Efficiency of IL-7-dependent signaling in different CD4⁺ T-cell subsets^a

Subset	Re ratio			P
	HD	VIR	HAART	HD vs VIR	VIR vs HAART
NTreg	23.38	34.33	23.23	<0.05	<0.05
MTreg	30.02	32.97	32.55	NS	NS
Nv	8.32	13.52	9.08	<0.001	<0.05
Mem	10.45	15.67	11.96	<0.005	<0.01

^aThe R_e ratios of ΔpSTAT5 MFI to CD127 MFI were computed for four CD4⁺ T cell subsets after high-dose IL-7 stimulation and compared between healthy donors (HD), viremic patients (VIR), and treated patients (HAART). Median values for R_e ratio are indicated. Differences between groups were evaluated by the Mann-Whitney U test. P values of <0.05 are reported. NS, not significant. All P values for HD versus HAART were not significant.
