Figure 5

The apoptotic index of TW01 and TW01-LMP1 cells when subjected to different cytokines. The level of apoptosis was correlated to the level of hydrolysed p-nitroaniline (pNA) measured at 405 nm. TW01-LMP1 cells were found to have reduced apoptotic index as compared to TW01 cells. Each bar represents the mean ± SD value for assays conducted in triplicates. The term 'Comb.' found in the chart represents combined treatment consisting of IL-6 (100 pg/ml), IL-10 (1000 pg/ml), and TGF-β1 (100 pg/ml). The indication '*' represents the significance of p < 0.05.
