Abstract: The present invention pertains to affinity chromatography isolation and purification of extracellular vesicles (EVs). The EVs of the present invention are engineered to enable highly specific binding to e.g. chromatography matrices, which is highly useful for affinity-based isolation and purification of EVs from complex biological fluids such as cell culture medium or biological fluids.

Abstract: The present invention pertains to engineered extracellular vesicles (EVs) for use in a variety of research, diagnostic, imaging and therapeutic applications. The EVs are engineered to enable incorporation and surface display of various proteins of interest, which may be exogenous and/or endogenous in nature. The coating of EVs is achieved through inventive protein engineering of EV polypeptides, and the present invention thus relates to methods for coating of EVs, EVs per se, as well kits, detection methods, diagnostic applications, imaging and delivery methods based on said engineered EVs.

Abstract: The present invention pertains to inter alia methods for purifying extracellular vesicles including exposing a sample comprising at least one extracellular vesicle to ultrafiltration; and exposing the sample following the ultrafiltration in step (i) to size exclusion liquid chromatography.

Abstract: The present invention pertains to an inventive release mechanism for extracellular vesicle (EV)-mediated intracellular and intramembrane delivery of therapeutic polypeptides. More specifically, the invention relates to EVs comprising polypeptide constructs which comprise a therapeutic polypeptide releasably attached to an exosomal polypeptide. Furthermore, the present invention pertains to manufacturing methods, pharmaceutical compositions, medical uses and applications, and various other embodiments related to the inventive EVs.

Abstract: The present invention relates to methods for loading extracellular vesicles (EVs) with a pharmacological agent. The invention discloses the use of cell-penetrating peptides as carriers into EVs, using either a non-covalent or covalent loading approach. Furthermore, the present invention pertains to medical uses and compositions comprising such pharmacological agent-loaded EVs.

Abstract: The present invention pertains to inter alia therapeutic delivery vesicles, for instance exosomes or microvesicles, comprising polypeptide constructs, methods for producing said therapeutic delivery vesicles, pharmaceutical compositions and medical uses thereof. The therapeutic polypeptide constructs comprised in the extracellular delivery vesicles enable sequestering target molecules of interest, to treat e.g. neuro-inflammatory diseases and cancer.

Abstract: The present invention pertains to extracellular vesicle (EV) therapeutics, wherein the EVs are coated with proteins containing Fc domains (such as antibodies) for i.a. targeting and therapeutic applications. The coating of EVs is achieved through inventive protein engineering of EV polypeptides. The present invention thus relates to methods for coating of EVs, EVs per se, as well as pharmaceutical compositions and medical applications of such EVs coated with Fc containing proteins.
