TcES treatment abrogates CNS-infiltration. At the end of the experiment, mice were sacrificed to extract the lumbar region of the spinal cord and stain it with H&E to reveal inflammatory infiltration, as pinpointed by arrows in (a). The total infiltrated area of the 5 randomly selected sections per group was calculated and plotted (b), and the number of the lesions per section (c) present on every selected slide was counted to calculate mean and SEM. The data shown are representative of 2 independent experiments. Means and SEM were calculated for a group of n = 5 mice. The statistical significance between groups was determined by two-tailed Student's t-test, ^∗∗∗P < 0.001, ^∗∗P < 0.01, and ^∗P < 0.05.
