Brief Summary

It is assumed that gut inflammation and lesions characterizing flares of Crohn's disease (CD) result from an aberrant T-cell mediated immune responses characterized by a complex balance between peripheral and lamina propria regulatory and effector T cell subsets. Because most of CD patients who undergo a surgery experienced a postoperative endoscopic recurrence of the disease (70 % at one year) leading to a clinical recurrence (10 % per year), the "model" of postoperative recurrence in CD represents a privileged situation that mimicks what happens in the gut of CD patients in clinical remission before the occurrence of further flares. It is likely that the same factors which underlie the immunopathogenesis of CD at its early stages also contribute to disease recurrence in the postoperative setting. Indeed, the postoperative state is performed for intent of disease remission and this situation represents probably an ideal setting to investigate the dynamics of most of T cell subsets in the peripheral and mucosal compartments because one may argue that removal of the diseased segment of bowel resets the disease to its earliest phases, providing an interesting window to better understand which T cell subsets predispose to disease recurrence. That is the reason why this model will be used in the present project i) to understand better the immunopathogenesis of CD relapse; ii) to identify novel and promising immune cell-associated biomarkers capable to predict relapse of the disease and finally iii) to identify potential specific therapeutic target associated with T cell subsets involved in the initiation of disease.
