STING1 and cytomegalovirus infection: Interestingly, while the overall RNA expression of STING was rather low in moDCs (Supplementary Fig. 7c), protein analysis by flow cytometry of the three moDC subsets revealed that intrinsic levels of STING (in mock treated cells) were lower in M2 than in M1 and M3 moDCs (Fig. 7i and Supplementary Fig. 7d), which correlated with the susceptibility of the three moDC subsets to HCMV infection (Fig. 7h), highlighting a potential link between intrinsic levels of STING expression and the start of IE gene expression.
