Leukocytes in BALF after adoptive transfer. Eosinophils in the BALF of all CRAAT− mice were significantly increased after cockroach sensitization. This effect was paralleled in all mice that received aPD-1ab. However, the adoptive transfer of Tregs significantly decreased the density of eosinophils to the PBS control level. No adverse effects were seen in the BALF of PBS mice that received adoptive transfer. The data are presented as mean ± SEM of five mice per group. *P < 0.01, **P < 0.001.
