Suppressor activity of Treg in R0 and R cultures^a.

aThe data are means±SD of percent suppression measured in co-cultures of proliferating autologous responder cells with Treg generated in R0 or R cultures. R cultures were set up with 1 nM RAPA. Responder cells were either CD4+CD25neg or CD8+CD25neg. The co-cultures were established with cells obtained from 10 NC. The responder cell to Treg ratios were 1∶1 in all cultures. bThe p values are for the differences in the % suppression between Treg in the R0 and R cultures.
