Figure 3. mtDNA stress potentiates viral resistance.
a, Viral GFP expression in MEFs infected with HSV1-GFP or VSV-GFP at MOI 0.5 for 24 hrs. b, MHV68-GFP abundance in MEFs infected at MOI 0.5. c, LCMV Armstrong gene expression 4d after i.v. infection of WT and Tfam+/− mice; n=4. d-f, Nucleoid area (d) or ISG expression (e) of MEFs exposed to ddC for 96 hrs. ddC-exposed MEFs were infected with HSV1-GFP or VSV-GFP at MOI 0.1 and imaged after 24 hrs. Error bars represent ± s.e.m. of triplicates (b,e) or quadruplicates (c) and all panels are representative of three independent experiments. **=p<0.01, ***=p<0.001.
