In vitro activation of DC by transfection with single stranded viral or synthetic RNA containing 5' phosphates

signalling dataset

We have obtained data from our studies demonstrating that DC and other cell types can be activated in vitro by transfection with single stranded viral or synthetic RNA containing 5’ phosphates. This form of activation is mediated by the helicase RIG-I and leads to production of high levels of type I IFNs. Notably, this observation may explain the ability of mRNA transfection to activate DC for immunisation protocols: such RNA, even if synthesised in the presence of cap analog, always contains a certain percentage of uncapped molecules bearing 5’ tri-phosphates.
