Fig. 3From: The expression levels of prolyl oligopeptidase responds not only to neuroinflammation but also to systemic inflammation upon liver failure in rat models and cirrhotic patientsPREP activity (a) and protein levels in plasma, determined by western blotting (b), are decreased (p < 0.05) in PCA rats (black bar, n = 4) compared with sham operated control rats (white bar, n = 5). Representative blots are show in the lower panel. c, ammonia levels in PCA are increased relative to controlBack to article page
