93272 - Advanced Immunology

Learning outcomes

At the end of the classes, the student will know about the cellular and molecular mechanisms that regulate the functioning of the immune system, as well as the present-day, state-of-the-art possibilities to deploy immune activities for therapeutic purposes. In particular, the student will know about: i) the genetic strategies that allow the diversification of the immune responses to antigens; ii) the generation and use of monoclonal antibodies; iii) immunosuppression strategies; iv) generation of chimeric antigen receptors.

Teaching methods

Frontal lessons with ppt slides unless otherwise stated by current provisions.

Assessment methods

Oral examination in presence. Online exams with Microsoft Teams platform in oral form are allowed only upon official clearance by the Study Course Secretary. In this case, students must register as usual in Almaesami, and they will receive an e-mail with the link and timetable of the exam session.

Teaching tools
