On the other hand, DAT-positive immunofluorescence increased during withdrawal, with higher levels at WD1 than at BD (t = 3.82, df = 24, p = 0.005), and at WD10 when compared with CTRL (t = 7.59, df = 24, p < 0.001), BD (t = 15.8, df = 24, p < 0.001) and WD1 (t = 12.0, df = 24, p < 0.001) (Figure 3B,D). This evidence concerns the gene SLC6A3 and Behcet disease.
