An earlier study found that the ratio of Th1/Th17 cells was decreased in BD patients with uveitis [5], and another study reported an increase in the ratios of RORC/FOXP3 and TBX21/GATA3 in neuro-Behçet's disease, suggesting a dysregulation of Th1, Th2, Th17 and Tregs in this disease [6]. The gene discussed is TBX21; the disease is Behcet disease.
