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.

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.

Provided herein are nanoparticles to encapsulate therapeutic agents and methods of use thereof for intracellular delivery and disease treatment. In particular, the present disclosure provides polymersomes for use in the delivery of therapeutic agents, e.g. stapled peptides, to diseased (e.g. cancer) cells.

The present invention provides hydrophilic bilirubin derivative particles containing a metal, a use thereof, and a preparation method therefor. The bilirubin derivative particles of the present invention form coordinate bonds with various metals, and thus can be used in MR diagnosis, CT diagnosis, photo-acoustic diagnosis, PET diagnosis, or optical diagnosis. The bilirubin derivative particles of the present invention can release an anticancer drug encapsulated therein to the outside by the combination with a platinum-based anticancer drug and the degradation by a stimulation of light/reactive oxygen species, and exhibit anti-inflammatory and anticancer activities, and thus the bilirubin derivative particles of the present invention have a concept of theranostics in which the bilirubin derivative particles can be for therapeutic uses as well as diagnostic uses.

The present invention utilizes carrier particles to present antigen peptides and proteins to the immune system in such a way as to induce 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 particles assemblies including a shell surrounding a core. The shell includes a particle-stabilizing random copolymer. The core includes a core random copolymer. The particle assemblies have a biomimetic design in which the polymeric components containing discrete chemical and biological functionalities are designed to spontaneously self-assemble into particles. Also provided herein are random copolymers having conjugated therapeutic agents that can be cleaved from the copolymers by an enzyme or water.

The application relates to liposomal nanovesicles comprising porphyrin-lipid conjugates within the liposomal lipid bilayer. Said porphyrin-lipid conjugate comprise porphyrins that are modified with a CH(R.sup.1)OR.sup.2 group and that chelate a metal ion. Such modifications of the porphyrin allow for ordered assembly in the lipid bilayer of the nanovesicles while resulting in a bathochromic shift in the wavelength of light absorbed by the porphyrin chromophore. These nanovesicles can be used for photothermal therapy, photodynamic therapy, photoacoustic imaging and fluorescence imaging. The application also teaches methods for preparing the porphyrin-lipid conjugates and the nanovesicles.

A telodendrimer-nanolipoprotein particle (t-NLP), comprising one or more membrane forming lipids, one or more telodendrimers, and a scaffold protein and a Chlamydia major outer membrane protein (MOMP) comprising a MOMP hydrophobic region, and related compositions methods and systems.

Nanolipoprotein particles having at least a scaffold protein component and a membrane lipid component and related compositions, methods and systems are described. The membrane lipid component includes at least one or more membrane forming lipids, one or more polymerized lipids and/or one or more polymerizable lipids.

Two disparate biological mechanisms which predispose to the dissemination and metastases of solid tumors is described. The treatment of metastatic lesions via topical and transdermal administration of therapeutic agents, such as Type 1 Cystatins, through intact skin, is directed to the inhibition of lysosomal cysteine cathepsin proteolytic enzymatic degradation of the extracellular matrix
