10 monoclonal antibody or an antigen binding, cell-penetrating fragment thereof; a monovalent, divalent, or multivalent single chain variable fragment (scFv); or a diabody; or humanized form or variant thereof, and (b) a nucleic acid cargo including, for example, a nucleic acid encoding a polypeptide, a functional nucleic acid, a nucleic acid encoding a functional nucleic acid, or a combination thereof. Elements (a) and (b) are typically non-covalently linked to form a complex.

Chitosan-nucleic acid polyplex compositions containing a reversibly bound polymer coat comprising linear block copolymers with a polyanionic anchor region and at least one polyethylene glycol tail region are described herein. In some cases, the compositions exhibit improved stability and/or mucosal diffusion as compared to uncoated particles. In some cases, the reversibly bound polymer coat does not interfere with, or enhances, transfection of target cells or tissues as compared to uncoated particles.

The present invention relates to a Factor VIII (FVIII) polypeptide, a polynucleotide comprising a Factor VIII nucleotide sequence, and a recombinant AAV construct. The invention further relates to an AAV viral particle comprising the recombinant AAV construct of the invention, and a composition comprising the Factor VIII polypeptide, polynucleotide, recombinant AAV construct or AAV viral particle of the invention. The invention also relates to methods of using, and uses of, the Factor VIII polypeptide, polynucleotide, recombinant AAV construct, AAV viral particle and/or composition of the invention. The invention also relates to uses of the recombinant AAV construct of the invention for the production of AAV viral particles, and methods for producing AAV viral particles using the recombinant AAV constructs of the invention.

Provided is herein are extracellular vesicles (EVs) comprising a lipid bilayer comprising one or more immunosuppressive molecules. Also provided herein are methods to induce tolerance to a therapeutic agent such as AAV, using the EVs described herein.

The present invention relates to a double-stranded oligonucleotide capable of inhibiting amphiregulin expression in a very specific and highly efficient manner, preferably a double-stranded oligonucleotide comprising a sequence in the form of an RNA/RNA, DNA/DNA or DNA/RNA hybrid, and the use of a double-stranded oligonucleotide structure, which comprises the double-stranded oligonucleotide, and nanoparticles, for preventing or treating obesity.

The present invention relates to RNA containing compositions for use in the treatment or prophylaxis of tumor and/or cancer diseases, to a pharmaceutical composition, to a kit and to uses of the RNA containing compositions for the treatment or prophylaxis of tumor and/or cancer diseases.

The present invention provides novel, stable lipid particles comprising one or more active agents or therapeutic agents, methods of making the lipid particles, and methods of delivering and/or administering the lipid particles. More particularly, the present invention provides stable nucleic acid-lipid particles (SNALP) comprising a nucleic acid (such as one or more interfering RNA), methods of making the SNALP, and methods of delivering and/or administering the SNALP.

This disclosure relates to the field of RNA to prevent or treat coronavirus infection. In particular, the present disclosure relates to methods and agents for vaccination against coronavirus infection and inducing effective coronavirus antigen-specific immune responses such as antibody and/or T cell responses. Specifically, in one embodiment, the present disclosure relates to methods comprising administering to a subject RNA encoding a peptide or protein comprising an epitope of SARS-CoV-2 spike protein (S protein) for inducing an immune response against coronavirus S protein, in particular S protein of SARS-CoV-2, in the subject, i.e., vaccine RNA encoding vaccine antigen.

The present invention provides Factor VIII polypeptides which comprise one or more substitution mutations compared to a corresponding wild-type Factor VIII, wherein the one or more substitution mutations are located at an inter-domain interface between two domains of the Factor VIII polypeptide. Also provided are polynucleotides comprising a Factor VIII nucleotide sequence encoding a Factor VIII polypeptide of the invention, recombinant AAV constructs comprising such polynucleotides, AAV viral particles comprising such recombinant AAV constructs, compositions comprising the Factor VIII polypeptide, polynucleotide, recombinant AAV construct, or AAV viral particle of the invention, and the use of the Factor VIII polypeptides, polynucleotides, recombinant AAV constructs, AAV viral particles and compositions of the invention in therapy.

The present invention provides, in part, a biodegradable compound of formula I, and sub-formulas thereof:Formula (I) or a pharmaceutically acceptable salt thereof, where each X independently is O or S, each Y independently is O or S, and each R.sup.1 independently is defined herein; and a liposome composition comprising the cationic lipid of formula I or a sub-formula thereof, and methods of delivering agents, such as nucleic acids including mRNA, in vivo, by administering to a subject the liposome comprising the cationic lipid of formula I or a sub-formula thereof, where the agent is encapsulated within the liposome. ##STR00001##
