Same as in (A) but cells were fed with 8 µg of A9M peptide bead and exposed to 12.64-Luc Reporter T cells. Experiments were combined by normalizing RLU values to the average of the negative control I-Ab. Error bars show SD of 3 independent experiments. * p < 0.05 for Rab39a or β2m siRNA vs negative control I-Ab using ANOVA
