Effect of Mixed Probiotics on Ovalbumin-Induced Atopic Dermatitis in Juvenile Mice

Figure 6

Mixed probiotics increased the accumulation of Tregs and enhanced PD-1 expression in SDLNs. Representative flow cytometry plots (a). The frequency of Tregs (b). The frequency of PD-1⁺Tregs (c). The frequency of Helios⁺PD-1⁺Tregs (d). Data are shown as the mean ± SD. ^∗ was for the comparison between the OVA + LK group and OVA group. OVA, ovalbumin. LK, probiotics mixture. PD-1, programmed cell death 1. PD-L1, programmed cell death ligand 1.
