In a follow-up study, continuous time point-tracked PBL samples from 9 active PTB outpatients (Table 4 and Figure 5) were drawn every month during regular, 6-month-long, anti-TB treatments in order to assess the changes in the percentage of TCR tetramer-bound CD14+ monocytes using eu- and hu-tetramer staining and flow cytometric analysis. This evidence concerns the gene CD14 and tuberculosis.
