  • Publication number: 20170159057
    Abstract: The present invention relates to expression of ROR?t in cells and tissues and the effect of expression of this gene on proliferation of specific immune cells and in promotion of immune cell aggregates and in induction of IL17 producing cells. Furthermore, the invention relates to methods and agents that may decrease function of the gene product (the protein) or expression of this gene in individuals experiencing an inflammatory condition, an autoimmune disease or a food allergy, or any other condition whereby it is desirable to inhibit an immune response. In addition, methods and agents useful for enhancing the function of ROR?t with agonists or expression of this gene are also considered for use whereby it is desirable to increase immunity to a pathogen or tumor cell, for example, for use in conjunction with a vaccine. Screening methods for identifying novel modulators (antagonists and agonists) of ROR?t are also disclosed.

  • Patent number: 9358281
    Abstract: The present invention relates to enhancing, modulating or stimulating the innate immune response to HIV-1 and other viral pathogens and to the modulation and application of immune modulators and peptides for HIV-1 or other pathogen vaccines. The invention provides methods and means to activate an innate response to HIV-1 utilizing or via the HIV capsid protein or peptide, including modulating the binding of cyclophilin A to HIV capsid protein and modulating the ability of HIV to activate the major innate transcription factor IRF3 and interferon. Methods and assays are provided for screening for compounds, agents, or peptides capable of enhancing or activating innate immune response, particularly to HIV-1.

  • Publication number: 20150224152
    Abstract: The present invention relates to methods for treating or reducing the risk of or preventing diseases caused by or associated with pathogenic bacteria. More particularly, the present invention relates to methods for treating or reducing the risk of or preventing diseases caused by or associated with pathogenic bacteria of the gastrointestinal (GI) tract. The present invention further relates to methods for promoting pathways induced by commensal bacteria of the GI tract that lead to Th17 differentiation, which in turn leads to localized and systemic accumulation of Th17 cells. Compositions and medicaments are also described herein that are used alleviate and/or prevent symptoms associated with diseases caused by or associated with pathogenic bacteria. Accordingly, the compositions, medicaments and methods described herein may be used to address the needs of patients or subjects that would benefit from increased Th17 cell differentiation.
