However, the PBMCs of patients with MS expressed lower levels of GATA3 after stimulation with MOG, after stimulation with PHA, or in the absence of a stimulator, than those of the equivalent cell cultures of the healthy individuals (P<0.03, P<0.01, and P<0.02, respectively) (Figure 3). This evidence concerns the gene GATA3 and myeloid sarcoma.
