The invention provides new compositions and methods for immunomodulation of individuals. Immunomodulation is accomplished by administration of immunomodulatory polynucleotide/microcarrier (IMP/MC) complexes. The IMP/MC complexes may be covalently or non-covalently bound, and feature a polynucleotide comprising at least one immunostimulatory sequence bound to a biodegradable microcarrier or nanocarrier.

Biodegradable immunomodulatory formulations and methods for use thereof

The invention provides methods of modulating an immune response to a second antigen which entail administration of a first antigen and an immunostimulatory polynucleotide. Modulation of the immune response is generally manifested as stimulation of a Th1 response.

Methods of modulating an immune response using immunostimulatory sequences and compositions for use therein

The invention provides methods of preventing and/or treating infection by a respiratory virus such as respiratory syncytial virus (RSV), particularly reducing infection and/or one or more symptoms of respiratory virus infection. A polynucleotide comprising an immunostimulatory sequence (an 'ISS') is administered to an individual which is at risk of being exposed to a respiratory virus, has been exposed to a respiratory virus or is infected with a respiratory virus. The ISS is administered without any antigens of the respiratory virus. Administration of the ISS results in reduced incidence and/or severity of one or more symptoms of respiratory virus infection.

Methods of preventing and treating respiratory viral infection using immunomodulatory polynucleotide sequences

Compositions are provided which include biodegradable microparticles with entrapped or adsorbed antigens, in combination with submicron oil-in-water emulsions. Also provided are methods of immunization which comprise administering to a vertebrate subject (a) a submicron oil-in-water emulsion, and (b) a therapeutically effective amount of a selected antigen entrapped in a microparticle.

Use of microparticles combined with submicron oil-in-water emulsions

The invention relates to new immunomodulatory compositions which comprise a cationic condensing agent, an immunomodulatory compound, and a stabilizing agent. The compositions of the invention typically form particles which have increased immunomodulatory activity as compared to immunomodulatory compounds not formulated in the compositions of the invention. Also provided are methods of making the compositions and methods for therapeutic use of the compositions.

Immunomodulatory compositions, methods of making, and methods of use thereof

Methods are provided for the treatment of hepatitis B virus (HBV) and hepatitis C virus (HCV) infections. A polynucleotide comprising an immunostimulatory sequence is administered to a individual who has been exposed to or infected by HBV and/or HCV. The polynucleotide is not administered with a HCV or HBV antigen. Administration of the polynucleotide results in amelioration of symptoms of HBV and/or HCV infection.

Methods of suppressing hepatitis virus infection using immunomodulatory polynucleotide sequences

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 form ration, 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.

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

The use of poly(lactide) or poly(lactide-co-glycolide) microparticles with adsorbed antigen is disclosed. The microparticles are useful for enhancing CTL responses to a selected antigen.

Use of microparticles with adsorbed antigen to stimulate immune responses

The invention provides new compositions and methods for immunomodulation of individuals. Immunomodulation is accomplished by administration of immunomodulatory polynucleotide/microcarrier (IMP/MC) complexes. The IMP/MC complexes may be covalently or non-covalently bound, and feature a polynucleotide comprising at least one immunostimulatory sequence bound to a biodegradable microcarrier or noncarrier.

The invention provides new methods of preventing and/or treating herpes virus infections, particularly reducing infection, one or more symptoms and recurrence of one or more symptoms of herpes simplex virus infection. A polynucleotide comprising an immunostimulatory sequence (an 'ISS') is administered to an individual which is at risk of being posed to alphaherpesvirinae, has been exposed to alphaherpesvirinae or is infected with alphaherpesvirinae. The ISS is administered without any alphaherpesvirinae antigens. Administration of the ISS results in reduced incidence, recurrence, and severity of one or more symptoms of alphaherpesvirinae infection.
