^*Elimination rates for naive and memory T cells were calculated using nonlinear regression analysis of the washout phase in normal and SIV-infected macaques. Data are presented as the mean ± SD for normal and SIV-infected animals. 

^†Significantly different than in normal animals, P < 0.01 (Mann–Whitney U test). 

^‡P < 0.05 (Mann–Whitney U test).
