In various aspects and embodiments the invention provides a method of treating multiple sclerosis in a subject in need thereof, the method comprising administering to the subject an effective amount of an oligodendrocyte-derived extracellular vesicle.

Provided herein is a method of preparation of a therapeutic formulation comprising extracellular vesicles packaged with fenretinide.

The present disclosure provides a composition comprising (a) exosome-like nanovesicles or exosomes and (b) a carrier, wherein the exosome-like nanovesicles or exosomes are extracted from Withania somnifera and methods of effecting a change in hair appearance, hair growth, hair pigmentation, hair follicle size or hair shaft size, comprising administering to the skin of a subject in need thereof an effective amount of such a composition.

Disclosed herein are compositions and methods related to megakaryocyte-derived extracellular vesicles derived from human pluripotent stem cells, where the megakaryocyte-derived extracellular vesicles may be utilized for drug delivery and treating various diseases.

Compositions comprising a cell-derived particle associated with Cannabidiol (CBD), and uses thereof in treating medical conditions that can benefit from Cannabidiol (CBD) are provided.

The present invention provides mesenchymal stem cells (MSCs) and extracellular vesicles comprising exogenous membrane embedded proteins. Pharmaceutical compositions comprising MSCs and extracellular vesicles are also provided. The present invention further provides a method of treating, preventing or ameliorating a viral infection, inflammation, and/or tissue fibrosis.

The present invention provides pharmaceutical compositions comprising membrane vesicles, including extracellular vesicles including those referred to as exosomes, loaded with an exogenous Phosphatase and tensin homolog (PTEN) inhibitor. Methods of treating neurological diseases, disorders or conditions using the extracellular vesicles are provided. Isolated extracellular vesicles loaded with an exogenous Phosphatase and tensin homolog (PTEN) inhibitor are provided as well.

A stem cell biomimetic microparticle and methods of manufacture are provided that comprise a core nanoparticle and an outer layer disposed on the core nanoparticle, the core nanoparticle comprising at least one stem cell-derived secreted factor or a population of stem-cell derived exosomes embedded in a biocompatible polymer core nanoparticle, and an outer layer obtained from a cell membrane. Also provided is a method of treating a pathological condition of a patient by delivering to the patient a composition comprising the stem cell biomimetic microparticle comprising at least one stem cell-derived secreted factor or population of stem cell-derived exosomes embedded in a biocompatible polymer core microparticle and an outer layer derived from red blood cell membranes or platelet membranes disposed on the biocompatible polymer core microparticle.

It discloses a dexamethasone-loaded macrophage-derived microvesicle as well as a preparation method and application thereof. The dexamethasone-loaded macrophage-derived microvesicle is formed by entrapping dexamethasone with a microvesicle derived from a murine macrophage cell line 264.7 cell. The dexamethasone-loaded macrophage-derived microvesicle of the present invention can be taken up by an injured cell more effectively, and fulfills the aim of ameliorating the kidney inflammation by inhibiting the activation of a proinflammatory signal pathway and infiltration of inflammatory cells. Meanwhile, the preparation method of the present invention is simple, convenient and efficient, and the prepared microvesicle is derived from the RAW 264.7 cells which are sufficient and widespread, and can be produced in large-scale.

A composition comprising sodium butyrate for the prevention and/or treatment of a viral infection caused by Rhinovirus. The composition may further comprise Vitamin D. The composition may be administered in the form of a tablet or capsule, in the form of an inhaler, or provided as a dietary supplement.
