About the MBLL

The Molecular Biology of Leukaemia laboratory (MBLL) investigates the molecular and cellular mechanisms underlying leukaemia development using a range of biological models. Special interest is devoted to the research of mechanisms involved in molecular crosstalk with the micro-environment surrounding the cancer cells and the role of cell surface proteins (eg lymphotoxin and chemokine receptors) in leukaemogenesis. The MBLL group is actively investigating proteins and signalling pathways that are expressed and/or activated in leukaemia cells and leukaemia-associated stromal cells that contribute to leukaemogenesis. The long-term goal of the MBLL is to divulge how lymphocytes are malignantly transformed and pave the way for the development of new therapeutic approaches to treat lymphoma and leukaemia.
