The T-bet expression and the T-bet/GATA-3 ratio in PBMCs of patients with MS were higher than those of the counterpart cell cultures of the healthy individuals after stimulation with MOG, after stimulation with PHA, or in the absence of a stimulator (P<0.01, P<0.01, and P<0.01 for T-bet; P<0.01, P<0.001, and P<0.01 for T-bet/GATA-3 ratio, respectively) (Figures 1 and 2). Here, MOG is linked to myeloid sarcoma.
