Cutting Edge: memory regulatory t cells require IL-7 and not IL-2 for their maintenance in peripheral tissues.

Gratz IK, Truong HA, Yang SH, Maurano MM, Lee K, Abbas AK, Rosenblum MD (2013) Cutting Edge: memory regulatory t cells require IL-7 and not IL-2 for their maintenance in peripheral tissues. J Immunol 190(9):4483-4487. doi: 10.4049/jimmunol.1300212

Summary: Recently a new class of regulatory T cells (mTregs) were found that persist in non-lymphoid tissues and are involved in suppressing autoimmune responses. In order to examine the roles that IL-2 and IL-7 play in the development and regulation of mTregs, the authors used genetic deletion, adoptive T-cell transfer, and in vivo neutralization techniques. 5 μg of intravenous OX7-SAP (Cat. #IT-02) per mouse was used to deplete CD90.1-positive cells during the adoptive transfer experiment. It was found that IL-7 is essential for the steady-state maintenance of mTregs in skin.
