Figure 6.

Scientific figure divided into panels A through M comparing outcomes between low and high Blautia abundance in feces. Panels A, B, and H-K depict bar and dot plots showing significant differences in microbial abundance, lung injury score, and T cell populations. Panel C shows two chest CT scans with increased lung pathology in the high Blautia group. Panels D, E, F, and G display flow cytometry plots for CD3+, CD8+, granzyme B, IFN-gamma, and CD4+ T cells between groups. Panel M presents a scatter plot with significant positive correlation between Blautia abundance and CD8+ T cell percentage.

Blautia-Potentiated CD8+ T-Cell Recruitment Attenuates SI-ALI. (A) Abundance of Blautia in fecal specimens from SI-ALI patients. (B, C) Lung injury scores and chest CT manifestations of SI-ALI stratified by fecal Blautia levels. (D-K) Flow cytometric analysis of peripheral blood T lymphocytes in SI-ALI patients stratified by fecal Blautia abundance: CD3+CD8+ populations, CD3+CD4+ populations, IFN-γ+CD8+ subsets, and Granzyme B+CD8+ subsets. (L) Spearman correlation analysis between fecal Blautia levels and the count of peripheral blood CD8+ T cells. * P<0.05; ** P<0.01; *** p<0.001; **** p<0.0001.
