Abstract
Official abstract text for this publication.
Extracellular vesicles derived from native, photosynthetic, non-fermenting microalgae are provided. A method for isolating extracellular vesicles from native, photosynthetic, non-fermenting microalgae involving growth, centrifugation and ultracentrifugation steps is also provided. Use of the isolated extracellular vesicles as carriers for delivering diagnostic, therapeutic, nutraceutic and/or cosmetic agents is further provided.
First claim
Opening claim text (preview).
What is claimed is: 1 . An extracellular vesicle (EV) derived from a microalga, wherein the extracellular vesicle (EV) is a biogenic lipidic membranous nanovesicle having a particle size ranging from 50 to 300 nm, being a small extracellular vesicle (sEV) or from 300 nm to 2 μm, being a large extracellular vesicle (lEV) and comprises a lipidic bilayer membrane, and wherein the extracellular vesicle (EV) is derived from a native, photosynthetic, non-fermenting microalga and contains at least the extracellular vesicle protein marker Alix and one or more protein markers selected from the group consisting of enolase, actin and any combination thereof. 2 . The extracellular vesicle (EV) of claim 1 , wherein the microalga is selected from photosynthetic microalgal phyla Chlorophytes and Bacillariophytes. 3 . The extracellular vesicle (EV) of claim 1 , wherein the microalga is selected from the photosynthetic microalgal divisions Euglenophyta, Cryptophyta, Rhodophyta, Glaucophyta, Chromophyta and Chlorophyta. 4 . The extracellular vesicle (EV) of claim 1 , wherein said extracellular vesicle (EV) is used as a carrier for delivering a diagnostic, therapeutic, nutraceutic and/or cosmetic agent.
