Research in the Sautto lab is focused on the selection, cloning, characterization and engineering of monoclonal antibodies (mAbs), especially of human origin, and directed against infectious agents. In particular, the potential of these mAbs is investigated as possible drugs, able to directly neutralize infectious pathogens, or as indirect molecules to be exploited for the development of prophylactic approaches. Moreover, their possible engineering in order to improve (i.e. their binding or stability characteristics) or gain new functions (such as in the case of chimeric antigen receptors, CARs), represents a promising and alternative approach for difficult-to-eradicate infectious pathogens.
