TRAF6 and eosinophilic gastroenteritis: In our study, we found that lower expression of TRAF6 in the intestinal tissues of EGE is negatively correlated with peripheral blood IL-10 levels, which probably indicates that the deficiency of TRAF6 in the intestinal tissues of patients with EGE tends to afflict the mucosal barrier of GI tract and then causes a Th2-dominated immune response which is closely related to the higher expression of peripheral IL-10.
