Mtb burden in CD44TA-LIP treated (Panel A: Concurrent treatment; Panel B: pre-treatment) vs untreated human MΦ over seven days of infection as measured by CFU assay. During concurrent treatment MΦ were treated with CD44TA-LIP at the beginning of infection (4 h after the infection) whereas during pre-treatment MΦ were treated 24 h prior to infection. B. Secreted levels of pro- and anti-inflammatory cytokines by CD44TA-LIP treated, untreated and uninfected human MΦ at 24 h post-infection/treatment. CD44TA-LIP concentration used: 10 μg/106 MΦ. PT: pre-treatment; CT: concurrent treatment. pg = picograms; MOI used for the experiments=1. Number of MΦ used per replicate: 1x106. h= h. Representative data shown from three independent experiments carried out in duplicate. Bars and error bars represent mean and SD, respectively. *p≤0.05, **p≤0.005, ***p≤0.0005, ****p≤0.0001.
