a Immunohistochemistry analysis of the expression of AQP4 in the IDO1-low group (n = 5) and the IDO1-high group (n = 5). b Expression of AQP4 was immunohistochemically detected in the TDO-low group (n = 5) and TDO-high group (n = 5). Representative images and the accompanying statistical plots are presented (magnification, ×400 ; scale bar, 50 μm). Statistical significance was determined by Student's t test. **p < 0.01.
