Our new manuscript, by lead author Gargi Mishra, shows that the IFN-I locus in pDCs is poised for rapid interferon production, as PU.1 and IRF8 establish an open chromatin architecture. #Immunology #Interferons #InnateImmunity #Epigenetics

Lineage-specific chromatin poising enforced by ETS-IRF composite elements determines the divergent interferon responses of plasmacytoid dendritic cells and epithelial cells
Plasmacytoid dendritic cells (pDCs) produce robust type I interferons (IFN-I) within hours of viral sensing, while epithelial cells at mucosal surfaces mount a delayed response dominated by type III i...
