For applications in drug delivery, “smart” materials have been designed to respond to conditions within microenvironments of tissues or cells. The present invention features stimuli-responsive cross-linked hydrogels that respond to specific metabolites of disease. For example, protein-polymer materials of the present invention are configured to release their drug cargo upon encountering the higher lactate concentrations within tumor microenvironments.

The disclosure relates to tropical diseases such as viral mosquito borne illnesses and the treatment thereof. The invention includes ribonucleic acid vaccines and combination vaccines, as well as methods of using the vaccines and compositions comprising the vaccines for treating and preventing tropical disease.

Provided herein are methods that include introducing into an inner ear of a mammal a therapeutically effective amount of an adeno-associated virus (AAV) vector that includes a nucleotide sequence encoding (a) a polypeptide including an antibody heavy chain variable domain operably linked to a signal peptide and a polypeptide including an antibody light chain variable domain operably linked to a signal peptide; (b) a polypeptide including an antigen-binding antibody fragment operably linked to a signal peptide; or (c) a soluble vascular endothelial growth factor receptor operably linked to a signal peptide.

Disclosed are compositions and formulations of non-porcine lipase and methods of treatment and manufacture thereof.

Nanoparticles, methods, and kits are provided for supplying nutrients and other therapeutic agents to transplanted cells. Nutrient deprivation is a significant factor which contributes to poor outcome of many cell transplants because cells receive insufficient nutrients until they are able to establish a functional microcirculation to support their metabolic and physiological needs after transplantation. Nanoparticles are provided for use in supplying nutrients and other therapeutic agents to transplanted cells to improve cell survival. Such nanoparticles can be used to supply nutrients and other factors to transplanted cells until the transplanted cells are able to develop a new microcirculation.

The present invention relates to a polymer composite for ultrasound-based cancer immunotherapy, which comprises an peroxalate derivatives, and a preparation method thereof. The polymer composite according to the present invention is a structure in which the peroxalate derivatives are encapsulated in an amphipathic polymer compound in which a biocompatible polymer and a sonosensitizer are combined. The peroxalate derivatives produce free electrons and carbon dioxide (CO.sub.2) by reaction with a high concentration of hydrogen peroxide (H.sub.2O.sub.2) in cancer tissue, the generated electrons raise the energy level of the sonosensitizer in the polymer composite to increase the amount of reactive oxygen species (ROS) production, thereby exhibiting an effect of increasing the death rate of cancer cells. In addition, by ultrasound treatment, immunogenic cell death (ICD) is induced due to the cavitation effect of the produced CO.sub.2, so molecules capable of activating immune cells in cancer cells are released without damage to induce an immune response to cancer. Therefore, the polymer composite according to the present invention is expected to be effectively used as an ultrasound-based cancer immunotherapeutic agent.

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

The present invention relates to a method for inducing an immune response manifested by type I interferon production in a synergistic manner comprising the sequential administration of danger signals within a certain timeframe and means for practicing the method. The present invention is particularly useful for immunomodulation, immunotherapy and vaccination.

Provided is a polymer comprising a hydrolysable polymer backbone, the polymer backbone comprising (i) monomer units with a side chain comprising a hydrophobic group; (ii) monomer units with a side chain comprising an oligoamine or polyamine; and (iii) monomer units with a side chain comprising a polyalkylene oxide, polyglycolic acid, polylactic acid, or combination thereof, as well as a composition comprising the polymer, and a method of delivering one or more biomolecules or synthetic variants thereof to a cell using the polymer and/or the composition.

The present invention relates to methods for producing particles of meloxicam using dry milling processes as well as compositions comprising meloxicam, medicaments produced using meloxicam in particulate form and/or compositions, and to methods of treatment of an animal, including man, using a therapeutically effective amount of meloxicam administered by way of said medicaments.
