Figure 7

Spinal cord pathology in RR-EAE mice induced by IFA+GlcC14C18+MDP. (A) Nissl and Luxol fast blue (LFB) stains of spinal cord sections from RR-EAE-induced mice at day 28 post injection, having an EAE score of 3.5 upon euthanasia. Red boxes highlight cellular infiltration and spatially associated demyelination of the white matter seen by Nissl and LFB staining, respectively. (B) Quantitative spinal cord pathology per EAE score upon euthanasia. Statistical significance was determined by Tukey’s multiple comparisons test. *p < 0.05 and ****p < 0.0001. N = 40 sections for each group (20 from CFA and 20 from synthetic adjuvant of equivalent EAE scores). Lines indicate averages +/− SEM (C), Quantitative spinal cord pathology per adjuvant. Statistical significance was tested with two-tailed unpaired Welch’s t-test; a power calculation for given variances and N = 60 sections per group indicated an ability to discern +/− 15% difference vs. CFA control. Lines indicate averages +/− SEM.
