Characterization of T cells populations in response to SR.

<p>T cells were characterized after 18h, in the acute and in the chronic model. They were identified as CD4⁺ or CD8⁺, then CD103 expression on T cell subsets was verified in WT samples using <i>Cd103</i>^<i>-/-</i> mice as control for CD103 staining. Number of total lung <b>A)</b> CD4⁺ T cells and <b>B)</b> CD8⁺ T cells. <b>C)</b> Number and <b>D)</b> % of CD4/CD103⁺ T cells. <b>E)</b> Number and <b>F)</b> % of CD8/CD103⁺ T cells. For Tregs analysis CD25⁺Foxp3⁺ on lung CD4⁺ T cells was verified using FMO controls. <b>G)</b> % and <b>H)</b> number of Tregs. Results were obtained from 2 pooled experiments; n = 6–12 mice/group. * = p < 0.05 for unpaired t-test. † = p < 0.05 with multi-comparison test.
