Novel Role for Host Immunostimulatory RNA in Antiviral Immune Defense
PROJECT SUMMARY Work from many laboratories has established that DNA sensors – both membrane-localized Toll-like receptors (e.g. TLR9) and intracellular DNA sensors (e.g. cGAS) – sense herpesvirus infection. In striking contrast, our knowledge about the physiologic relevance of cytoplasmic RNA sensors of the RIG-I-like receptor (RLR) family in the detection of herpesviruses, such as herpes simplex virus type 1 (HSV-1), is rudimentary. The proposed study builds on a recent discovery by the Gack laboratory that RIG-I plays a crucial role in the detection and restriction of HSV-1 infection, where RIG-I and intracellular DNA sensors act in a temporal manner. Furthermore, we identified that…
