Both vaccines induced IFN-γ+TNF-α+ double positive CD8 T cells specific for both Ag85B and TB10.4, and interestingly also a minor, but still detectable, population of triple positive antigen specific CD8 T cells (Fig. 2B and D).
Fifty-five percent (16/29) of patients with myeloid malignancies of blood group A, B, or AB had a detectable population of RBCs with decreased expression of A or B antigens compared with no detectable changes in 127 normal A, B, and AB individuals.
These factors did not fully explain the lack of detectable population-level impact because, after incorporation of both the known data and the assumption that IPT cured all infections, the model fitted the data poorly.
explained the lack of detectable population-level impact.
A simpler model than that used here would have excluded some factors and could not determine their contribution to the trial's lack of detectable population-level impact.
We found the following: 1) The model suggests that a small proportion of latent infections among human immunodeficiency virus positive people were cured, which could have been a key factor explaining the lack of detectable population-level impact.
Our analysis, supported by findings from fitting the base-case model to trial data and sampling >2 million parameter combinations, suggests that a possible explanation for the lack of a detectable population-level impact in Thibela TB is that IPT cured a small proportion of latent infections, at least among HIV-positive miners.
Even more recent genomic analyses, however, suggest that a small but detectable degree of interbreeding occurred when expanding modern human populations emerging from the African tropics encountered Neandertal populations in the Middle East around 120,000 years before present (Gibbons 2010).
At the end of the AF (EF stage), the number of Nemea samples with detectable populations decreased to 9%, while counts ranged from 1.3 to 7.0 log CFU/mL.
However, one limitation of this study is that we cannot fully rule out the possibility of a sub-detectable population from the first T cell infusion involved in altering the immunologic milieu for the second infusion.
