    Research Interests

    We study T cells. T cells are amongst the cells which recognize that an infection is occurring in the body. They accomplish this in an unexpected way, by reacting with fragments of the infection bound to special proteins of the body, the MHC proteins. We are trying to find out how T cells learn to react in this way. We are also interested in the ways in which T cells are prevented from attacking MHC proteins bound to fragments of their own host. In most people such attack is efficiently avoided. However, in some individuals T cells do react in this way, and this event causes autoimmune diseases such as rheumatoid arthritis and juvenile diabetes. On the other side of the coin, the vaccines work by stimulating the ability of T cells to attack invaders. We study how vaccines accomplish this, with the hope that this understanding will help us design better vaccines.
