Expression of the CD69 activation marker on CD3+ CD56+ natural killer T (NKT) cells. PBMC were cultured for 18 h in the absence (baseline) or presence of either an aqueous extraction or an ethanol extraction from SBLS. The aqueous extract triggered a mild, but significant increase in expression of the CD69 activation marker on NKT cells. The ethanol fraction triggered a robust, dose-dependent increase in the CD69 expression on NKT cells. For data points where CD69 expression on treated cell cultures was significantly higher than on untreated cells (baseline, 4.05±0.17), this is indicated (*P<.05). Conditions were assayed in triplicate, and the results shown are mean±SD values from a representative of three separate experiments using cells from three different donors.
