Correlation between relative frequencies of CD4+FoxP3 T cells in CLN and spleen.

<p>Each point represents one mouse, placed as a function of relative CD4+FoxP3 T cell frequencies in CLN and spleen (cf legend to <a href="http://www.plosone.org/article/info:doi/10.1371/journal.pone.0085923#pone-0085923-g005" target="_blank">Fig. 5</a>). Black dots, PBS (control without bacteria or DSS); grey triangles, DSS (DSS only, without bacteria); light grey squares, 327+DSS (DSS plus Lb CNRZ327). The grey line describes the linear relationship between the frequencies of CD4⁺Foxp3⁺ cells in the spleen and in the colon (R² = 0.415).
