CD80 and infection: Following the stimulation of BM-DCs with either Rad-GBS or Che-GBS at various multiplicities of infection (MOIs) for 12 h, the mean fluorescence intensity (MFI) of several phenotypic maturation markers, including CD80 (p < 0.05), CD86 (p < 0.05), and MHCII (p < 0.05), was considerably increased upon stimulation with Rad-GBS (MOI = 1, 10, and 100), respectively (Figure 2A–D and Supplementary Figure S2).
