Project context and summary :

Immune responses are conditioned by host genetics as well as environmental stimuli that include disease-causing pathogens but also a diverse community of commensal micro-organisms (bacteria, fungi, viruses). However, we still have little information on how immune reactivity is regulated in normal healthy humans. Knowledge in this arena is critical since it could lead to experimental approaches that might impact on the amplitude and duration of immune responses against pathogenic infections. A better understanding of the regulation of mucosal responsiveness can have a major impact on the development and implementation of future vaccine candidates as well as the regulation of systemic diseases, including metabolic, allergic, autoimmune, and psychiatric disorders, which are now suggested to be associated with the perturbation of the normal commensal microbiota.
