T lymphocytes play crucial roles in cellular immunity against pathogens and tumors. On the other hand, deregulated T cell responses also contribute to inflammatory and autoimmune diseases. We are interested in the processes of generation, activation and regulation of T lymphocytes. Using state-of-the-art research tools and methods, we envisage the identification of molecules involved in those processes and their integration in cellular mechanisms, which may be translated into new treatments for cancer, and infectious or autoimmune diseases.
