WebBackground: Migration of T cells, including regulatory T (Treg) cells, into the secondary lymph organs is critically controlled by chemokines and adhesion molecules. Webcells from Il2rg-/-mice all exhibit an activated phenotype as illustrated by high CD69 and low CD62L expression. CD69 expression is reduced to background levels, while CD62L remains high, on CD8+ T cells from Stat5b-CA x Il2rg-/-mice, indicating that the Foxp3+ Treg cells generated in those mice are capable of blocking T cell activation.
