Outline of Final Research Achievements |
T-follicular regulatory T-cells (Tfr) have a critical role for controlling antibody responses by germinal center B-cells. I have discovered that Tfr can differentiate into a mature germinal center resident subset characterised by a lack of expression of the high affinity IL-2 receptor, CD25. This allows the cells to upregulate the IL-2 inhibited transcription factor BCL-6 and travel to the germinal center to suppress B-cells. These cells can be found in both mice and humans and unlike most regulatory T-cells (Tregs), of which Tfr are a subgroup, are inhibited by the presence of IL-2. This demonstrates a fundamental split in regulatory T-cells into IL-2 dependent Tregs and IL-2 independent Tfr and has important implications for many clinical trials using IL-2 to control Treg function.
