WebIL-23 is a heterodimeric cytokine consisting of the subunits IL-23p19 and IL-12p40, which are connected via a disulfide bond. The main biological function of IL-23 is considered to be stimulation of antigen presentation by dendritic cells (DCs), T cell differentiation towards T helper 17 (Th17) cells and production of IFNγ . WebSep 10, 2024 · IRF5 mediates induction of proinflammatory cytokines such as interleukin-6 (IL-6), IL-12, IL-23 and tumour-necrosis factor-alpha (TNF-α) [ 5, 6], and its recruitment to promoters of inflammatory genes is assisted by the NF-kB p65 subunit RelA [ 7]. IRF5 is a key factor in defining the inflammatory macrophage phenotype.
WebJan 6, 2011 · Interestingly, while Th1 responses in Irf5-/-mice were severely impaired 4 weeks after infection, expression of IRF-5 was not required during the first 2 weeks of infection, since the frequency of IFNγ-producing CD4 + T-cells in Irf5-/-mice was comparable to WT mice.
