Areas of Interest

In one research area, my laboratory is developing methods to study the structure and folding of DNA and RNA molecules. A key aspect of this work involves the use of chemically-modified nucleotides as probes of structure, function, and folding. For example, we have engineered disulfide cross-links into medium-sized RNAs to probe folding pathways, much in the way disulfide bonds have been used to explore aspects of protein folding. These cross-links have allowed the first structural assessment of an RNA folding transition state which is important for developing mechanistic model of folding.
A second research area is aimed at defining the binding properties of anti-DNA autoantibodies. Anti-DNA autoantibodies are a hallmark of the autoimmune disorder systemic lupus erythematosus. In a process involving antigen recognition, these antibodies mediate the kidney inflammation that results in much of the morbidity and mortality associated with lupus. However, the specific DNA antigens recognized by anti-DNA and the way in which anti-DNA interact with these molecules remains poorly understood. Using in vitro selection experiments we have identified high affinity consensus sequences for several monoclonal anti-DNA autoantibodies and we are now correlating their binding properties and pathogenicity. Not only do these experiments provide knowledge about the pathology of lupus, but they also provide fundamental insight about protein-DNA interactions in general.

The third avenue of research in my laboratory is aimed at developing small molecule agents to treat lupus and other autoimmune disorders. At present, broad-acting immunosuppressive agents are typically employed as therapeutics for lupus and related disorders. However, these drugs produce serious side effects that limit treatment. We have identified a class of pro-apoptotic benzodiazepines that in several animal models, effectively treats autoimmune disease by selectively killing disease-determining lymphocytes. Unlike current therapies, our compounds are not adversely immunosuppressive. Current efforts on this project focus on delineating the signaling pathways that mediate the benzodiazepine-induced death of lymphocytes and how this process leads to disease improvement.
