Dynamic regulation of T Follicular Regulatory cell responses by interleukin 2 during influenza infection #MMPMID28892471
Nat Immunol 2017[Nov]; 18 (11): 1249-60 PMID28892471show ga
Interleukin 2 (IL-2) promotes Foxp3+-regulatory T (Treg) cell responses, but inhibits T follicular helper (TFH) cell development. However, it is not clear how IL-2 affects T follicular regulatory (TFR) cells, a cell type with properties of both Treg and TFH cells. Using an influenza infection model, we demonstrated that high IL-2 concentrations at the peak of the infection prevented TFR cell development by a Blimp-1?dependent mechanism. However, once the immune response resolved, some Treg cells down-regulated CD25, up-regulated Bcl-6 and differentiated into TFR cells, which then migrated into the B cell follicles to prevent the expansion of self-reactive B cell clones. Thus, unlike its effects on conventional Treg cells, IL-2 inhibits TFR cell responses.
