In the SG levels of IFN-γ and IL-10 were both low at these early times (MCMV arrives in the SG between days 7 and 14 after i.n. infection.22 SGs of WT mice produced an average of 127 pg/mL of IFN-γ and 286 pg/mL of IL-10, which were reduced by 2.3x and 3.8x respectively in BLT1−/− mice (Fig. 3E). Here, IFNG is linked to infection.
