Abstract: Methods of use of Chaperonin 10 (Cpn10) are provided for regulating Toll-like receptor signaling and/or Toll-like receptor inducible immunomodulator secretion. Cpn10 negatively regulates Toll-like receptor agonist-induced pro-inflammatory cytokine and chemokine secretion, examples being IL-6 and RANTES, respectively. Cpn10 positively regulates Toll-like receptor agonist-induced anti-inflammatory cytokine and chemokine secretion, an example being IL-10. These immunoregulatory activities of Cpn10 may be useful in the treatment of diseases, disorders and conditions resulting from excessive pro-inflammatory cytokine and chemokine secretion. This invention also relates to producing, designing and/or screening Cpn10 agonists and antagonists according to their ability to regulate Toll-like receptor signaling and/or Toll-like receptor inducible immunomodulator secretion.

Abstract: The present invention relates to a recombinant polyepitope cytotoxic T lymphocyte vaccine. The vaccine comprises at least one recombinant protein including a plurality of cytotoxic T lymphocyte epitopes from one or more pathogens, wherein the at least one recombinant protein is substantially free of sequences naturally found to flank the cytotoxic T lymphocyte epitopes. In addition the present invention also provides a polynucleotide including at least one sequence encoding a plurality of cytotoxic T lymphocyte epitopes from one or more pathogens.

Abstract: A flaviviral expression vector, construct and system are provided that each comprise a flaviviral replicon that faciliates intracellular self-replication leading to high-level expression of RNA and protein(s) encoded by a heterologous nucleic acid. The flaviviral expression vector, construct and system preferably use a Kunjin virus replicon and are of particular use as a vaccine delivery system that facilitates expression of immunogenic proteins and peptides that induce protective T cell immunity to viral infections and cancer. Vaccines may be administered in the form of DNA, RNA or virus like particles.

Abstract: The present invention relates generally to chemical agents useful in the treatment and prophylaxis of inflammatory conditions or in the amelioration of symptoms resulting from or facilitated by an inflammatory condition in a mammalian animal including human and primate, non-mammalian animal and avian species. More particularly, the present invention provides a chemical agent of the macrocyclic diterpene family obtaining from a member of the Euphorbiaceae family of plants or botanical or horticultural relatives thereof or derivatives or chemical analogues or chemically synthetic forms of the agents for use in the treatment or prophylaxis of an inflammatory condition or in the amelioration of symptoms resulting from or facilitated by an inflammatory condition in a mammal, animal or avian species.

Abstract: H-2 class I negative, HLA-A2.1 transgeniic HHD mice were used for a comparative evaluation of the immunogenicity of HLA-A2.1 restricted human tumor-associated CTL epitopes. A hierarchy was established among these epitopic peptides injected into mice in IFA which correlates globally with their capacity to bind and stabilize HLA-A2.1 molecules. Co-injection of a helper peptide enhanced most CTL responses. In contrast, classical HLA class I transgenic mice which still express their own class I molecules did not, in most cases, develop H.A.-A2.1-restricted CTL responses under the same experimental conditions. Different monoepitopic immunization strategies of acceptable clinical usage were compared in HHD mice. Recombinant Ty-virus-like particles, or DNA encoding epitopes fused to the hepatitis B virus middle envelope protein gave the best results. Using this latter approach and a melanoma-based polyepitope construct, CTL responses against five distinct epitopes could be elicited simultaneously in a single animal.

Abstract: The present invention relates generally to chemical agents useful in the treatment and prophylaxis of protein kinase C (PKC) related conditions in mammals, including humans and primates, non-mammalian animals and avian species. More particularly, the present invention provides a chemical agent of the macrocyclic diterpene family obtainable from a member of the Euphorbiaceae family of plants or botanical or horticultural relatives thereof or derivatives or chermical analogues or chemically synthetic forms of the agents for use in the treatment or prophylaxis of PKC-related conditions in mammalian, animal and avian subjects. The subject chemical agents are also useful for modulating expression of genetic sequences including promotion and other regulatory sequences.

Abstract: The present invention relates generally to chemical agents useful in the treatment and prophylaxis of infection by pathogenic or potentially pathogenic entities, or entities capable of opportunistic infection in mammals, including humans and primates, non-mammalian animals and avian species. More particularly, the present invention provides a chemical agent of the macrocyclic diterpene family obtainable from a member of the Euphorbiaceae family of plants or botanical or horticultural relatives thereof or derivatives or chemical analogues or chemically synthetic forms of the agents for use in the treatment or prophylaxis of infection by pathogenic entities in mammalian, animal and avian subjects.
