Fig 4. Correlation between total memory or naïve Tregs with PD1⁺ CD95⁺ cells.

At week36% total memory CD45RO⁺CD25⁺CD127^lowFoxP3⁺ (A) or naïve CD45RO^-CD25⁺CD127^lowFoxP3⁺ (B) were measured by flow cytometry and then correlated with %PD-1⁺CD95⁺CD4⁺. Correlations were calculated using spearman correlation coefficients (Prism 5.0, version 5.0d). P values were considered significant when < 0.05.
