For the first time, the annual meeting of the T cell study group of the German Society of Immunology (DGfI) was held in Raitenhaslach, Bavaria, on the border of Germany and Austria. Organized by Dietmar Zehn (Freising) and Bertram Bengsch (Freiburg), over 80 participants enjoyed many talks and posters all about T cells. The Baumjohann Lab was very well represented with four (!) talks given by Luisa, Teresa, Maxi, and Elina about their PhD or MD projects.
