Research is primarily oriented towards elucidation of the molecular and biological basis of inborn and acquired immunodeficiency disorders, to new theurapeutic strategies for such patients, to improving the success of allogeneic organ and bone marrow transplants as well as to giving the basis for future xenotransplantation. It is one of the most active research divisions of the Karolinska Institute and the most active at Huddinge University Hospital in terms of academic index ranking. The close collaboration between clinical specialists and basic scientists has been extremely fruitful and led to significant scientific contributions. Approximately 25-30 PhD graduate students are registered at the division, half of them with a medical background. A substantial portion of the graduate students are visitors from abroad.
Academic research is coordinated by several individual group leaders.
The clinical immunology laboratory gives complete immunological service to hospitals, primary health care centres and private practitioners. A diagnostic section for genetic diseases of the immune system is being established. The European registry for immunodeficiency patients is localized here, as well as the international registry for patients with Bruton's disease.
