Immunomodulatory proteins- or targeting proteins-expressing nanovesicles, methods of preparing the nanovesicle and use thereof

The present invention relates to nanovesicles which express immunomodulatory proteins or targeting proteins, methods for preparing the same and uses thereof. More specifically, the present invention provides plasma membrane bleb-based nanovesicles which are prepared more homogeneously than existing plasma membrane bleb-based nanovesicles, by using cell lines expressing various immunomodulatory proteins or targeting proteins in the plasma membrane as materials, methods for preparing the nanovesicles, pharmaceutical compositions including the nanovesicles, methods for inducing immunity using the nanovesicles and methods for signal transduction or targeting using the nanovesicles.
