I graduated in Medicine at the University of Torino, Italy, after spending some time as a visiting research student at Mount Sinai Medical School (New York) and Harvard Medical School (Boston). I then joined the lab of Prof Antonio Lanzavecchia at the Basel Institute for Immunology in 1996, to work on human Dendritic Cells, within the EUNIDI network (European Union Network for Investigation of Dendritic Cell Immunotherapy). I moved to Oxford at the end of 1999 and joined the group of Prof Vincenzo Cerundolo in the MRC Human Immunology Unit.
My main research interest is understanding how Dendritic Cells, the 'specialized' antigen presenting cells of the immune system, orchestrate immune responses and efficiently prime antigen specific T cells. Specifically, I am interested in understanding how a subset of immune cells known as innate-like T cells, or unconventional T cells, modulate Dendritic Cell activation. The two main subsets of innate like T cells I have been studying are CD1d-restricted iNKT cells and MR1-restricted MAIT cells, which recognize non-peptidic antigens.
To understand the molecular mechanisms of iNKT cell and MAIT cell activation and their cross-talk with Dendritic Cells, I use a range of cellular and molecular techniques, and I am particularly intererested in developing multiparameter flow cytometry, using our recently acquired BD X50 Symphony instrument. In addition to understanding the fundamental biology of innate like T cells, I am investigating their role in a disease context, such as cancer. Because of their abundance in humans and their key location at mucosal sites, I am studying the function of innate-like T cells in modulating the balance between graft versus host disease (GvHD) and graft versus leukemia (GVL) in patients who undergo bone marrow transplantation for hematological malignancies.
