Figure 10. Evaluation of the percentage of CD4⁺, CD8⁺, NK and B cells in all Tat-immunized subjects and after stratification by Tat dose.

(A) Changes from baseline of CD4⁺, CD8⁺, NK and B cells (percentage) for all immunized subjects (n = 78 up to week 20, n = 60 at week 48). (B, C) Changes from baseline of CD4⁺, CD8+, NK and B cells (percentage), stratified by Tat doses. (B) Tat 7.5 µg, n = 38 up to week 20 and n = 30 at week 48; (C) Tat 30 µg, n = 40 up to week 20 and n = 30 at week 48, respectively. The t-Test for paired data was used for the analyses: *p<0.05, **p<0.01.
