IRF7 and infection: Analysing the dose dependence of Socs1 and Ifnα/β mRNA peaked and integrated values in WT, Mavs‐/‐, Sting‐/‐ or Caspase1‐/‐ pDCs, we found that in low‐dose YM infection (eg YM = 0.1), there were similar production of MyD88‐IRF7‐dependent type I IFN response, while diverse Socs1 expression among all types pDCs (Figure 3B‐C).
