WebMay 5, 2024 · Studies using reporter mice have demonstrated that IRF8 is expressed at high levels in all B cell subpopulations except the plasma cells (PCs) ( 17 ). PU.1 is also constitutively expressed in BM-developing B cells and splenic naïve B cells ( 18 ). WebIRF8 (interferon regulatory factor 8; OMIM 601565, Chr. 16) is a transcription factor that is exclusively found in cells with hematopoietic lineage and is highly expressed in plasmacytoid dendritic cells ( Sichien et al., 2016 ).

WebAug 8, 2024 · It has been demonstrated that the response of B cells to CpG is largely unaffected by IRF8-deficiency in NZB (New Zealand Black) mice. We found that production of IL-6 and IL-10 by Irf8 −/− B cells were comparable to that of WT. However, reduced secretion of TNF-α in IRF8-deleted B cells determined the partial TLR9 signaling defect. WebMar 30, 2024 · IRF8 is a transcription factor that belongs to one of the nine family members of interferon regulatory factors (IRF). IRF8 has a DNA binding domain (DBD; 120 aa) of the helix-turn-helix type and an IRF association domain (IAD) that serves as a recruitment module for other transcription factors. flippee loud house
