WebB cells require IRF4 to mediate chronic transplant rejection. IRF4 ablation in B cells abrogates allogeneic B cell responses and may also inhibit the ability of B cells to prime … WebApr 8, 2024 · IRF4 works in a dose-dependent manner in B cells, at low levels triggering the expression of the enzyme activation-induced deaminase (AID), thus driving somatic hypermutation and class switch recombination, and at high levels allowing the expression of Blimp-1 ( 21, 27 ), therefore being crucial for PC differentiation. citric acid endothermic reaction

WebSep 29, 2024 · In vitro Stimulation of Human B Cells Generated Populations With Distinct IRF4 and Pax5 Expression Levels To evaluate PC differentiation in vitro at the transcription factor level, we next assessed the expression of IRF4 and Pax5. WebDec 10, 2024 · IRF4 is implicated in B cell malignancies, acting both as tumor suppressor and as tumor oncogene in different types of precursors and mature B cell neoplasia. Here, we summarize the complexity of IRF4 functions related to different DNA-binding affinity, multiple IRF4-specific target DNA motif, and interactions with transcriptional partners. WebInterferon regulatory factor 4 (IRF4) rearrangement is commonly detected in patients with a range of lymphoproliferative malignancies, including myelomas, large B cell lymphomas and low-grade B cell neoplasms. However, IRF4 rearrangement is generally a relatively rare finding in these latter two cancer types. citric acid facts
