IL-2-Producing Tfh Cells Sustain Treg Cell Homeostasis and Immune Tolerance in the Gut
Follicular helper T (TFH) cells are well known for their role in supporting B cell responses. Here, we identify a critical B cell-independent function for TFH cells in sustaining regulatory T (Treg) cells within gut-associated lymphoid tissues (GALT). We demonstrate that TFH cells produce interleukin-2 (IL-2) at the T...
