A: Reactivity of CD137-high origin PBMC CD4 polyclonal T cell lines from US LTBI subjects to MTB proteins. MTB gene names for IVTT-expressed antigens and control antigens indicated on the X axis. Cell activation detected by 3H thymidine proliferative responses on Y axes; note axes limits vary for clarity. Only proteins with reactivity above the cutoff are shown in descending order. Each cell line was tested with each protein. Each bar is the mean of duplicates. Horizontal dashed lines indicate positivity cutoffs. B: Similar data for two US LTBI-negative persons.
