Decreased total number of natural killer (NK) cells and increased subset of CD56+ CD16− NK cells in pleural fluid from tuberculous patients compared with peripheral blood mononuclear cells (PBMCs). (a) Percentage of CD3− CD14− CD19− cells and subsets of NK cells from pleural fluid cells (n = 23) and PBMCs (n = 25) were analysed by FACS. (b) Mean value of CD3− CD14− CD19− cells and NK cell sub-populations including CD56+ CD16−, CD56+ CD16+ and CD56− CD16+ subsets from pleural fluid cells (filled histograms) and PBMCs (open histograms) were analysed by FACS (Mean ± SD). Student's t-test was used for statistical analysis. *P < 0·05 was considered significant.
