The present disclosure includes the use of a miRNA inhibitor for treating a disease or condition associated with a decreased level of SIRT1, PGC-1α, CD36, LRRK2, NRG1, STMN2, VLDLR, NRXN1, GRIA4, NXPH1, PSD-95, and/or synaptophysin protein or SIRT1, PGC-1α, CD36, LRRK2, NRG1, STMN2, VLDLR, NRXN1, GRIA4, NXPH1, PSD-95, and/or synaptophysin gene expression. In some aspects, the miRNA inhibitor can be used to treat a disease or condition associated with an increased level of caspase-3 protein or gene expression. The miRNA inhibitor useful for the present disclosure can inhibit miR-485 expression and/or activity, which in turn can increase the level of SIRT1, PGC-1α, CD36, LRRK2, NRG1, STMN2, VLDLR, NRXN1, GRIA4, NXPH1, PSD-95, and/or synaptophysin protein or gene expression; and/or can decrease the level of caspase 3 protein or gene expression.

The present invention relates to conjugates of π-electron-pair-donating heteroaromatic nitrogen-comprising drugs and pharmaceutically acceptable salts thereof, pharmaceutical compositions comprising said conjugates and the use of said conjugates as medicaments.

The present disclosure relates to the use of PGC-1α expression to identify a subject that is conducive to treatment with a ma-485 inhibitor. In some aspects, the subject suffers from a disease or disorder associated with reduced PGC-1α expression. In some aspects, the PGC-1α expression is measured in the serum of the subject.

The present disclosure relates to the use of SIRT1 expression to identify a subject that is conducive to treatment with a miR-485 inhibitor. In some aspects, the subject suffers from a disease or disorder associated with reduced SIRT1 expression. In some aspects, the SIRT1 expression is measured in the serum of the subject.

The present invention relates to proteins suitable for being used as scaffolds to which a peptide of interest is bound, or which are comprised within a conjugate to which an agent of interest is attached. It also relates to said conjugates suitable for the selective delivery of their conjugated agents of interest to specific cell and tissue types, wherein said agent 5 can be a therapeutic agent or an imaging agent. It also relates to nanoparticles comprising such conjugates and the therapeutic uses thereof.

The present disclosure relates to complexes and compositions of cationic compounds combined with low mass percentages of PEGylated compounds, such as PEGylated lipids, for the delivery of nucleic acids and other polyanionic cargoes to cells, methods for preparing complexes and compositions comprising one or more cationic compounds and a low mass percentage of PEGylated compounds with polyanionic compounds, and methods for delivering the polyanionic compounds to cells.

Improved pharmaceutical nanoparticle compositions and improved methods for preparing the compositions comprising histidine-lysine copolymers and an acetate salt or phosphate anion are provided. The addition of acetate or phosphate anion to the histidine-lysine copolymer prior to mixing with a nucleic acid alters nanoparticle size and polydispersity index of the compositions and provides a more uniform particle size distribution.

The present invention serves as a platform technology to deliver RNA therapeutics into cells. It provides a system for delivery of RNA molecules for biomedical purposes. The modular protein-based system described in this invention allows for customization of protein modules to achieve specificity in cell-targeting, thus having the ability to be optimized for treating different diseases. Examples of types of diseases that could adopt this technology for treatment include cancer, neurodegenerative diseases and viral infection.

The present invention relates to polymeric nanoparticles comprising a cytokine or a nucleic acid encoding for a cytokine, pharma-ceutical compositions comprising the same, and methods for treating certain diseases comprising administering these polymeric nanoparticles to a subject in need thereof.

The present disclosure pertains to the technical field of immunotherapy or disease prevention and treatment with vaccines, in particular to a heterocyclic compound containing two or more sulfur atoms and an application thereof in preparing a nano-vaccine. Provided is the application of the heterocyclic compound containing at least two sulfur atoms and capable of being covalently or non-covalently linked to a polypeptide in preparing the nano-vaccine. A nanoparticle prepared by self-assembly of the compound and an antigen can enter the dendritic cytoplasm in nonendocytic pathway, thereby improving the uptake efficiency of the antigen and an immune adjuvant. In the process of entering a cell, the nano-vaccine can effectively avoid or reduce biodegradation of the antigen or nucleic acid adjuvant caused by enzymes in lysosomes, and therefore the nano-vaccine can efficiently activate the dendritic cells and improve the cross-presentation of the antigen, thereby effectively activating CD8+ T cells and promoting T cell proliferation. Therefore, the nano-vaccine can prevent tumor cell proliferation and virus infection by efficient immune activation and immune regulation.
