In this collaborative project, Chris and Hendrik found that long-term delivery of RIG-I ligand leads to cytostasis. Surprisingly, unlike found for other innate immune stimuli (e.g. LPS) persistent activation of the RIG-I pathway does not lead to tolerance. We hypothesize that this system recapitulates the situation in HCV-infected livers, which requires constant re-infection of cells in order to persistently propagate the virus. A beautiful story – which you can read here.

Congratulations to Philipp Hubel and co-authors – our work on the innate immune network got published in Nature Immunology!
The body’s defense strategies against viral infections are as diverse as the attacks themselves. We conducted a survey to systematically investigate the interactions of interferon-stimulated genes (ISGs), which are at the center of coordinating the antiviral immune response. Through integrating data obtained by affinity purification followed by mass spectrometry (AP/MS), published datasets and functional validation experiments, we found many unknown interactions of ISGs, which sheds light on the overall organization of the innate immune system.
