Comparison of the two groups of animals showed that treatment with IL-7 did not induce significant increases in the levels of SIV plasma viremia at any time during the acute phase of infection and the follow-up period, including the peak of viral replication, the viral set point and the AUC, with the only exception of the earliest time point analyzed (day 4 post-infection; p = 0.043 for the comparison between the two groups of animals by Wilcoxon rank sum test) (Figure 2A). Here, IL7 is linked to infection.
