摘要： Nanoparticle-based vaccines, compositions, kits and methods are used for the effective delivery of one or more antigens in vivo for vaccination and antibody (e.g., monoclonal antibody) production, and for the effective delivery of peptides, proteins, siRNA, RNA or DNA to PAPCs or MHC class II positive cells (e.g. tumor cells). Antigens may be, for example, DNA that results in expression of the gene of interest and induction of a robust and specific immune response to the expressed protein in a subject (e.g., mammal). Antigens may also be immunogenic peptides or polypeptides that are processed and presented. In one embodiment, a nanoparticle-based method to deliver antigens in vivo as described herein includes injection of a vaccine composed of a DNA encoding at least one antigen, or at least one antigenic peptide or polypeptide conjugated to a charged dendrimer (e.g., PADRE-derivatized dendrimer) that is also conjugated to a T helper epitope (e.g., PADRE). Negatively-charged plasmids bind naturally to a positively-charged PADRE-dendrimer, while peptide or polypeptide antigens can be chemically linked to the PADRE-dendrimer if they are not negatively-charged. Alternatively, negatively-charged dendrimers may be used. The compositions, kits, vaccines and methods described herein have both prophylactic and treatment applications, i.e., can be used as a prophylactic to prevent onset of a disease or condition in a subject, as well as to treat a subject having a disease or condition. A vaccine as described herein can be used to mount an immune response against any infectious pathogen or cancer.

摘要： Nanoparticle-based compositions, assays, kits, methods and platforms for delivering an antigen (peptides, proteins) or a nucleic acid encoding an antigen to professional APCs (PAPCs) result in the generation of autologous APCs that present a natural peptide repertoire of the antigen for use in assessing the efficacy of a vaccine (e.g., a cytotoxic T lymphocyte (CTL) response to a particular antigen) or other therapy or intervention (cell-based therapy, adjuvant therapy, etc.). The compositions, kits, assays and methods also can be used for delivering a drug or biologic or portion thereof to APCs for assessing the immunogenicity of drugs and biologics. The composition, kits, assays and methods involve the combined use of MHC targeting, universal DR binding peptides (e.g., PADRE, HA) with charged (e.g., positively-charged) highly branched polymeric dendrimers (e.g., PAMAM and other dendrimers) as vehicles for the targeted delivery of nucleic acids, peptides, biologics, drugs, or polypeptides to APCs, giving rise to a new nanoparticle-based method for assessing the immune response (CTL response) to a vaccination or other therapy or intervention, or for assessing the immunogenicity of a biologic or drug. Targeted delivery of nucleic acids, peptides, biologics, drugs, or polypeptides to APCs for effective expression and processing generates more physiologically relevant target antigens for evaluation of cell-mediated immune responses to vaccination, for example, and provides a low-cost approach for rapid generation of reagents and development of assay systems for more accurate profiling of immunological responses to infection, immunization, and other therapies or interventions. Immunoevaluation kits using targeted nanoparticle-based antigen delivery are described herein.
