Therapeutic methods and compositions for the in utero or postnatal treatment of diseases associated with alternative splicing are provided. Compositions of the disclosure include delivery nanoparticles with an inner region surrounded by a nucleic acid scaffolding that is, in turn, linked to therapeutic agents that promote healthy mRNA splicing phenotypes in fetal cells when the compositions are delivered to a fetus in utero or in a patient after birth. The nanoparticles preferably include targeting complexes or antibodies that promote endosomal uptake into such cells and escape peptides that release the nanoparticles from endosomes into the cytosol within the cells to allow the therapeutic agents to promote preferred splicing

Provided herein are erythrocytes with polymeric particles (i.e., ‘backpacks’) adhered that provide delivery of payload therapeutic agents to subjects administered these cells.

Disclosed are methods and related compositions for administering a high affinity IL-2 receptor agonist in combination with immunosuppressants. The methods and compositions provided can be used for enhancing regulatory T cells, including antigen-specific regulatory T cells.

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.

A drug carrier nanoparticle has been synthesized that can specifically target the proximal tubules of the kidneys. The nanoparticles accumulate in the kidneys to a greater extent than other organs (e.g., up to 3 or more times greater in the kidney than any other organ). They can encapsulate many classes of drug molecules. The nanoparticles are biodegradable and release the drug as they degrade. The particles can sustainably release a drug within the kidneys for up to two months. The nanoparticles are useful for the treatment of diseases that affect the proximal tubules, such as heart failure, liver cirrhosis, hypertension, and renal failure; the study of relative blood flow to the renal cortex and medulla; and delivery of agents to treat gout.

The presently disclosed subject matter provides nanoparticles comprising bortezomib encapsulated in a non-water-soluble polymer matrix in a form of a bortezomib-tannic acid complex; methods for preparing the nanoparticle; and use of the nanoparticles for treating liver cancer.

The present invention relates to the treatment of ocular diseases in a human subject In particular, the invention relates to an intracameral administration of a sustained release biodegradable intracameral implant.

Nanoparticles include a polymeric core and a high density lipoprotein (HDL) component where the ratio by weight of the HDL component to the polymeric core is in a range from about 1:9 to about 9:1, such as about 75:25 or less or about 7:3 or less. The nanoparticles may also include a mitochondria targeting moiety. The nanoparticles may be used to treat or prevent atherosclerosis or to maintain lipid homeostasis.

The present disclosure provides nanoparticle compositions comprising i) a polymeric nanoparticle, ii) one or more ligands conjugated to the polymeric nanoparticle, and iii) naloxone. The disclosure also provides methods and pharmaceutical compositions comprising the nanoparticle compositions for use in treating patients with various disease states.

Disclosed are peptides that specifically bind to neutrophils and uses thereof for neutrophil-targeted delivery of drugs or diagnostic agents in medical conditions including cancer as well as infectious, inflammatory and autoimmune diseases or disorders.
