After cART interruption , a decrease in T-cell receptor excision circles ( P < 0.001 ) and naive CD8 T cells ( P < 0.001 ) , an increase in IL-7 and expression of CD127 on naive and memory CD4 T cells ( P = 0.028 , P = 0.088 , and P = 0.04 , respectively ) , and a significant decrease in CD127 on naive and memory CD8 T cells ( P = 0.01 , P = 0.006 , respectively ) were observed .
