Acute myeloid leukemia is a very heterogeneous disease, the usual treatment is very aggressive and with severe side effects. In the investigation of a new, more effective drug, researchers led by the Oncogenesis and Antitumoral Research Group of the Sant Pau Hospital Research Institute – IIB Sant Pau (Ramon Mangues, Isolda Casanova and Víctor Pallarès) attached to the CIBER-BBN, have demonstrated the efficacy of the self-created nanoparticle that blocks the spread of leukemia cells in animal models of acute myeloid leukemia and directly attacks tumor cells without damaging healthy ones, minimizing adverse effects.
