Interferons (IFNs) activate cell-intrinsic defence mechanisms to fight infections. The innate immune response to infections overlaps and cooperates with cellular stress signalling governed by the mitogen-activated protein kinase (MAPK) p38. Laura Boccuni in the group of Thomas Decker unravelled the molecular mechanism how macrophages merge the IFN JAK-STAT and the stress p38 MAPK pathways to enhance the beneficial but also the detrimental effects of the innate and inflammatory responses. With the exception of one, all SFB groups contributed to this SFB-financed publication.
