Department of Microbiology and Immunology
The department focuses on the study, prevention and treatment of important diseases caused by viruses, bacteria, fungi and parasites, the study of the complex host-microbiome interaction, and the study of the host immune system in infections, cancer, kidney diseases, autoimmunity, allergy and organ transplantation.
About the Department
The Department of Microbiology and Immunology consists of 15 laboratories and includes the Rega Institute. The Rega Institute has a long-standing expertise in technologies for microbiological, biochemical, immunological, and cell biological in silico, in vitro, and in vivo research with the use of animal models and clinical specimens. The central themes of microbiology (infections) and immunity (defence against infections) are intrinsically interlinked, providing opportunities for complementary research activities, and creating possibilities for applications in diagnostics and therapy of emerging and therapy-resistant infections, tumours, and autoimmune diseases.
As a department, we are committed to cutting-edge fundamental and clinical research, with as final aims the development of innovative diagnostics and therapeutic services that will benefit patients everywhere. We aspire to uphold the highest student-oriented standards of learning, education, and mentoring. The Department of Microbiology and Immunology wants to create an academic environment for its faculty, research staff and students that is collegial, productive, challenging, flexible, collaborative, motivating and supportive of career development.

We are interested in the cellular and molecular basis of immune tolerance mechanisms and failure. We study the phenotype of immune pathology and use a ‘forward genetics’ approach of taking mouse strains with a genetic predisposition to immune pathology and then work out how this is controlled and why those genetic variations cause pathology.
Our research focuses on tolerance against autoantigens and allergens. Why is tolerance lost at the initiation of disease and how can it be restored? Special emphasis is put on the role of regulatory cells, costimulatory signals and suppressive cytokines. We use several animal models (autoimmune encephalitis, allergic asthma and colitis) and also study these aspects in human subjects with allergic and autoimmune diseases.
• Study of the regulation of the immune response to Streptococcus pneumoniae
• Immunodeficiencies, with particular interest on innate immunity
• Autoimmunity, with particular interest on serological markers
Our research addresses the immune mechanisms underlying organ allo- or xenograft tolerance or rejection, and the mechanisms underlying immune-mediated graft-versus-tumor effects of allogeneic bone marrow transplantation and post transplant adoptive cell therapy. The lab also investigates the development of new immunosuppressive small molecules in collaboration with the Laboratory of Medicinal Chemistry.
The staff members are dedicated clinicians involved in the patient care of the General Internal Medicine Department, including Emergency Care and Intensive Care. Hence, the research efforts have tight links with clinical care and provide a dynamic interplay between bench and bedside. Examples of topics include: hepatic critical care: detoxification devices and hemodynamics; cholestasis in the critically ill; clinical trials in sepsis, vasculitis syndromes and noninfectious inflammatory disorders; and fever of unknown origin.

The Abdominal Transplant Surgery Lab conducts the following translational research projects:
Development of tolerogenic protocols to promote graft acceptance after intestinal transplantation (in cooperation with the Laboratory of Experimental Transplantation).
Prevention/amelioration of ischemia reperfusion injury after liver, kidney, intestinal transplantation by improved preservation strategies (among them machine perfusion) and/or biological intervention.
The lab uses models of transplantation and/or ischemia reperfusion injury in rats and pigs. We perform and participate in randomized clinical trials.
