Immunostimulatory Combinations for Vaccine Adjuvants

This invention discloses immunostimulatory combinations of Tumor Necrosis Factor Receptor Superfamily (TN-FRSF) agonists, Toll-Like Receptor (TLR) agonists, “domain present in NAIP, CIITA, HET-E, TP-I (NACHT)-Leucine Rich Repeat (LRR)” or “NLR” agonists, RIG-I-Like Helicase or “RLH” agonists, purinergic receptor agonists and cytokine / chemokine receptor agonists, together with delivery methods. The combinations, when used alone at the site of pathology, provide immunostimulation that induces host humoral and cellular immunologic responses to eliminate pathogens or neoplasms. Alternatively, when the combinations are used with a defined antigens, these combinations can induce focused humoral and cellular immunologic responses useful as prophylactic and / or ameliorative therapeutic modalities for infections and the treatment of neoplastic disorders.

Immunomodulatory compositions containing an immunostimulatory sequence linked to antigen and methods of use thereof

The invention provides classes of immunomodulatory compositions which comprise an average of one or more immunostimulatory sequence (ISS) containing polynucleotide conjugated, or attached, to antigen. The extent of conjugation affects immunomodulatory properties, such as extent of antigen-specific antibody formation, including Th1-associated antibody formation, and thus these various conjugate classes are useful for modulating the type and extent of immune response. The invention also includes methods of modulating an immune response using these compositions.

This invention provides methods to prepare and use immunostimulatory cells for enhancing an immune response. The invention provides a method for preparing mature dendritic cells (DCs), comprising the sequential steps of: (a) signaling isolated immature dendritic cells (iDCs) with a first signal comprising an interferon gamma receptor (IFN-γR) agonist and / or a tumor necrosis factor alpha receptor (TNF-αR) agonist to produce signaled dendritic cells; and (b) signaling said signaled dendritic cells with a second transient signal comprising an effective amount of a CD40 agonist to produce CCR7+ mature dendritic cells. Also provided by this invention are enriched populations of dendritic cells prepared by the methods of the invention. Such dendritic cells have enhanced immunostimulatory properties and increased IL-12 secretion and / or decreased IL-10 secretion.
