Abstract: 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.

Abstract: 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).

Abstract: A system and method for controlling a shared memory bus in a computer of a multi-processor system prevents collisions on the shared bus and ensures that the bus is full at system start-up. Steady state operations are maintained without the need for a queuing mechanism in the system's memory controller and in view of the memory modules of the shared memory having different read access times, with the system and method being implemented in a system that includes a central unit and multiple uni-directional buses that are disposed between a shared memory and a plurality of processors, with the central unit controlling access to, and use of, the shared buses of the system.
