Correlation between total memory or naïve Tregs with PD1<sup>+</sup> CD95<sup>+</sup> cells.

<p>At week36% total memory CD45RO<sup>+</sup>CD25<sup>+</sup>CD127<sup>low</sup>FoxP3<sup>+</sup> (A) or naïve CD45RO<sup>-</sup>CD25<sup>+</sup>CD127<sup>low</sup>FoxP3<sup>+</sup> (B) were measured by flow cytometry and then correlated with %PD-1<sup>+</sup>CD95<sup>+</sup>CD4<sup>+</sup>. Correlations were calculated using spearman correlation coefficients (Prism 5.0, version 5.0d). P values were considered significant when < 0.05.</p>
