IMMUNOLOGY, NANOBIOLOGY, AND THERAPUETIC INTERVENTIONS FOR HUMAN DISEASE
The overall focus of our laboratory investigates how the immune system is involved in the pathogenesis of human diseases, including asthma, autoimmunity and cancer, and novel ways to treat disease including nanotechnology based approaches.
Asthma and beta-adrenergic agonists: A long standing interest of our laboratory has been to determine the underlying basis for the negative side effects of a commonly used class of asthma medications. Although beta-adrenergic agonists are effective in relieving the symptoms of asthma, serious concerns regarding their safety have persisted for more than 20 years. Recently, the FDA halted a large-scale study designed to examine the safety of these medications due to serious and life-threatening exacerbations and placed a black box warning on these drugs. In an effort to understand the molecular basis for adverse side effects, we have determined that an important regulatory protein (CD40L) expressed on T cells of the immune system is abnormally regulated by these drugs. Beta-agonists, by increasing cAMP levels in the cell, can elevate the expression of CD40L protein on T cells from asthmatics. This response is predicted to promote the underlying inflammatory responses contributing to disease. Conversely, beta-agonists decrease the expression of CD40L in healthy subjects. The goal of our research is to determine the molecular and cellular mechanisms leading to dysregulated CD40L protein expression in asthma. These finding should further our understanding of disease mechanisms, therapeutic intervention, and potentially lead to the identification of at-risk populations for adverse drug response.
Nanotechnology and biomedical applications: An active area of research in our lab is investigating the potential applications of metal oxidenanomaterials on the immune response and treatment of human diseases including cancer and autoimmunity. Nanoparticles with sizes in the 1 – 100 nm range,comparable to the sizes of naturally occurring biological molecules, are very attractive materials for manipulating biological structures and systems. When reduced to the nanoscale, many benign materials develop toxicity or other novel attributes, presumably due to the increased reactivity of the material surface. We have determined that different nanoparticle systems induce toxicity in a cell-specific and microenvironment-dependent manner. By controlling nanoparticle selectivity to specific cell types by design, we are currently exploring novel biomedical applications including cancer therapy and drug delivery.
Novel drug candidates and inflammatory disease: We are investigating the potential utility of novel anthracycline drug analogs for the treatment of autoimmune diseases. The compound, DIDOX, belongs to a family of drugs called anthracyclines that are commonly prescribed for the treatment of cancer. Although anthracyclines have potent anti-proliferative effects that make them effective chemotherapeutic agents, a serious side effect of cardiotoxicity can develop 10-20 years later. A new drug analog, DIDOX, has been structurally modified to eliminate the molecular components associated with cardiotoxicity which opens the possibility of using this drug for the treatment of non-life threatening diseases such as psoriasis. We have determined that DIDOX effectively inhibits in vitro T cell responses as well as inflammatory responses in vivo. Future goals will be to evaluate the efficacy of this compound in animal models of psoriasis and other inflammatory diseases and to delineate the molecular mechanisms of immunosuppressive action.
