Purified pDCs (A) and cDCs (B) were treated for 1h with TOFA (doses expressed in μM), an inhibitor of acetyl-CoA carboxylase-α, then stimulated with TLR9 agonist CpGA 5μg/ml. Activation was measured after 24h by CD86 expression via flow cytometry. pDCs were gated for B220+CD11c+CD11b-. cDCs were gated for B220-CD11c+CD11b+. Viability of cells (C) is expressed as % of cells negative for the Fixable Viability Dye. Results are shown as the mean ± SEM, from 5 independent experiments. Significance was calculated by one-way ANOVA and multiple comparisons post-hoc correction test, and P-values marked in the figures as * P<0.05, ** P<0.01, *** P<0.001 and **** P<0.0001 were considered significant.
