An immunostimulatory lipoplex is provided. The immunostimulatory lipoplex includes a liposome and at least one immunostimulatory nucleic acid drug, and the immunostimulatory nucleic acid drug is complexed with the liposome The liposome includes 40 to 85 mol % of cationic lipid, 10 to 50 mol % of cholesterol, and 0.001 to 20 mol % of modified polyethylene glycol lipid. A pharmaceutical composition including the immunostimulatory lipoplex is also provided

A hydrogel for in-vivo release of medication includes at least one medication, where the hydrogel includes (i) a protein-based biopolymer functionalized with a functionalisation agent that is able to form guest-host interactions with oxidized β-cyclodextrin, preferably a primary aminoalkylphenol, more preferably gelatin functionalized with tyramine (GTA) and (ii) oxidized β-cyclodextrin (oβ-CD), where the hydrogel is cross-linked via exposure to visible light in presence of a biocompatible photoinitiator, resulting in a degree of swelling in the range of 2-20 calculated as (swollen weight−dry weight)/dry weight. It further relates to a method for its preparation, as well as to a medication for treatment of musculoskeletal disorders, preferably for treatment of infection, inflammation, malignant processes, growth disorders, degenerative disorders or treatment of pain arising from (surgical treatment of) these disorders.

In one aspect, the disclosure provides mesoporous silica nanoparticles (MSNPs), monodisperse populations of MSNPs and related protocells which exhibit cell binding specificity. For example, MSNPs and protocells of the disclosure may be used to target specific delivery of therapeutic agents to CD19 or EGFR expressing cancer cells, or target specific delivery of therapeutic agents to other cell types. Related protocells, pharmaceutical compositions and therapeutic and diagnostic methods are also provided.

Methods for sensitizing tumors and/or cancers in subjects to therapeutic agents are provided. In some embodiments, the methods include administering to the subject one or more compositions that include an effective amount of an inhibitor of TRIM37 activity. Also provided are methods for sensitizing tumors and/or cancers in subjects to therapeutic agents by administering to the subjects one or more compositions that include an effective amount of an inhibitor of TRIM37 activity and purified and isolated antibodies and fragments thereof that have at least one paratope and further have a linker sequence through which the antibody can be conjugated to a carrier in which the linker sequence includes the amino acid sequence ((X).sub.3Cys(X).sub.3, wherein each X is independently any amino acid.

Provided herein are nanocarriers for delivery of immunosuppressive agents. In some embodiments, provided herein are nanocarriers comprising a core comprising a poly(ethylene glycol)-block-poly(propylene sulfide) copolymer and least one therapeutic agent. In some embodiments, the nanocarriers may further comprise a targeting ligand displayed on a surface of the nanocarrier. The at least one therapeutic agent may be an anti-inflammatory agent. The disclosed nanocarriers may be incorporated into pharmaceutical compositions for use in methods of treating an inflammatory condition or preventing transplantation rejection in a subject.

The present invention utilizes carrier particles to present antigen peptides and proteins to the immune system in such a way as to include antigen specific tolerance. The carrier particle is designed in order to trigger an immune tolerance effect. The invention is useful for treatment of immune related disorders such as autoimmune disease, transplant rejection and allergic reactions.

Provided herein are improved delivery systems for oligonucleotides, said delivery system comprising a liposome that comprises neutral phospholipids and a P-ethoxy oligonucleotide, which targets a STAT3-encoding polynucleotide. Methods of treating patients with said delivery systems are also provided.

The present invention relates generally to vesicles such as liposomes, colloidosomes, and polymersomes, as well as techniques for making and using such vesicles. In some cases, the vesicles may be at least partially biocompatible and/or biodegradable. The vesicles may be formed, according to one aspect, by forming a multiple emulsion comprising a first droplet surrounded by a second droplet, which in turn is surrounded by a third fluid, where the second droplet comprises lipids and/or polymers, and removing fluid from the second droplet, e.g., through evaporation or diffusion, until a vesicle is formed. In certain aspects, the size of the vesicle may be controlled, e.g., through osmolarity, and in certain embodiments, the vesicle may be ruptured through a change in osmolarity. In some cases, the vesicle may contain other species, such as fluorescent molecules, microparticles, pharmaceutical agents, etc., which may be released upon rupture. Yet other aspects of the invention are generally directed to methods of making such vesicles, kits involving such vesicles, or the like.

Disclosed is an optimal peptide-liposome complex capable of multivalent crosslinking with PD-L1 on the cell surface to induce degradation of PD-L1. The peptide-liposome complex effectively blocks PD-L1, an immune checkpoint on the surface of cancer cells, and prevents the recycling of PD-L1 by intracellular metabolism to induce complete degradation of PD-L1 in cancer cells, achieving an increased therapeutic effect on cancer.

A composition comprising at least one nanobomb comprising at least one first particle and at least one second particle in close proximity to the first particle. The at least one first particle is able to absorb electromagnetic radiation so as to generate a vapor bubble. The generation of the vapor bubble causes the at least one second particle to be propelled over a distance D. The composition is suitable to alter a biological barrier, in particular, for deforming, permeabilizing or perforating a biological barrier. A method to alter biological barriers is also disclosed.
