Figure 2From: Nasally administered Lactobacillus rhamnosus strains differentially modulate respiratory antiviral immune responses and induce protection against respiratory syncytial virus infectionEffect of lactobacilli on respiratory immune cells populations. Effect of viable (Lr05) or heat-killed (HkLr05) Lactobacillus rhamnosus CRL1505 and viable (Lr06) or heat-killed (HkLr06) L. rhamnosus CRL1506 nasal administration on CD3+CD8+IFN-γ+, CD3+CD4+IFN-γ+ and CD3+CD4+IL-10+ T cells and CD11c+CD11blowCD103+ and CD11c+CD11bhighCD103- dendritic cells from lung. Lr05, Lr06, HkLr05 or HkLr06 were nasally administered to different groups of mice for 2 consecutive days at a dose of 108 cells/mouse/day and lung immune cells were studied on day 3. The results represent data from three independent experiments. Different letters indicate significant differences (P < 0.05).Back to article page
