The frequency of Tregs, the frequency of Th17 cells, and Tregs/Th17 ratio are correlated with RAI.

<p>To confirm whether Tregs, Th17 cells and Tregs/Th17 were associated with the liver allograft rejection, we analyzed the correlation between RAI and the frequency of circulating Tregs, the frequency of circulating Th17 cells, and Tregs/Th17 ratio. We found that the Tregs level and Tregs/Th17 ratio had a negative correlation with RAI, whereas the Th17 cell level showed a positive correlation with RAI (<i>P</i><0.01).
