A pharmaceutical composition comprising an immunoparticle is provided. The pharmaceutical composition comprising a monoclonal secondary antibody immunocomplexed with a primary antibody, wherein said monoclonal secondary antibody is coupled on an outer surface of a particle and wherein said particle is loaded with a pharmaceutical agent.

Methods and compositions for the production of phospholipid-ligand bioconjugates and uniform targeted microbubbles are provided. These methods and compositions find use in ultrasound and molecular imaging applications related to cancer and other diseases. The methods of the present disclosure comprise contacting a phospholipid comprising a maleimide containing functional group with a ligand comprising a C terminal cysteine residue. The methods disclosed herein solves the problems in producing ready-to-use and clinically translatable ultrasound molecular imaging agents by incorporating small protein ligands engineered to bind against biomarkers representing pathological angiogenesis or abnormal cells. The methods also overcome the current limitations in producing uniformly targeted microbubbles in a scalable, economical and reproducible manner.

Compositions and methods for therapeutic delivery are disclosed. More particularly, the present disclosure relates to nanoparticle compositions that sequester the activity of a target molecule while leaving other domains accessible to bind targeted tissues of interest. Methods for thrombus dissolution include administering a nanoparticle reversibly coupled to a target molecule that can dissolve a blood clot. Compositions and methods for inducing blood clotting are also disclosed. Methods for inducing blood clotting include administering a nanoparticle reversibly coupled to a target molecule that can induce the formation of a blood clot. Methods for sequestering a target molecule are also disclosed. The method includes reversibly coupling a target molecule to a nanoparticle having an affinity ligand that reversibly couples the target molecule, and thus, sequesters the target molecule activity until the target molecule interacts with its substrate resulting in the release of the target molecule.

The invention creates engineered surface protein expression on vesicles for specific targeting and delivery of agents to autophagic and apoptotic cells. Moreover, the vesicles of the invention can achieve a synergistic effect on the targeting and drug delivery to autophagic and apoptotic cells and autophagic and apoptotic cells-containing tissues.

Disclosed is a nanocarrier-containing immunosuppressive agent that is targeted to C3 breakdown products, integrin, or a combination thereof, to reduce the deleterious systemic effects of the immunosuppressive agent. Also disclosed is a method for suppressing an allo-immune response in a subject, such as one that can occur after an allograft transplantation.

Application for MDR TNBC significantly increasing the efficacy of TNBC treatment and address a global health concern by blocking the ability of mitochondria to fuse together and with other organelles through a nanomedicine therapy. The development of a dual targeted nanomedicine therapy targeting the epidermal growth factor receptor on the surface of TNBC cancers cells and subcellular targeting of mitochondria through mitofusin 2 (MFN2) targeting (mitofusin mediates inter-mitochondrial fusion and fusion of mitochondria with the endoplasmic reticulum). The combination therapy delivers an MFN2-peptidepolymer construct for blocking MFN2 along with a low dose of BAM? (a BAX activator). Transient blocking of MFN2 reduces cellular energy capacity (through decreased mitochondrial fusion), decrease total protein production (by decreased mitochondrial coupling to the endoplasmic reticulum), increases the susceptibility of the cell to paclitaxel or BAM? (increased efficacy of lower dose), with minimal toxicity to normal cells (as IVIFN2 blocking inhibits mitochondrial fusion not mitochondrial function).

Provided herein are polymer materials that find use in, for example, delivery of short-chain fatty acids. In particular, polymers are provided that form stable nanoscale structures and release their payload, for example, by cleavage of a covalent bond (e.g., via hydrolysis or enzymatic cleavage). The polymers are useful, for example, for delivery of payloads (e.g., SCFAs) to the intestine for applications in health and treatment of disease, and have broad applicability in diseases linked to changes in the human microbiota including inflammatory, autoimmune, allergic, metabolic, and central nervous system diseases, among others.

A pharmaceutical composition comprising an immunoparticle is provided. The pharmaceutical composition comprising a monoclonal secondary antibody immunocomplexed with a primary antibody, wherein said monoclonal secondary antibody is coupled on an outer surface of a particle and wherein said particle is loaded with a pharmaceutical agent.

The present invention is directed to targeted micelle active agent carriers. The carriers suitably include micelle forming components, along with pH sensitive molecules, and targeting moieties. They are useful in the treatment of various brain cancers.

The present invention relates to lipid nanoparticles for in vivo drug delivery and uses thereof, and the lipid nanoparticle are liver tissue-specific, have excellent biocompatibility and can deliver a gene therapeutic agent with high efficiency, and thus it can be usefully used in related technical fields such as lipid nanoparticle mediated gene therapy.
