IFNAR1 and infection: We observed that Ly6C+CD11b+ conventional DCs (cDCs) as well as PDCA1+CD11b+ pDCs were significantly induced in Stat1-/- and Ifnar-/- mice in frequencies after infection compared to uninfected Stat1-/- mice (Fig 4E–4H), while the DCs were similar between all uninfected mice (S2C and S2D Fig).
