The research activity of the Microbiology and Virology Research Unit mainly focuses on the study of human adaptive immunity to clinically relevant human viral and bacterial pathogens. The fields of study of the unit spans from viruses responsible for persistent infections such as HCV or HIV to the study of human humoral immunity elicited against bacterial pathogens. The dissection of the B-cell response is mainly performed by using Phage Display techniques allowing the identification of human antibodies elicited against protective epitopes on the microorganism of interest. The availability of such antibodies can shed light on the complex interplay between human pathogens and human immune system. Moreover, the identification of antibodies exerting anti-microbial activity can also trigger the development of both novel immunotherapeutic tools and mimotopes possibly able to elicit protection in vivo.
