Lymphoproliferative disorders are heterogeneous in their pathogenesis, biological characteristics, clinical aspects, and response to treatment. Better insight in underlying molecular immunological mechanisms is crucial to completely understand this heterogeneity in order to design tailored treatment strategies for lymphoproliferative disorders. We are currently focusing on further unravelling the biological (signalling, genetics, epigenetics) and clinical heterogeneity of especially chronic lymphocytic leukemia (CLL) and large granular lymphocyte (LGL) leukemia. Additionally, as these leukemia types mostly arise in elderly individuals, studying the ageing of the normal immune system and the immune repertoire is key to understanding the pathogenesis of lymphoproliferative disorders.
