Research Interests:

Dr. Rappa's work at USA is mainly in the area of preclinical cancer pharmacology, using a gene therapy approach. After the development and study of MRP1 knockout models, the main research focus is now on the design of drug resistance-expressing retroviral vectors to protect the bone marrow of cancer patients from collateral toxicity of chemotherapy. To this aim, in vitro and in vivo models based on bone marrow stem/progenitor cells, are being developed, and new anticancer drug strategies tested.
