Abstract: An extracellular vesicle loaded with a nucleic acid cargo and method for preparing the loaded vesicle is disclosed.

Abstract: A red blood cell extracellular vesicle (RBCEV) loaded with a nucleic acid cargo; method for preparing the loaded vesicle; and the therapeutic use of the vesicle thereof are disclosed. The nucleic acid cargoes may be DNA or RNA, single stranded or double stranded, as well as linear or circular.

Abstract: The application relates to extracellular vesicles derived from red blood cells and particularly, although not exclusively, extracellular vesicles derived from red blood cells containing a cargo. The cargo may comprise small molecules, proteins, nucleic acids or components of the CRISPR/Cas9 gene editing system. The extracellular vesicles derived from red blood cells may be used in the treatment of medical disorders such as a genetic disorder, inflammatory disease, cancer, autoimmune disorder, cardiovascular disease or a gastrointestinal disease. Also provided is a method for loading the cargo into the extracellular vesicles derived from red blood cells by electroporation.

Abstract: The invention relates to surface modified extracellular vesicles, wherein the extracellular vesicles comprise an exogenous polypeptide tag that is covalently linked to a membrane protein of the extracellular vesicles. In a particular embodiment, the tag is covalently linked to the membrane protein of microvesicles by sortase-mediated ligation. Methods of preparing said extracellular vesicles and methods of using said extracellular vesicles loaded with therapeutic molecules for treating a disease are also disclosed herein.

Abstract: An extracellular vesicle loaded with a nucleic acid cargo and method for preparing the loaded vesicle is disclosed.
