CD68 and stroke disorder: CD68 expression in the CST: In the dorsal-most region of the CST, stroke significantly increased the intensity of CD68 expression, and this effect was significantly reduced in the stroke + CORT group (sham = 2.703% vs. stroke = 21.96%, p < 0.01; stroke vs. stroke + CORT = 5.223%, p < 0.01).
