Provided are microvesicles isolated from milk, compositions thereof and uses for the preparation of milk formulas. Further provided are microvesicles, including exosomes and/or fat globules which encapsulate various miRNA molecules and uses thereof, as exemplified by supplementing milk formulas.

The present invention provides exosomes as drug delivery vehicles, compositions comprising a therapeutic agent encapsulated within such exosomes, methods of producing such exosomes and compositions thereof, as well as methods of delivering such exosomes and compositions to a specific patient tissue or organ. The present invention also provides methods of treating a disease, disorder, or condition such as cancer, an inflammatory disease, an infectious disease, an allergic disease, or an autoimmune disease, comprising administering to a patient in need thereof a provided therapeutic-loaded exosome or a pharmaceutical composition thereof.

A composition is provided that comprises a therapeutic agent encapsulated by a milk-derived microvesicle. The compositions can include therapeutic agents such as phytochemical agents or chemotherapeutic agents, while the milk-derived microvesicle can be derived from raw milk or colostrum. Further provided are methods for isolating a microvesicle that includes the steps of obtaining an amount of milk, and subjecting the milk to a series of sequential centrifugations configured to yield greater than about 300 mg of microvesicle protein per 100 ml of milk. Methods of modifying an immune response and treating a cancer in which a milk-derived microvesicle composition is administered are also provided.

The present disclosure relates to the field of pharmaceutical preparations, and in particular to use of a milk exosome in the manufacture of a drug carrier. The present disclosure uses milk exosomes as a drug carrier. The exosomes are derived from milk with safety and reliability, and has the functional properties of milk exosomes. Using the exosomes as a drug carrier can achieve oral administration of protein drugs. Using the milk exosomes to load liraglutide can achieve oral administration of liraglutide and treat type 2 diabetes.

The present invention relates to the field of biotechnology, and particularly to milk derived extracellular vesicles, and provides a process for isolating such extracellular vesicles from milk and milk related fluids. The present invention is also related to compositions containing said extracellular vesicles derived from milk, particularly suitable for use in pharmaceutical, veterinary, cosmetic and/or nutraceutical applications.
