Characteristics of Treg in gut. A Tregs suppress effector cells and antigen-presenting cells via surface protein and cytokine. B Helios+Gata3+Foxp3+Tregs (thymic Tregs: tTregs), Helios−Rorγt+Foxp3+Tregs (peripheral Tregs: pTregs), Helios−Rorγt−Foxp3+Tregs (peripheral Tregs: pTregs) in small intestine (left) and colon (right). The percentage of each population in total Tregs was listed below. C Schema of generation of peripheral Tregs in gut
