CD69- and NKG2D-expression of NK cell-subsets. Isolated NK cells were co-cultured with monocytes with or without PstS-1 as described above for one and three days. NK subsets were discriminated by additional CD16-staining. CD69-expression (a+b) and NKG2D-expression (c+d) of CD16-positive- and –negative cells were determined by flow cytometry. Means + SE of five experiments are shown. Statistical analysis was performed by unpaired t-test, statistical significance was assumed at p ≤ 0.05.
