FUNCTIONALIZATION OF T CELL DERIVED VESICLES AND USE THEREOFFOR THE PREPARATION OF IMMUNOGENIC PHARMACEUTICAL COMPOSITIONS

摘要

The present invention relates to compositions comprising vesicles released' from activated T lymphocytes, as well as to methods for their production and uses. Said vesicles contain a set of bioactive molecules which confer remarkable properties, such as antigen recognition, antigen presentation and other regulatory and effector functions. This invention also relates to methods for transferring or delivering antigenic molecules (e.g., peptides, peptide/MHC complexes, TCR or subunit thereof, etc.) to antigen presenting cells (APCs) using said vesicles, to induce specific immune responses, particularly specific CTL responses. The invention further relates to method s of delivering molecules selectively or specifically to target cells using sa id vesicles.
