The Research


Our group focuses on the design and development of technology platforms as nanomedicine strategies in specific clinically relevant situations such as in cancer, genetic diseases and immunomodulation, through the characterization of intracellular trafficking and signaling pathways to efficiently overcome specific cellular barriers. The modulation of intracellular trafficking through the use of colloidal systems purposely engineered at the nano-scale addresses the need to clarify the mechanisms of drug transport to specific intracellular targets at the endocytic or cytosolic level, including new strategies for antigen presentation by dendritic cells and macrophages. New intracellular targets are also being aimed to maximize the potential use of new innovative technologies arising from better characterization of intracellular molecular biophysics.
