IFN-γ and dual IFN-γ/IL-2 measured by ELIPSOT at Baseline and Day 29.
A sub-study of 22 individuals was conducted to evaluate whether VS411 induced an immunosuppressive effect on T lymphocytes. IFN-γ responses specific for Gag (A) and for Rev/Tat (B) and dual IFN-γ/IL-2 responses specific for Gag (C) and for Rev/Tat (D) at baseline and after 28 days treatment (Day 29) were measured by ELIPSOT (spots/million PBMCs). Horizontal red lines indicate mean values. There were no significant differences seen between pre- and post-therapy analyses suggesting that VS411 had no immunosuppressive effect on HIV-1-specific immune responses.
