P. zoogleoformans promotes the accumulation of IFNγ⁺ T cells in mouse lungs. Periodontitis was performed 14 days before the induction of PH. Samples were analyzed 7 days after PH induction. a, b Representative flow cytometry plots of CD4⁺IFNγ⁺ T cells a and quantification of the percentage of CD45⁺ cells and number of CD4⁺IFNγ⁺ T cells b in lungs. n = 9:6. c, d Representative flow cytometry plots of CD8⁺IFNγ⁺ T cells c and quantification of the percentage of CD45⁺ cells and number of CD8⁺IFNγ⁺ T cells d in lungs. n = 9:6. e, f Representative flow cytometry plots of CD4⁺IFNγ⁺ T cells e and quantification of the percentage of CD45⁺ cells and number of CD4⁺IFNγ⁺ T cells f in cervical lymph nodes (cLNs). n = 8:7. g, h Representative flow cytometry plots of CD8⁺IFNγ⁺ T cells g and quantification of the percentage of CD45⁺ cells and number of CD8⁺IFNγ⁺ T cells h in cLNs. n = 8:7. Data are presented as mean ± SEM. Student’s t test b, d, f, h was used for statistical analysis. ns not significant. *P < 0.05. **P < 0.01
