Granulocyte density is higher in the CP of progressive MS patients relative to the control CP. a Maximum projection image of a progressive MS and a control CP immunolabeled with CD66b (red) and collagen IV (white). White arrowhead points to a granulocyte associated with the epithelium and white arrow points to a stromal granulocyte in the progressive MS case. b Density of CP granulocytes in the CP of control and progressive MS cases (Wilcoxon rank sum test with continuity correction). c Density of CP granulocytes in the different CP compartments (Wilcoxon rank sum test with continuity correction). PMS: progressive MS. Scale bars are 100 μm
