Higher frequency and ratios of Vβ11⁺ tTregs to Tcons in lymphoid organs of PTCy-treated chimeras. (A) Representative flow plots of Vβ11⁺ Tcons, tTregs, and pTregs from the MLNs of control and PTCy-treated chimeras. (B) Ratio of Vβ11⁺ Tcons to Vβ11⁺ tTregs (left panel) and pTregs (right panel) in spleens, CLNs, and MLNs of control and PTCy-treated chimeras. Data shown are representative of 2 independent experiments with at least 5 animals per group and were analyzed on day +28 post-alloBMT. *P < .05.
