Research Focus

Dr. Tomer is a physician scientist, and his research program focuses on the immunogenetic, epigenetic and environmental mechanisms underlying thyroid autoimmunity and type 1 diabetes, and on targeting these mechanisms in order to develop novel therapies. His group has made several important discoveries, including: identifying new genes and mechanisms underlying the strong association between type 1 diabetes and autoimmune thyroiditis; demonstrating that CD40 and thyroglobulin are major susceptibility genes for thyroid autoimmunity; identifying a unique amino acid variant in the peptide binding pocket of HLA-DR that is key for the development of thyroid autoimmunity; dissecting the epigenetic mechanisms by which polymorphisms in the thyroglobulin and TSHR genes interact with environmental agents (e.g., viruses) to trigger thyroid autoimmunity; demonstrating that the hepatitis C virus can trigger autoimmune thyroiditis by directly infecting thyroid cells; and identifying a novel compound that can block antigen presentation in autoimmune thyroiditis.
