  • Publication number: 20120107317
    Abstract: The subject invention provides novel uses of cytoplasmic c-Myc for modulation of innate immune responses. The invention is based, at least in part, on the surprising discovery that cytoplasmic c-Myc, instead of nuclear c-Myc, modulates pro-inflammatory immune responses via its role as a positive feedback regulator. Specifically, the subject invention provides methods for treatment or amelioration of inflammatory diseases and/or immune disorders via inhibition c-Myc expression or its activity. Also provided are methods for the development of therapeutic agents for treating infection, inflammation, immune diseases and autoimmune diseases.
