Tfr cells lack IL-2Rα but express decoy IL-1R2 and IL-1Ra
Follicular regulatory T (T fr) cells from lymph node germinal centers control follicular helper T (T fh) cell–dependent B cell activation.These scarce cells, often described and purified as CD25 + cells, are thought to be derived from thymic regulatory T (T reg) cells.However, we observed that mouse T fr cells do not respond to interleukin-2 (IL-2), unlike T reg cells.

Metabolic control of T FH cells and humoral immunity by
Abstract. T follicular helper (T FH) cells are crucial for B cell-mediated humoral immunity 1.Although transcription factors such as BCL6 drive the differentiation of T FH cells 2,3, it is unclear whether and how post-transcriptional and metabolic programs enforce T FH cell programming. Here we show that the cytidine diphosphate (CDP)-ethanolamine pathway …
