Research focus The team focuses on different aspects of the human immune response and on how the underlying mechanisms of immunity are linked with the development of disorders and pathologies. The main objectives are addressing i) new key events in myeloid cell signaling, describing the role of the Calcineurin–NFAT axis in the control of myeloid cell response to pathogens; (ii) novel important roles of immune response in the progression of human sepsis; (iii) the research in the field of immune senescence, addressing the immunosenescent phenotype in a number of cohorts of patients with various disorders and in child cancer survivors; iv) the development of 3D models of human mucosal tissues to mimic and study the immunocompetence of these complex microenvironments. Our tight collaboration with clinicians creates the opportunity to perform pre-clinical research with a strong translational approach, filling the gap between bench and bedside.

Other selected results
The CMI has published series of papers (Mucosal Immunology, Cell Reports, Stem Cells, EMBO Molecular Medicine and Blood) showing new important mechanism of immune protection against pathogens and myeloid cells development
The CMI has shown that immunosuppressive drugs (such as Cyclosporine A or Tacrolimus) affect function of calcineurin NFAT signaling pathway in myeloid cells and their precursors, which causes dysregulation of myelopoiesis and increased susceptibility to infections. These results are important for understanding the complications of immunosuppressive therapies.
