Figure 3

The viability of macrophage-like THP-1 cells exposed to Stx1 or Stx2. Macrophage-like THP-1 cells were exposed to 100 ng/mL of Stx1 or Stx2 or left untreated (NT) for 6 hours. An MTT assay was then performed and the absorbance of viable cells was determined at 570 nm. The data represent the means of three trials performed in triplicate ± standard deviation. Asterisks indicate significant differences between Stx treated and untreated (NT) cells (* p < 0.01, one-way ANOVA with Tukey’s HSD test) between treated and untreated cells.
