WebApr 4, 2024 · Moreover, IRF8 was detected as a novel fusion partner of IGH in DLBCL, 39,40 and this fusion resulted in higher IRF8 expression levels. 39 In a mouse model of the IGH-IRF8 fusion, this deregulation resulted in lower survival of these mice compared with the WT control; however, no increased incidence of B-cell lymphoma was observed. 41 IRF8 is ... 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.
