Research description

My research is focused on understanding mechanisms and improving means for diagnosis of autoimmune disease.

Autoantibodies as markers of disease. We are using proteome arrays to characterize autoantibody responses and to identify biomarkers. We are also developing targeted antigen panels to support clinical diagnostics of autoimmune disorders. 

One of the autoantigens we have identified, transglutaminase 4, is a prostate-specific member of the transglutaminase protein family. Previous studies have identified other members of this protein family as autoantigens in distinct autoimmune disorders. Inspired by this, we now pursue remaining transglutaminases as candidate autoantigens.

Sex differences in immunity and disease. Women face a four-fold higher risk of developing an autoimmune disorder compared to men. As a means to understand the role of sex hormones, we follow men and women undergoing sex change with blood and fecal sampling before and at different time points during cross-sex hormone therapy. Multiple omics technologies are combined to achieve a broad view of how male and female hormones regulate the immune system.
