HBZ and leukemia: Future studies will be focused on the analysis of HBZ interactome in Jurkat-HBZ cells, as well as in additional ATL cell lines more closely mimicking the leukemic process (47) and in fresh leukemic cells (14, 48) to further validate and possibly expand and compare proteomic data of HBZ interactors in other HTLV-1-derived ATL and in cells that are not derived from HTLV-1-induced leukaemia.
