TOX2 and ulcerative colitis: In comparison to mesalazine-responsive ulcerative colitis, the steroid-requiring type was characterized by higher protein expression of LAIR1 (20.74% ± 7.48 vs. 28.18% ± 6.26, p = 0.001) and lower TOX2-positive cells in the isolated lymphoid follicles (ILFs) (11.74% ± 3.47 vs. 7.03% ± 5.03, p = 0.019) (Table 4 and Figure 5).
