Primary immune deficiencies unravel the molecular basis of immune response.
Primary immune deficiencies (PID) represent inborn errors of immunity. Over the years, detailed analysis of the clinical and laboratory features associated with these unique and rare disorders have shed light on the complex array of signals and processes that govern development and activation of the immune system. While the first examples of PID pertained to severe defects in lymphoid development, more recently a variety of gene defects have been identified in humans that do not compromize the ability to generate lymphocytes, but rather result in profound immune dysregulation. In many cases, identification of the molecular and cellular bases of PID has preceeded development of animal models by gene targeting. Finally, since the very first cases reported in humans, PID have also represented a unique tool to investigate the efficacy of novel therapeutic approaches (from molecular therapy to hematopoietic stem cell transplantation to somatic cells gene therapy), that have been applied or may apply to a variety of more common human diseases.
