Blimp1 tfh
WebBlimp1 is required for the differentiation of B cells and T cells, and it has been identified as an essential regulator of T-cell homeostasis and activation.28–30 It has been shown that loss of Blimp1 could double the propor-tion of Tfr cells without any alteration in the proportion of Tfh cells.24 If deficiency of Blimp1 results in greater ... WebFeb 17, 2015 · KLF2 promotes expression of the trafficking receptor S1PR1, and S1PR1 downregulation is essential for efficient Tfh cell production. However, KLF2 also induced expression of the transcription factor Blimp-1, which repressed transcription factor Bcl-6 and thereby impaired Tfh cell differentiation.

WebApr 1, 2024 · Targeted by Bcl6, Blimp1 accomplishes positive expression of T FH -associated proteins via a repression-of-repressor circuit. The upregulation of CXCR5 and PD-1 in T FH cells is controlled by the Bcl6-directed repression of Blimp1.
WebShen et al. identify Blimp1 as a critical transcription factor for the proper positioning and stable expression of the suppressive activity of TFR cells that control GC responses. In the absence of Blimp1, unstable TFR cells prematurely migrate into the GC and differentiate into TFH-like cells to promote dysregulated GC responses. WebApr 7, 2024 · PRDM1 (B lymphocyte–induced maturation protein 1, BLIMP1) and CTLA4 expression were not only greatest in Tfr but also high in CD25 hi Tfh cells. Most transcripts elevated in CD25 hi Tfh cells encoded activation and/or cell cycle markers (fig. S3).
WebApr 15, 2013 · As a result, CXCR5 + Tfh cells in Tfh-recipient μMT mice expressed Blimp1 at a much higher level compared with Tfh cells in B6 mice . The rigid requirement of Ag presentation, initially by DCs and followed by B cells, is one of the unique features for Tfh differentiation ( 2 , 6 , 9 , 40 , 42 , 43 ). WebMar 8, 2024 · In activated CD4 + T cells, Tcf1 and Lef1 act upstream of the Bcl6-Blimp1 axis to direct differentiation of follicular helper T (Tfh) cells, and prevent diversion of Tfh to IL-17-producing cells. In parallel, T-bet, together with Eomes or Blimp1, ensures proper induction of the cytotoxic program in CD8 + effectors elicited by acute infection ...
WebThe regulation of Tfh cell differentiation by Blimp1 is Bcl6-dependent while Blimp1 controls Tfr cell differentiation independent of Bcl6 . One mechanism for Bcl6-independent Blimp1 activity may relate to regulation …
