Fig 1. Percentages of IFN-γ+CD4+ T lymphocytes among non-stimulated (NS) compared to mycobacterial antigens-stimulated ascites lymphocytes.

Fig 1

The percentages of IFN-γ-containing CD4+ lymphocytes were measured by flow cytometry after an overnight in vitro culture of the ascites lymphocytes left non-stimulated (NS) or stimulated with PPD (left panels), HBHA (middle panels) or ESAT-6 (right panels) for TB (upper panels) and non-TB patients (lower panels). Individual values obtained for each patient for lymphocytes left unstimulated and those stimulated with a mycobacterial antigen are linked. NS, non-stimulated. Results obtained in the presence or absence of antigens were compared by the Wilcoxon test *, P<0.05.
