  • Publication number: 20050042272
    Abstract: 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 methods of delivering molecules selectively or specifically to target cells using said vesicles.

  • Patent number: 6821778
    Abstract: This invention relates to methods of using human dendritic cells to present antigens for the induction of antigen-specific T cell-mediated immune responses. In particular, it relates to the isolation of dendritic cells from human blood, exposing the cells to antigens, co-culturing the antigen-pulsed dendritic cells with &ggr;&dgr;-T cell receptor-positive-T cells (&ggr;&dgr;-TCR+ T cells) obtained from unprimed or weakly primed individuals for the stimulation of antigen-specific T cell proliferative and cytotoxic activities. The dendritic cell antigen presentation system described herein has a wide range of applications, including but not limited to, activation and expansion of large numbers of antigen-specific major histocompatibility complex-unrestricted T cells for use in adoptive cellular immunotherapy against infectious diseases and cancer.
