Since the T-bet/GATA-3 expression ratio is considered as a useful alternative parameter to determine Th1/Th2 cells status, the current study results support a Th1-biased pattern in patients with MS, which was consistent with data from other investigations in patients with MS (Kostic et al., 2015; Raphael et al., 2015). Here, GATA3 is linked to myeloid sarcoma.
