Cerebrovascular MMP9 expression in CAA-NH and CAA-ICH cases. Representative examples of MMP9 staining in a CAA-NH case (a), and a CAA-ICH case (b), representing the median values as shown in c. Leptomeningeal vessels are stained in both cases: in CAA-NH many vessels are only partially stained, whereas in CAA-ICH cases many vessels are fully stained. Overall, CAA-ICH cases had a significantly higher percentage of MMP9-stained leptomeningeal vessels (either fully or partially stained) compared to CAA-NH cases (c). The numbers of MMP9-stained cortical vessels did not differ between groups (d). Plots indicate median values with interquartile range. CAA-NH = CAA-non haemorrhagic, CAA-ICH = CAA-related ICH. ***p ≤ 0.001
