Administration of hIL-2 does not induce Foxp3 expression in Tconv during xeno-GVHD. (A) NSG mice engrafted with hPBMCs (10 x106) were injected with either hIL-2 (1 x 105 IU, n=5) or PBS (n=6) on day 11, 12, and 13. CD4+ T cells from a representative mouse spleen on day 14 and summary data on CD25, Foxp3 and Helios expression from all recipients are shown. (B) IL-2, IFNγ, and granzyme B production by cells in panel A were determined by flow cytometry and summary IL-2 data from all recipients is shown. Plots are representative of one of two independent experiments.***p<0.0005, ****p<0.0001, two-way ANOVA with Tukey’s multiple comparisons test.
