Harald von Boehmer has studied the role of T lymphocytes in the immune system. In particular he has addressed the contribution of the T cell receptor

CD8
CD8 is a transmembrane glycoprotein that serves as a co-receptor for the T cell receptor . Like the TCR, CD8 binds to a major histocompatibility complex molecule, but is specific for the class I MHC protein. There are two isoforms of the protein, alpha and beta, each encoded by a different gene...

 helper cells , respectively. Further studies were concerned with the structure and function of the pre-T cell receptor and its role in controlling survival and differentiation of developing T cells that have succeeded in productive TCR beta rearrangement. Presently Harald von Boehmer studies the generation and function of regulatory T cells that have an essential role in preventing autoimmunity with the goal to exploit these cells in the prevention of and interference with unwanted immune reactions.
