Transcription profiling of mouse Splenic CD4+CXCR5+ T (TFH) cells

ABSTRACT: After activation, CD4+ helper T (Th) cells differentiate; into distinct effector subsets. Although chemokine; (C-X-C motif) receptor 5-expressing T follicular; helper (Tfh) cells are important in humoral immunity,; their developmental regulation is unclear. Here we; show that Tfh cells had a distinct gene expression; profile and developed in vivo independently of the; Th1 or Th2 cell lineages. Tfh cell generation was regulated; by ICOS ligand (ICOSL) expressed on B cells; and was dependent on interleukin-21 (IL-21), IL-6,; and signal transducer and activator of transcription; 3. However, unlike Th17 cells, differentiation of Tfh; cells did not require transforming growth factor; b (TGF-b) or Th17-specific orphan nuclear receptors; RORa and RORg in vivo. Finally, naive T cells activated; in
