Effect of SP treatment on murine spinal cord (A) CD3+ cell infiltration, (B) Mac3+ cell infiltration and (C) demyelination. Spinal cords were extracted from control or SP 30 mg/kg/day-treated EAE-diseased mice (acute phase). Three segments of each spinal cord (cervical, thoracic and lumbar) were evaluated. For each segment, four different regions of interest were analyzed except for demyelination where the complete white matter was analyzed. Control (n = 9), SP 30 mg/kg/day (n = 9) and 3 days of treatment. (A–B) immunohistochemistry and (C) luxol fast blue staining. Each dot represents a measurement. Abbreviations: SC: spinal cord, SEM: standard error of the mean, SP: SP600125 and WM: White matter. Statistic: Mann–Whitney test, #### < 0.0001.
