WebMar 20, 2024 · It has been shown that IRF8 and SPI1 may contribute to BCL6 induction in antigen-engaged pre-GC-B cells, while IRF4 and PRDM1 repress BCL6 in light zone GC-B cells (16, 48). Moreover, the binding of BCL6 to its own 5′ regulatory region forms an autoregulatory circuit that limits its own expression in GC-B cells (Figure 2C) . WebOur recent work demonstrated that IRF4 and SPIB are epigenetic targets of JAK1 due to H3Y41 phosphorylation, but IRF4 expression is not regulated by STAT3 ( 3 ). These findings along with the above RNA-seq analysis prompted us to investigate whether STAT3 directly targets critical genes in the IFNβ signaling pathway.
