Outline of Final Research Achievements |
We previously reported that low-dose IL-2 can induce immune-tolerance with the increase of Treg. However, Treg increase might reduce GVL effect. Therefor, we need to develop the technique to regulate Treg homeostasis during low-dose IL-2 therapy. In this study, our murine study and human subject analysis clearly demonstrated that PD-1 signaling has indispensable role for Treg homeostasis during IL-2. Our results might provide important information for the development of the Treg-based immune therapy for patients after HSCT.
