Overview

The pathophysiology of primary immunodeficiencies (PID), which encompass a broad range of different diseases with susceptibility to infection and/or a deregulated inflammatory response, is poorly understood. Available treatments are often not specific for a distinct target and might be associated with side effects. To elucidate pathophysiology of different PIDs, stool, urine, blood, tissue biopsies and/or bone marrow will be collected and analysed for anti-microbial activity and inflammatory response. In a second step, targeted treatment for different PIDs might be developed preclinically and ex vivo according to underlying pathophysiology.
