  Non-human primate models aid to design novel vaccine strategies. We analyzed therefore the dynamics of cellular immune responses induced by a bacille Calmette-Guérin (BCG) / recombinant BCG (rBCG, perfringolysin plus Ag85A/B, TB10.4) prime, subsequent adenoviral (Ad35 expressing Ag85A/B and TB10.4) boosts followed by a challenge with M. tuberculosis (Mtb, Erdman strain) in peripheral blood mononuclear cells from rhesus macaques. T-cell compartment mobilization was defined by CD45RA/CCR7/CD27/CD28 expression on CD4+, CD8αα+ and CD8αβ+ T-cells and functional analysis (STAT-5 phosphorylation) was carried out using multicolor flow cytometry. CD4+ as well as CD8+ T-cells showed a marked decrease in IL-7 receptor alpha-chain (IL-7Rα) expression in vaccinated animals (n=12/12) after the first adenoviral boost, but not in control animals (who received saline).
