Functional characteristics of tuberculosis (TB)-specific CD4 T cells were studied in clinically active pulmonary TB (n?=?21) and high TB exposure including LTBI (n?=?17). Following tuberculin stimulation, activated CD4 T cells were identified by flow-cytometry (CD154 up-regulation, degranulation, interferon ? [IFN-?], tumor necrosis factor ? [TNF-?], and interleukin 2 [IL-2\ production). Interestingly, CD154 up-regulation accounted for ?80% of activated CD4 T cells in the active TB group but just 40% in the controls, whereas IFN-? accounted for only ?50% of activated cells in each group. The frequencies of CD4 T cells displaying at least 1 activation marker discriminated better between the groups than those displaying degranulation or IFN-? production alone.
