Irf8 pdc
WebIRF8-/- mice are deficient in both pDC and CD8a+ DC populations. CD8a- DC are present in normal numbers in IRF8-/- mice but fail to mature upon Toll-like receptor signaling and are functionally impaired in response to in vivo microbial stimulation. IRF8 deficiency does not affect the frequency or viability of DC precursors and as a result ... WebPlasmacytoid dendritic cells (pDCs) are a unique subset of dendritic cells that circulate in the blood and peripheral organs and rapidly secrete large amounts of type I interferons (IFNs) following activation. They are …

WebMar 8, 2024 · The rare pDC disorder blastic pDC neoplasm (BPDCN) is associated with myeloid malignancies in 20% of cases. For example, although BPDCN and chronic monomyelocytic leukemia (CMML) have divergent mutational landscapes, they share BM TET2 mutations that skew hematopoiesis toward monocytes and DCs ( Batta et al., 2024 ). WebIRF8 plays an important role in the differentiation of mononuclear phagocytes from the HSCs. People with homozygous IRF8 deficiency (K108E mutation) ( Hambleton et al., 2011) or compound heterozygous R83C/R291Q mutation demonstrate a distinct lack of pDCs as well as cDC1 subset ( Bigley et al., 2024 ).
WebIRF8 seems to act as a positive regulator of IFN and pro-inflammatory signaling in the murine system. In BM-derived pDCs and conventional DCs, IRF8 was shown to be involved … WebInterferon regulatory factor 8 (IRF8) is a transcription factor, which acts in hematopoiesis as lineage determining factor for myeloid cells, including dendritic cells (DC). Autosomal recessive or dominant IRF8 mutations occurring in patients cause severe monocytic and DC immunodeficiency.
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 ).
