DHX15 senses double-stranded RNA in myeloid dendritic cells.
Many members of the DEXD/H box helicase family play important roles in the innate immune system against viral infection. Therefore, we isolated dsRNA complex in myeloid dendritic cells. We found that DHx15, a DEXDc helicase family member, is one of the components of this complex. Knockdown of DHX15 expression by short hairpin RNA efficiently reduced the ability of myeloid dendritic cells to pro...
متن کاملInterferon, double-stranded RNA, and protein phosphorylation.
We reported earlier that the addition of double-stranded RNA and ATP increases the endonuclease activity more in an extract of Ehrlich ascites tumor cells which have been treated with an interferon preparation than in a comparable extract from control cells. We report here that the addition of double-stranded RNA to an extract from Ehrlich ascites tumor cells which have been treated with an int...
متن کاملPoliovirus single-stranded RNA and double-stranded RNA: differential infectivity in enucleate cells.
The ability of poliovirus virion RNA and double-stranded RNA (replicative form) to replicate in enucleate mouse L cells was investigated. Virion RNA replicated successfully in the absence of the cell nucleus, whereas replicative form infection did not produce any detectable progeny in enucleate cells. The results provide direct evidence of a nuclear requirement early in the infection initiated ...
متن کاملBoth yeast W double-stranded RNA and its single-stranded form 20S RNA are linear.
Most yeast strains carry a cytoplasmic double-stranded RNA (dsRNA) molecule called W, of 2.5 kb in size. We have cloned and sequenced most of W genome (1), and we proposed that W (+) strands were identical to 20S RNA, a single-stranded RNA (ssRNA) species, whose copy number is highly induced under stress conditions. Recently it was proposed that 20S RNA was circular (2). In this paper, however,...
متن کاملMaturation, Activation, and Protection of Dendritic Cells Induced by Double-stranded RNA
The initiation of an immune response is critically dependent on the activation of dendritic cells (DCs). This process is triggered by surface receptors specific for inflammatory cytokines or for conserved patterns characteristic of infectious agents. Here we show that human DCs are activated by influenza virus infection and by double-stranded (ds)RNA. This activation results not only in increas...
