DHX9 or DHX36 knockdown by siRNA inhibited cytokine release in human GEN2.2 cell line (leukemic pDC cells) in response to CpG-ODN or to HSV but not to RNA viruses. Furthermore, knockdown of DHX36 diminished the nuclear localization of IRF7 in CpG-A-stimulated cells, while knockdown of DHX9 inhibited nuclear localization of NF-kappaB p50 in response to CpG-B. Thus, DHX36 and DHX9 are thought to trigger MyD88-dependent IRF7 and NF-kappaB activation respectively [Kim T et al 2010].
DExH/D-box helicase (DHX9)-mediated sensing of CpG-B trigger downstream signaling to NF-Îșappa B. Knockdown of DHX9 expression by RNA interference in the CpG-B-treated human plasmacytoid dendritic cell line Gen2.2 inhibited nuclear localization of p50 (NF-kappa-B1) subunit of NF-Îșappa B complex (Kim T et al. 2010).
DNA-dependent activator of IRFs/Z-DNA binding protein 1 (ZBP1 or DAI) recruits RIP1 and RIP3 through RIP homotypic interaction motifs to activate NF-kappaB (Rebsamen M et al. 2009).
Detection of cytosolic DNA requires multiple and possibly redundant sensors leading to activation of the transcription factor NF-kappaB and TBK1-mediated phosphorylation of the transcription factor IRF3. Cytosolic DNA also activates caspase-1-dependent maturation of the pro-inflammatory cytokines interleukin IL-1beta and IL-18. This pathway is mediated by AIM2.
