Figure 2. Induction of apoptosis in Jurkat cells after incubation with F. nucleatum wild-type or with aimless1. Jurkat cells were incubated with wild-type or aimless1 for 18 hrs before assay (n = 3). Uninfected Jurkat cells were incubated alone as a control. Values shown are relative to wild-type apoptosis levels after background subtraction. Error bars represent SD. **p < 0.0001.
